Exam: 46.4‚45‚47‚48 Lecture outline for the zoology unit revised 2010 Introduction to animal form & function and regulation of TB (ch. 40 & Concept 42.4) This first reading assignment reviews 5 major principles re living organisms: 1. Physical laws & the environment constrain the size & shape of organisms. 2. Form & function are correlated at all levels of organization. 3. Chemical energy in food is used to sustain form & function. 4. Many animals (& other organisms) regulate

Polymers have different structures. They also have different functions. Describe how the structures of different polymers relate to their function? Polymers a large molecules made up of a chain of smaller molecules‚ known as monomers. The monomers that a polymer is made up of decide its structure and therefore it’s function. These monomers are linked and coiled in a very specific manor giving the polymer a specific tertiary structure (an extensively coiled and linked polymer chain caused as a

Does not cause coronary heart disease It cannot be digested E i) 2 hours ii) stomach It has an acid resistant coat‚ hence the acid in the stomach will not be able to dissolve its coat and the drug will not be released. It also has a permeable coat which tends to stick to the mucus‚ hence it will move down the alimentary

Unit 5 Outcome 2 – Energy Metabolism Booklet The Respiratory System The respiratory system consists of the nose‚ mouth‚ pharynx‚ larynx‚ trachea‚ bronchi and lungs. These provide a passageway to allow air in and out of the body. Every cell in the body requires oxygen to survive. The primary function of the respiratory system is the exchange of gases. The respiratory system allows oxygen and carbon dioxide exchange‚ this is necessary to sustain life. During the process of breathing air is inhaled
