Biology Coursework: Preliminary Work 8/12/2013 Intro I am going to investigate a factor that affects the rate of enzyme activity What are enzymes and how do they work? Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse - one enzyme will react with molecules

Sonia St James Investigation: Factors that affect the outcome of enzyme activity Introduction In this project I will monitor the rate of activity of Catalase. Catalase is an Enzyme which in the right conditions catalyses the decomposition of Hydrogen Peroxide into water and oxygen; 2H2O2 + Catalase >>> 2H2O + O2 Catalase is found in all cells and protects them from Hydrogen Peroxide which is a dangerous waste product that needs to be eliminated. Without Catalase living things could not survive

Factors Affect Communication Process FACTORS THAT INFLUENCE THE COMMUNICATION PROCESS Perception Perception is a process by which the meanings of messages are interpreted. The way messages are perceived is related to a combination of a person’s social and cultural influences‚ gender‚ educational background and knowledge‚ and past experiences (Schuster 2010). This complex mix of influences means that no two people are likely to perceive the same message in exactly the same way. Some of the strongest

can also be challenging as you adapt to new ways of doing things.Studying in a new school means a lot of changes in your life including absence from family and friends‚ meeting new friends and developing networks‚ learning new social customs and behaviours‚ experiencing a different climate and different foods. It will take time to get used to different ways of doing things and to develop a new network of support. You will find new friends‚ perhaps a teacher‚ a community member or a flat mate who

developing skills required to determine and justify decisions in given situations. Furthermore‚ they work to enhance and shape an individual’s ethical beliefs and values. There are a number of ethical theories that have been introduced throughout nursing including the widely agreed upon four; deontology‚ utilitarianism‚ virtue ethics and ethics of care. Of these four‚ the ethics of care theory is the strongest and most readily relatable to the profession of psychiatry and nursing while the three aforementioned

other mammals base their behaviour upon. Marine mammals often need to communicate great distances‚ and the water does not support visual cues over great distance. This is why whales and dolphins use primarily auditory signals. Auditory signals can travel great distances and travel four and a half times faster in water than in air (Ford‚ 1984). Killer whales or Orca (Orcinus orca) are very social dolphins and live in pods often consisting of family members from between four up to fifty for residential

ability of oral communication. Another factor that my classmates and I thought is the most important factor in second language acquisition is motivation. It is logic to say that learners‚ who are motivated‚ will learn more and faster than those who are not. In fact‚ Gardner states that “Motivation involves four aspects‚ a goal‚ effortful behaviour‚ a desire to attain the goal and favourable attitudes toward the activity in question” (1985‚ p. 50‚ in Gass S. and Selinker L.‚ p. 350).

The Idea of Mill ’s ethical theory is his Greatest Happiness Principle in that “actions are right in proportion as they tend to promote happiness and they are wrong as they tend to produce the reverse of happiness. Happiness is the intended pleasure and the absence of pain. Unhappiness is the pain and the lack of pleasure. Pleasure and freedom from pain are the only desirable things.” Mill ’s view of happiness is hedonistic‚ which suggests that the only good thing in a person is pleasure and the
