Colt1911 [192]3 years ago
4 0
In a controlled experiment, there are two groups. The control group is a group that nothing happens to. The experimental group is the group that you subject to the variable with which you are experimenting. At the end of the experiment, you test the differences between the control group, for whom nothing happened, and the experimental group, which received the variable. The difference (or similarities) between the two groups is how your results are measured.
A control group is the group used for comparison in an experiment. One group receives the treatment that is being tested by the experiment; another group (the control group) has the exact same controlled environment, but does not receive this treatment. The effectiveness of the treatment can then be established by comparison with the control group.

Speciation is the formation of new species as result of evolution by natural selection. What effect could separation of populati
vagabundo [1.1K]
<span>Animals pass down their features to their children when they breed.  </span>When you separate a population (or group of animals of the same species), say by building a large wall, they can't interbreed with each other.  This means that if an animal on one side of the border gets an adaptation, it won't pass it on to the other animal.  Soon, each side will evolve different adaptations, and the two populations will become so different that they become two different species.

It is possible that one-half wouldn't be able to survive, and go extinct, but it doesn't happen all the time (A is incorrect).  Similarly, the populations don't ALWAYS evolve into two different species, though they may (B is incorrect).  However, if the environments differ enough, they will acquire different adaptations through evolution.  C is correct!  Keep in mind that D is incorrect: the first part, the populations can't interbreed, is correct, but that doesn't mean they will die off.
