BIOL 101 September 15‚ 2012 Assignment 1 Chapter 1 2. What is Homeostasis‚ and why is it important? Give some examples that show how systems work together to maintain homeostasis? Homeostasis is a term used to describe an internal environment being in a state of constant conditions‚ such as constant temperature‚ pH‚ and etc. It is important because staying at an equilibrium requires the least amount of energy and provides the perfect environment for desired reactions to occur. If at any given

Biology - Main Questions And Answers: Complete the table with a tick if the statement in the first column is true‚ for each process. Write a simple equation to show how ATP is synthesised from ADP: ADP + Pi ATP Give two ways in which the properties of ATP make it a suitable source of energy in biological processes: 1. Energy released in small/suitable amounts 2. Soluble 3. Involves a single/simple reaction Humans synthesise more than their body mass of ATP each day.

Organ Trafficking Organ trafficking is one of the great issues that is faced by the society today. It is a practice of stealing people’s organ through surgery under the influence of drugs or from a dead person‚ and the organs are normally sold in black market such as China. South Africa‚ and Russia. WHO has estimated that one-fifth of the 70‚000 kidneys that are transplanted every year come from the black market through a widespread organ-trafficking networks. In my opinion‚ organ trafficking has

In biology species can become isolated from other species through a number of processes. These isolation processes keep the two species from interbreeding and producing hybrid offspring. There are five separate isolation processes that prevent two species capable of producing offspring from being able to do so. Ecological Isolation Ecological‚ or habitat‚ isolation is when two species that could interbreed do not because the species live in different areas. For example‚ in the wild of India both

Biology- Maintaining a Balance Summary 1. Most organisms are active in a limited temperature range 1. identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates Enzymes are proteins which act as catalysts in living things (they lower the amount of energy needed for a reaction‚ therefore increasing rate of reaction). Enzymes speed up reactions but are not used up by them. Enzymes catalyze only one

In 1984‚ George Orwell has demonstrated the possibilities of two main characters who have contradicting traits can fall deeply in love. Although they are both secret rebels of the party and they both hate the Party’s totalitarian power in Oceania‚ Winston and Julia still bear a striking difference from each other. They are different in physical appearances‚ their views upon life‚ and their motivation towards the rebellion. Despite their contrasting beliefs and traits‚ the couple still manages to

Experiments investigating the effect of a particular factor on an enzyme-catalysed reaction are commonly used as assessed practicals in Biology. The reason for this is there are a number of factors that can be investigated‚ and therefore‚ a number of factors that can also be controlled. From our lecture‚ we are aware that the following can affect the rate of reaction: 1) Temperature: a. Independent variable: A range of temperatures should be investigated‚ with particular attention
