Introduction

Cellular respiration and photosynthesis are vital reactions in living organisms since without the two; there would be no life on earth. Cellular respiration involves a set of metabolic reactions that take place in cells of living organisms thereby converting nutrients like sugar into adenosine triphosphate (ATP) (Osterhoudt & Barhydt, 2010). On the other hand, photosynthesis involves the conversion of carbon dioxide into organic compounds by the photoautotroph in the presence of sunlight. Most animals attain their energy requirements through cellular respiration while on the other hand; photosynthesis is performed by most plants that can make their food. These two reactions ...

Introduction

Eukaryotes especially multi-cellular organisms, plants and animals, actually have a mutual relationship that entails interdependence between them. This relationship is based on several factors but the most significant and fundamental one is the exchange of oxygen and carbon dioxide. As a matter of fact, plants are the chief sources of organic material in all living things through the process of photosynthesis (Hopkins, 2006). This paper basically tries to demonstrate and illustrate the mutual benefits that exist between plants and animals for survival.

Discussion

According to Hopkins (2006), plants are the chief source of organic matter in nature especially carbohydrates, proteins, vitamins, fats ...

Describe the difference between an obligate and a facultative aerobe.
Obligate and facultative aerobes are the same in terms of their ability to use oxygen in their respiration process. However, obligate aerobes requires oxygen to oxidize substrates such as sugar and fat to produce ATP (energy). Obligate aerobes are more efficient in converting substrates to ATP. The key process in aerobic respiration is the conversion of sugar to ATP shown in reaction 1 below:

In the reaction 36 molecules of ATP is produced per molecule of glucose. It is actually a slow process which comprises 3 ...

Introduction

The exchange of respiratory gas is limited by the capacity of the respiratory muscles to circulate air in the lung. Ventilation fails when muscles do not have the capacity to cope with the load brought by the mechanics of the pulmonary system. It is crucial to comprehend the mechanics of respiration/breathing not only for purposes of diagnosing how the system has failed and to offer the correct prescription for treatment of the failure, but to be capable of providing the most effectual temporary respiratory support through the use of a mechanical ventilator, as well.
The first category explains the ...

The cardiovascular and respiratory systems are largely responsible for the transportation of oxygen and carbon dioxide through the body. Respiration consists of both inspiration and expiration. These actions are the methods by which essential oxygen is exchanged with harmful carbon dioxide. While oxygen is brought into the lungs during inhalation to be processed throughout the body, carbon dioxide is brought during exhalation to be removed from the system entirely. Once the oxygen has reached the lungs it is taken up by the bloodstream in order to be distributed to the various cells that require a constant exchange of nutrients ...

Global warming and climate change are two different terms that have been used over the years to describe different phenomena. Global warming refers to a subsequent increase in the global average temperature (Black & Weisel 5). On the other hand, climate change refers to global climate changes due to increasing average global temperatures brought by changes in rain patterns, increased drought and heat waves. These future projections in the change of global rainfall patterns can be derived from the Intergovernmental Panel on Climate Change (IPCC) reports over the years. The argument that the use of term global warming has been ...

Introduction

Ethylene is a naturally occurring hydrocarbon gas, although it can also result in combustion of large chained hydrocarbons. Additionally, it is the simplest gaseous organic compound of the alkene group. Statistically, it is the most commercially manufactured gas globally since it has several industrial applications. The gas is odorless, and climacteric fruits do produces the gas as they begin to ripe, for instance, apples. During the fruit ripening process, the gas is responsible for color changing, softening of the fruit as well as the change in texture in addition to other processes too (Abeles et al., 2012 n.p).

Abstract

Scholars across the board have been persistent on the need for the near perfection of the concept of vital signs monitoring. Prior contributions to this field of knowledge all seem to bend towards correcting the wrongs that at times overwhelm the nursing practice, while at the same time constructing updates and ingenious suggestions towards the bettering of methods of monitoring vital signs. This paper cuts across the dimensions of nursing practice as applied in a reflective situation, and the evaluative outlook into the perks of vital signs monitoring as a physiological assessment process, its outcomes, and its repercussions both ...

Introduction

The study of human body movement assists in understanding different biomechanical, psychological, and physiological mechanisms of the body. Taking care of a newborn from the time of birth to the age of about twelve months requires the mother or the caregiver to understand some concepts necessary for the survival of the baby. According to Davis, Cladis & Motoyama (2011), the breathing pattern of newborns from up to the age of six months is purely diaphragmatic (abdominal), hence; the need to understand various positions that allow the infant breath effectively. Understanding diaphragmatic breathing patterns acts as one of the major clinical ...

The cardiovascular system consists of blood, the heart, and the circulatory system, which includes veins, arteries, and capillaries. The function of these organs is to transport oxygen from the lungs to cells throughout the body. Each organ system in the body is essential in providing homeostasis in the human body. However, the actions of the cardiovascular system are critical to human life. Many physicians, scientists, and other professionals dedicate their life to the understanding of the cardiovascular system and its diseases so that people can live longer and more productive lives. This paper will discuss the general anatomy of ...

Cells are the building blocks of many structures in biology. In their most basic classification, there are prokaryote and eukaryote cells. These two cell types differ in their structure. Prokaryotes typically consist of ribosomes, a cell membrane, and nucleic material. On the other hand, eukaryotes contain membrane-bound organelles, such as Golgi apparatus, lysosomes, a nucleus, and endoplasmic reticulum. Both types of cells also have nucleic acid as a form of genetic material. The prokaryote has circular DNA which is not associated with histone proteins; whereas the eukaryote has linear DNA with histone proteins present to help organize and protect ...

Introduction

Performance enhancement in sports has been a controversial topic over the years. Specifically, sports organizations prefer the utilization of performance enhancement drugs to enhance their efficiency in the sporting activities while other humanitarian and government organizations raise concerns over the negative impacts of these drugs. As such, this paper discusses the negative impacts associated with performance enhancement drugs to the human body and the ethical concerns that emerge from this approach. In many instances, PEDs have been reported to enforce significant resiliency among the users and this is an advantage to sportsmen due to the enhancement of biological functions ...

Question 1.
Insect-eating birds will decrease in number since their source of food has been reduced. The birds may also migrate to warmer areas during this period.

Question 2.

The habitat is the specific place where the organism lives e.g. a fish’s habitat is water. On the other hand, niche is the position and the role played by the organism in an ecosystem. It includes how the organism obtain food and shelter, the mode of survival, and the mode of reproduction (Sutton & Anderson, 2009, p. 46). For instance, a lion’s niche in the ecosystem is that of a predator.Question ...

The earth’s atmosphere can be defined as a series of progressively arranged “shells” or “spheres” held to its position by the force of gravity. Just to mention, the earth’s atmosphere exerts pressure to the earth’s surface which is referred to as the atmospheric pressure. In addition, the earth’s atmosphere covers a region of about 480 kilo meters around the earth’s surface after which exists the exosphere. Also, the earth’s atmosphere is further divided into heterosphere and homospere. Homospere is the layer 80 kilo meters just above the earth’s surface that has a uniform chemical composition ...
