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

Organisational structures Organisational structures Fig. 1: Large organisations tend to follow this type of structure An organisational structure consists of the levels of management and division of responsibilities within an organisation. Organisational structures show all the roles and types of jobs within an organisation. A complete organisational structure will show each type of position and how many of these there are at present. When smaller organisations look at their organisational

necessary for cellular respiration‚ and to dispose of CO2‚ a bi product of respiration. An efficient gas exchange system has 3 requirements. It must have a large surface area over which the gases can diffuse. A large surface area maximises the amount of area available for the gases to exchange. It must also be moist. Oxygen must first dissolve into a fluid before it can diffuse into a cell. Having a moist gas exchange surface ensures the gases can be dissolved. Thirdly‚ the membrane through which gases diffuse

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
