Essays on Carbon Dioxide And Water

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

There are environmental chemical processes which require light to react. These processes are called photochemical reactions. Photochemical reaction is commonly initiated due to the absorption of solar energy or light. When molecules absorb energy in the form of light, the atoms are converted in a transient excited state (Larson & Weber, 1994). This transition state or excited has completely different physical and chemical properties with the initial state of the molecule. The excited states also have more tendencies to react since they are considered stronger acids and stronger reductants that the initial state of the molecule. The excited state of ...

Properties of Life

When it comes to dealing with cells as a structural and functional unit of all kinds of life on earth, it is important to understand the biological concept of what constitutes life. Most biologists, including cell biologists will agree that life is defined according to seven principles. First, that living things are composed of cells. A cell is a unit that makes up all kinds of life, whether it is a bacterial life or plant life or human life. The second principle is that there are different levels of organization in life – cells make up tissues, tissues make up organs, and so ...

1.0 Lab 1: Heating Value Measurements: Solid and Liquid Fuels with a Bomb Calorimeter 1.1 Introduction Measurements of heating values can be derived for both solid and liquid combustible fuels using an Oxygen Bomb Calorimeter. The calorimeter measures heat. Heat is not the same thing as temperature. The heat of combustion is called the calorific value. The calorific value is “:the number of heat units liberated by a unit mass of a sample when burned with oxygen in an enclosure of constant volume” (Introduction 2007). The experiment uses the 6100 Bomb Calorimeter. The definition of calorific value in a bomb calorimeter ...

Homeostasis is the propensity of an organism/a cell to direct its internal situation, typically by a system of reaction controls, for the health and functioning to be stablelized, despite the outside altering conditions. The capability of the body /a cell is to look for and uphold the state of stability inside its internal environment while it’s dealing with the outside changes. Homeostasis takes place when the body regulates its temperature so as to try maintaining an inner temperature.eg in hot days we sweat to cool off, also we shiver to generate heat in the cold season. Homeostasis use hormones to ...
