1. Ecosystems.
(10 pts) Provide a review of the process of succession and trends in biodiversity, productivity, and nutrient cycling.
Ecological succession refers to the process of gradual change of the ecosystems. This is attributed to the fact that habitats do not remain constant and they keep changing over time. Succession is divided into two; there is primary succession and secondary succession. Primary succession refers to changes which occur on an environment that has never been colonized before, for instance, quarrying on land that has never been quarried before. Secondary succession on the other hand involves environmental disturbance ...

In this course we looked into the different kinds of toxins that affect the nervous, cardiovascular and endocrine system (Lu, Kacew, & Lu, 2003). The political, religious and social tension among different countries and communities, poses a constant threat of terrorism and war. Use of biological weapons like bacteria, viruses or toxin in the war is called biological warfare. Staphylococcus toxin and Botulinum toxin are the commonly used toxin in biological warfare. The use of biological warfare is an age old practice. There are several recordings in the history where biological toxins like ergot poison, hellebore, Barbarossa, human feces, leprosy ...

Cholera Toxin Enhances Vaccine-Induced Protection against Mycobacterium Tuberculosis Challenge in Mice

This experiment is an animal experiment made in accordance with the basic guideline the UK Animal Act 1986. Methods use was by collecting mice of 6-8wks. BCG Pasteur vaccine administered. Others vaccines are MVA85A and cholera toxin. Intradermal agents administered are the anti-IL-1A blocking antibody and the isotype IgG2a. Animals were then challenge with Biaera AeroMP aerosol nebulizer at a targeted pressure and dose. Organ harvest and stimulation for immunogenicity was then done. The lungs and spleen are the organs harvested aseptically. The organs were then processed with different steps such as mincing and digestion with DNase/collagenases. The cells collected ...

The title of the study says it all and is quite descriptive. It reflects enough about the content.

According to the author, this new finding will help in the development of new kind of treatment against this toxin. Well, though toxin has been found to sneak into the cell, it does not mean, it will help a lot in the making of new treatment. Possibility ...

Abstract

European Gypsy moths cause severe damage to trees and shrubbery by reducing the ability of the plants to carry out photosynthesis. The moths damage the plants causing the plants to die and/or to become vulnerable to infections. Plants are defoliated forcing the plants to grow new leaves disrupting the natural growing process of the plants. The environmental damage the moths cause results in loss of wooded areas, drought and high economic costs. The carbon cycle is disrupted due to the loss of trees. Gypsy moths are regarded as the worst insect pests in the United States. The infestation started ...

Why I choose AcuCare Centre?

As a part of the field assignment, I visited the AcuCare Centre, 12133 Pembroke Road, Pembroke Pines, FL33025. I choose this particular place for my assignment, as I wanted to know about the method of “healing through touch”, as I would call it. Reiki is an alternative medicine that is sought by many for stress and chronic diseases. My aunt is particularly supportive of the center and has recommended it to me. She has sought alternative medicine to treat her migraine problems. She found allopathic medicine ineffective and replete with side effects.

Initial impression of the center:

On entering the center, there was a ...

Abstract

European Gypsy moths are regarded as the greatest insect pests in the United States as they have been reported to cause severe damages both to the environment and the economic features. These insects are believed to have emerged from Massachusetts after they were accidentally released by a professor who was doing research on silk production. They later spread across the United States through two different ways. One, they spread across short distances naturally where the caterpillar stage climbs to the top of a tree and spin a silk thread which allows them to be blown by wind a process called ballooning. The second ...

Introduction

Biochemistry is the study of composition, structure and the chemical reactions taking place in living organisms. Dental biochemistry is the study of the composition, structure and chemical reactions taking place in teeth (Chary & Sharma 2004). The teeth form the sensitive part of the human being. The teeth enhance the looks of a human being and it is also for eating. When the dental formula of a human being is correct, the confidence to talk improves unlike when the dental formula is not proper. When care is not taken, the teeth will contact diseases. There are various causes of the diseases in ...

E COLI O157

WHAT IS ECO157?
Enterohemorrhagic Escherichia coli O157 or otherwise known as “EHEC O157” is also called as the “verocytotoxin” which produces “shiga toxin” and the end result is EcO157 (Islam, et al., 2014, p.1). The E coli O157 has been reported as a food-borne pathogen known world-wide. One of the harmful effects of E coli O157 is that it can create hemorrhagic colitis that carries severe sequelae such as the hemolytic uremic syndrome as the product of the “shiga toxin” that came from the organism that can act on the human kidney, intestine and other parenchymatous organs (Islam, et ...

Food Safety

Escherichia Coli commonly called E. coli is a variety of bacteria that is seen in the human intestine, and in the intestine of animals including big mammals. Even though many varieties of E. coli will not harm humans, certain varieties can lead to diseases. The most notorious version of E. coli is the E. coli O157: H7. This variety of E. coli leads to acute diarrhea in humans, and can even lead to serious medical conditions that cause harm to the kidneys. This variety of the bacteria produces a hazardous toxic compound called the Shiga toxin. Hence, this strand ...

1) Lionfish, belonging to the genus Pterois, is native to the Pacific and Indian oceans. They inhabit the coral reefs and lagoons and predate the small fish. Lionfish is now abundantly encountered in the United States East coast and Caribbean Sea.

There is a speculation that the lionfish was released from an aquarium in South Florida in the hurricane Andrew in 1992, although the lionfish was first discovered in the South Florida much earlier in 1985. In the last two decades the lionfish particularly the P. volitans species has expanded largely across Western Atlantic and Caribbean (Albins and Hixon, 2011). ...

Genetic modification, as the name suggests, is a biotechnological process by which the genetic material in an organism such as plants is altered in a manner that does not take place in the nature or via nature-influenced recombination. Such organisms which are called as the Genetically Modified Organisms or GMOs find immense practical applications in the modern times. They are used extensively for carrying out medical and biological scientific work, are used to manufacture new pharmaceutical medications and importantly, are used in agriculture to produce good quality crops. The reason why genetic modification has gained prominence in agriculture is because it ...

Introduction

Air pollution is a very strange phenomenon yet it is one that causes severe damage to e person’s health as well as to every other infrastructure that stays in between the community. Air pollution has numerous causes of concern in the modern world and these causes, instead of deteriorating, are only increasing on a daily basis without much cooperation to their basic destabilization . As much as it is the responsibility of world leaders to evoke the world of air pollution, they seem to be halted by business magnates who refuse to stop their mega invested projects in a bid to work ...

The concept of power is addressed in the video in an indirect format. The reality is that the power is used in the life-cycle of stuff. Firstly, in the extraction process, power is used to cut down, mine and get all resources needed in the production. The amount of power needed in this process is immense as it deals with the use of explosions to get the minerals even in the highest mountains. Power is useful in making machines move and perform as expected. In the production process, power has to be incorporated to ensure that the manufacture proceeds ...

His mouth is open and his facial muscles appear to be pulled back tight. My first impression and thus diagnosis is that the patient is ...

Discuss how a cell will change or alter itself in response to stress. Address different types of adaptation or change along with what might be the reason that brings about the changes.
A cell will change depending on the stress causing it. Stress to a cell can be caused by changes in temperature, oxygen levels, and toxins (Braun and Anderson, 2006). Cellular responses include a reduction in number, change in size and structure. The different adaptations are addressed below.

Atrophy

This refers to a decrease in the cell size. This may result from a decrease in the number of functions a particular cell produces (Braun ...

1. Introduction

According to the Food and Agriculture Organization of the United Nations (2010), nearly one billion people suffered from hunger in 2010, representing nearly 16% of the population of developing countries. At the same time, the world population is growing and global warming threatens the production of crops. Profound changes are needed in the way that food production and food consumption are perceived, or the world may face mass starvation. Genetically modified (GM) technology has been found capable of feeding the world but there are concerns regarding its safety (Moseley 2002, Carpenter 2010). Consumer acceptance of GM foods in the ...
