We use samples to perform experiments. When sampling, we take test subjects from a larger group often known as "<em>population</em>" or at times "<em>universe</em>".
Sampling is a term we use to describe the process of selecting a small representitive group from a larger population. Sampling can often be divided in its simplest form into:
- <u>Random Samples</u>
- <u>Non-Random Samples.</u>
Which as their names imply, represent first a sample that is chosen by not specific method and whose probability is equal for the entire <em>population</em>, and secondly a sample chosen based on specific parameters.
Sampling can then become more complex, being divided into more complex methods such as:
- <u>Systematic sampling
</u>
- <u>Stratified sampling
</u>
- <u>Cluster sampling</u>
etc.
The one thing all of the sampling methods have in common is the fact that they will all draw their samples from one place. This place or aspect from which samples are drawn is known as the <em>population</em> <em>group </em>or sometimes coined as the <em>universe</em>, to represent the group in its entirety.

Melanophores are small pigments that are present in the dermis layer of the skin of a shark. They impart a gray color to the dorsal and lateral surface area of the shark. They help in background adaptation and countershading of the body, which makes a shark difficult to be seen.
Answer;
C) decreasing the concentration of an enzyme
Explanation;
-Environment factors such as temperature and pH affects the activity of an enzyme. Changing these conditions alters the rate of the reaction caused by the enzyme.
-Each enzyme works at certain optimal conditions such as optimal temperature and optimal pH, thus increasing temperature and pH to optimal levels will increase the rate of enzyme reaction.
-Changing the concentration of enzyme and substrate will also affect the rate of reaction of an enzyme-catalyzed reaction. Increasing enzyme concentration increases the rate of enzyme activity.
