In some types of research the target population might be as broad as all humans, but in other types of research the target population might be a smaller group such as teenagers, pre-school children or people who misuse drugs.
It is more or less impossible to study every single person in a target population so psychologists select a sample or sub-group of the population that is likely to be representative of the target population we are interested in.
This is important because we want to generalize from the sample to target population. The more representative the sample, the more confident the researcher can be that the results can be generalized to the target population.
One of the problems that can occur when selecting a sample from a target population is sampling bias. Sampling bias refers to situations where the sample does not reflect the characteristics of the target population.
Gravitropism or geotropism which is a growth response to gravity
a growth response to light is called phototropism
In commensalism, one organism benefits from the relationship while the other species involved neither benefits nor is harmed. The benefits for one organism can be in a variety of forms, including food, shelter, transportation and seed dispersal.
3. In the sim molecules moved faster when it was warm and slower when it was cold. This can explain why the food coloring spread faster in warm water because the molecules were moving faster causing the food coloring to quickly spread through out the water.
