Answer:pretest/posttest

Explanation:

A pretest-posttest refers to a experiment in which individuals in a study participate before and after the experiment. This is done so that a researcher may examine if manipulation of the experiment changes the result obtained from the participants. In this design there is only one large group used for the experiment.

This is done to examine and establish if changing something can influence the participants. The manipulation is constant throughout all the participants since the participants are studied before and then after the manipulation of the experiment.

Sati [7]

Answer:

Interspecific interaction are close interactions between species that have evolved over long periods of time. When these interactions enhance the reproduction and population growth of both species, they are called symbiosis.

Explanation:

In nature, there is a wide range of examples of mutually beneficial symbiosis - from gastric and intestinal bacteria, without which digestion would be impossible, to plants (often orchids), whose pollen can be spread by only one, a certain type of insect. Such relationships are always successful when they increase the chances of both partners to survive. The actions or substances produced during symbiosis are essential and indispensable for partners. In a generalized sense, such a symbiosis is an intermediate link between interaction and fusion.
