Abstract

Recently, attention has been diverted to clean, alternative and renewable technologies due to the depletion of petroleum resources and increase of the green house gases from the combustion of fuel resources. Fuel cell is the fore-runner of these technologies and has received immense impetus due to its relatively clean source of energy. Fuel-cells are devices that produce electrical energy from chemical transformation reactions. Electrodes are placed within an electrolyte medium that facilitates oxidation of fuel. In these electrochemical reactions, ions are generated that generate electricity. This electrical energy can be effectively harnessed to carry out a myriad of functions. Continue reading...

Spina bifida is neural tube defects that are caused by ecological and hereditary factors that are not yet fully understood. There is no known cure yet for Spina Bifida condition, the damaged nerve tissue cannot be replaced. Some surgical interventions depend on the severity of the disease. In the worst case scenario, if the severe conditions are detected earlier through ultrasound, abortion is recommended.
Folate, also called folic acid is a B group vitamin that can prevent most neural tube defects. The recommended dose for the women who are planning to become expectant is 0.5 mg every day for Continue reading...

Consumption and Metabolism1–3 Analytical Summary

The main topic addressed by this review is Fructose and whether or not the fructose hypothesis is valid. It presents new information that (at the very least) arouses the consideration that fructose alone is not the evil culprit of diseases for which it was blamed. It suggests that fructose was unfairly evaluated. This is based on the fact that fructose is ingested alongside of other causative agents such as food additives, fats, other types of sugars and preservatives. Meanwhile, none of the other additives were put on trial in the same manner. He positions the reader to consider that Continue reading...

Protein synthesis is the process through which the biological cells produce new protein molecules. The process helps in balancing the cellular proteins that are lost through export or degradation. The synthesis of proteins occurs through a series of processes known as translation where the ribosomes are the organelles that are involved in the creation of proteins. Translation is a part of gene expression using the messenger RNA or mRNA that is produced through transcription of the DNA molecule. The produced mRNA is then decoded to produce a chain of specific amino acids using the ribosome complex. The amino acid Continue reading...

There exists about 300,000 plant species on earth, and every individual plant hosts one or more endophytes. However, it is just a few of these plants that have been researched relative to their endophytic biology. Hence, the chance for isolation of new, as well as, interesting endophytic bacteria in plants are important. Endophytic bacteria can be referred to as bacteria that can be isolated from tissues of a surface-disinfected plant or bacteria extracted from inside of a plant, which cause no visible negative effects to the plant. Almost every plant is populated by varied bacteria referred to as Continue reading...

Introduction

Golden Rice refers to the rice that was developed by scientists for the purposes of supplementing the need for vitamin A. The reasons behind the efforts that were marshaled to push for its discovery were along realms of the urgency and the need to salvage the effects of lack of Vitamin A in most foods (Schulze). As a result of the lack of the vitamin, many children in the world are suffering. Ultimately, several deaths had been reported. At the same time, medical reports dictate that, pregnant women are also greatly affected by the lack of Vitamin A. For Continue reading...

Alzheimer's disease (AD) or dementia of Alzheimer's type (DAT) is one of the most common pathologies of the central nervous system and psyche. It usually affects persons in the old age and today an estimated of 500,000 Canadians suffer from Alzheimer’s or related dementia, over 70,000 being under 65 and 50,000 under 60. Neurodegenerative process is accompanied by progressive loss of memory and cognitive abilities decline. AD inevitably leads to death of the patient, and there are still no drugs to prevent or cure this disease. Incidence increases parallel with an increase in life expectancy. Continue reading...

Abstract

All cells in a living organism require energy to drive various cellular activities such as transport of molecules and movement among others. The rate of cellular respiration may be affected by the substrate concentration, pH level and enzyme concentration among other factors. This experiment aimed to study the rate of cellular respiration in isolated mitochondria under different conditions. It was hypothesized that if the concentration of the substrate is increased then there will be an increase in the rate of cellular respiration. Mitochondrial suspension was used as the source of succinate that was used as the substrate. The level Continue reading...

Introduction

Coca-Cola is a giant in the soft-drink industry. It is an autonomous company that traces are foundation from 1886. Coca-Cola came to existence after a pharmacist called Dr. John S Pemberton from Atlanta came up with a refreshing drink that was sold at soda fountains. Later, Frank M. Robinson named the refreshing drink ‘Coca-Cola.’ In 1992, Coca-Cola produced PowerAde as the official refreshment drink in the Olympic Games. By 2007, Coca-Cola ventured in the production of energy drink and vitamin water has made the company profile improve significantly. Despite the challenges that are experienced in the industry, Coca-Cola company Continue reading...

Fast foods are not new phenomena; these are foods that are quickly prepared and served. It traced its origin in the US in the 1950s. In a typical setup, these foods are served in restaurants, and other food outlets close to the people. The ever growing popularity of such foods has been to blame on the laziness of the people (especially college students) who seem to prefer precooked meals to well cooked meals. These types of food are common among the children in the colleges, both local college students and international college students. These types of food include, desserts, Continue reading...

Introduction

An enzyme refers to a molecule that is protein in nature and works as a biological catalyst. The enzyme possesses three major characteristics. The first characteristic is that they act to increase the rate at which a given reaction takes place. This enables most cellular reactions to take place at up to million times faster compared to their rate in the absence of an enzyme. Secondly, most enzymes act specifically on a single reactant known as Continue reading...

Vitamin C Clock Reaction: Kinetics

Abstract

Collision theory refers to a theory that was proposed by Max Trautz and William Lewis independently. The theory qualitatively offers an explanation on the way chemical reactions take place and the reason behind differences in reaction rates in different reactions. The rate equation for a given chemical reaction refers to the equation that provides a link between the pressure or concentrations of the reactants and the parameters that are constant partial reaction orders and the rate coefficients. This experiment aimed to determine the rate of reaction of reaction between iodide and hydrogen peroxide and Continue reading...

Junk food is a slang term for food that is rich in fat, sugar, salt, and calories, but with little protein, vitamins or minerals. Therefore, this food is of little nutritional value. Salted snack foods, sweet desserts, gum, candy, fried fast food, and soda are the examples of junk food. These foods are tempting because they are widely available, convenient and cheap. For example, in the United States only $165 billion was spent on it in 2010 (“10 States That Consume Too Much Fast Food”). Another research shows that in recent decades consumption of junk food has increased dramatically, Continue reading...

Introduction

Most of the world’s chronic diseases are preventable by long term dietary behavior. Out of the ten major causes of deaths for Americans, diet is a contributing factor to at least five of them. These diseases are such as cardiovascular diseases, cancer and diabetes. A report by the Joint World Health Organization on diet made in 2003 revealed that, most of the world’s chronic diseases can be prevented by regular physical exercise and maintenance of a healthy weight. This finding is valid up to date. According to this report, a person’s genome determined their susceptibility to Continue reading...

Factors such as race, sex and age may be significant benchmarks in the analysis or understanding of epidemiological details such as incidence and mortality rates of oral cancer.1 For instance, the incidence and mortality rates in men are twice more than in women.1 Based on race, African American males have a higher incidence rate than White males.1 This also applies between a comparison between African American females and White females respectively.
Despite the occurrence of new cases of oral cancer, the overall incidence rate trend over the last 30 years has been declining.2 The incidence rate of oral cancer Continue reading...

Mountain pine beetle (MPB) (Dendroctonus ponderosae Hopkins) is a bark beetle that lays eggs within the vascular system of the mature trees of lodgepole pine (Pinus
contorta). First known epidemic infestation was recorded in 1994 in the forests of British Columbia (BC). Prior to 1994, the infestation was negligible, owing to the fact that extreme low temperatures of winter killed the beetle, thereby curbing the problem. In the past two decades, however, due to global warming the winter temperatures are not low enough to kill the beetle. This has escalated the problem of deforestation and thereby has unbalanced the Continue reading...

Introduction

Dietary fiber is a combined term for a diversity of plant matters that are resistant to digestion by human gastrointestinal enzymes. Dietary fibers can be categorized into two major groups according to their solubility in water. In humans, natural gel-forming fibers (gums, pectins, mucilage, and the remains of the hemicelluloses) are soluble. Whereas the matrix fibers or the structural (lignins, some hemicelluloses, and cellulose,) are insoluble, Dietary fiber and whole grains are among the best sources of nutrients including minerals, a slowly digestive energy and vitamins. (Byrne, 2011). They also contain phytochemicals such as carotenoids, lignans, inulin, beta-glucan and Continue reading...

The earth as we see it is composed of different components that make up the earth we know day. These components vary from the physical elements that are seen by the human eye to strange and unexplained forces that are in the visible elements of the earth. This has triggered the scientists to devise ways in which they will understand fully what happens on earth and why it is in the shape it is today. The scientists through governments have sent into space different space satellites that are able to help them get the desired knowledge of the different Continue reading...

C3 and C4 photosynthetic pathways

Plants have the ability to grown and survive in a number of different environments. They can adapt from hot and dry to frigid temperatures. In order to adapt to various environmental conditions plants have to adapt and develop mechanisms to survive different conditions. One mechanism of adaptation involves the mode of fixing carbon dioxide. Carbon fixation is the process of incorporating inorganic Carbon to an organic form. Photosynthesis is the process of carbon fixation used by the plants. C3 plants usually are found in cold, temperate climate and are most widely distributed worldwide. They use environmental carbon-dioxide (CO2) and Continue reading...

Introduction

Blood consists of erythrocytes and leucocytes suspended in it. Blood is pumped from the heart to the body through the arteries and it enters back in the heart through the veins. Blood without cells is known as plasma while serum is the straw colored liquid obtained after the removal of the clot. Plasma contains different proteins, nutrients and waste materials. There are different cases of blood disorders observed in humans.

Blood cells and platelets

The most abundant cells in the blood are the anucleate, biconcave erythrocytes. They contain a red pigment known as hemoglobin (Hb) that carries dioxygen (O2). Hb contains four subunits Continue reading...

Consumption of 17g of arginine for two weeks has been found to enhance collagen production, according to a recent study (Crowe & Brockbank, 2009). But, what is a wound? Brown (2013) suggests that wounds are injuries on tissues or the skin, and are prominent in bony areas. Various factors contribute to the development of wounds, but this paper will evaluate the role of calorie malnutrition. This paper examines how high calorie diet promotes wound healing.
Enteral and oral nutritional support is of vital significance according to Crowe and Brockbank (2009). A randomized study that was centered on arginine analyzed how Continue reading...

Inappropriate Usage of Natural Resources

Introduction
Natural resources include oil, gas minerals and forests. Exploitation of these natural resources influences the economic development through earning of foreign exchange in exportation of these resources (Lodhi and Makki, 2010). According to Busse and Groning (2011), natural resource abundance influences the economic and social development of a country. Hence in certain countries polices developed may overlook the exploitation of the natural resources. However, natural resources are by nature scarce and their overexploitation by humans is increasing (Lodhi and Makki, 2010). Human activities are significant in influencing environmental changes that have resulted to development of global warming. Human Continue reading...

Pollution and the Human Body
The human body has an incredible defense and healing system. It uses the various senses like smell, sight and taste to filter the food, air and water as they get into the body. The skin safeguards the body tissues and internal organs from environmental hazards. The skin also senses the variations in environmental temperatures and acts as the body’s stimuli in controlling the body temperature. The brain and the nervous system are part of the complex response and flight mechanism that responds to emergencies and dangers. An army of white blood Continue reading...

Human Impacts on Salt Marshlands

Salt Marshes
Although less regarded by the public as an important ecosystem, salt marshes are among the most fertile and abundant coastal habitats on earth. According to Bromberg Gedan, Silliman, and Bertness from Brown University and University of Florida, Gainesville (2009), salt marshes provide more ecosystem services (anthropogenic benefits from nature) to coastal populations than other ecosystems. These intertidal habitats are composed of salt-tolerant grasses, herbs, and low shrubs, in great depths, and serve many functional dynamics. Salt marshes are located in a range of climates, from arctic and subtropical regions, and are always found along global coastlines. The Continue reading...

Lesson 5 Answers:

24.) Plants are classified into four major groups: Bryophytes, Pteridophytes, Gymnosperms and lastly the Angiosperms. Bryophytes are the plants that do not have true vascular systems, which consist of the xylem and the phloem. In this group, includes the mosses, liverworts and hornworts. Together, they are considered as land plants that reproduce their own asexually by producing spores. Spores are produced in the ‘sporangium’ (plural sporangia), a bulb-like structure located at the top of the stalk. It can only be seen through the use of high powered microscope. Because they lack vessels that can bring the nutrients from the Continue reading...

Recent research has shown the importance of breastfeeding to infant babies for healthy growth and development of important organs such as the brain. Children who are breastfed developed a high IQ and a good cognitive functioning ability. The infant gets the nutrients from the mother inside the worm and through breast-feeding after birth. The mother's milk has important nutrients such as fatty acids (which promote neuronal growth), iodine, vitamins and carbohydrates. Prenatal maternal nutrition is concerned and addresses the nutrients that the infant gets during the pregnancy after birth which have an impact on the infant birth weight and Continue reading...

I have witnessed many things in my life. Some of these instances have been happy and some of them have been sad. Unfortunately, one that has stuck with me concerned a dog I knew that lived across the way from me in Southern California. His name was Raphael and he looked well taken care of: his coat was shiny and he never looked like he was being starved. However, the look of abandonment and loss of love in his eyes is something that will stay with me forever. It showed me that animals need more from their owners than Continue reading...

Statistical inference

Let’s first examine what it means in statistical terms. Say, for example, we are evaluating employees on parameters such as; sales, customer approval ratings, and manager’s ratings. But, sales are calculated in dollars, customer approval ratings on Likert’s scale, and manager’s ratings have a maximum score of 40. If we don’t convert these ratings into standard scores, we will end up comparing apples to oranges. So, to convert these scores into a standard score, we first subtract mean score from it. Then we divide the remainder by standard deviation. The result is a standard Continue reading...

Introduction

The term “risk factor” is very common in epidemiology. In general sense, it refers to a particular variable that is associated with an elevated risk of infection or disease. Since the number of diseases in the world is very large, the number of risk factors is also every large. The risk factors however vary from one disease or infection to another. However, there are a number of risk factors that are very common and play a significant role in many infections. One of these factors is molecular genetics. As the name suggest, molecular genetics is a genre that mainly Continue reading...

Coastal towns are those towns that have a coastline. A coastline is where the land and sea or ocean joins together. A coast normally refers to the region around which sea and land form a link. Examples of coasts include pelagic coast and gulf. A pelagic coast is one that faces the ocean in an open manner. A gulf coast is also known as bay and is more sheltered than a pelagic coast. The coastal regions are very important to the ecosystem. The rivers that join the ocean have fresh water while oceans have salty water. The mixture of Continue reading...
