Control group
Explanation:
Experiments are usually designed so that the differences between the experiment and control groups can be observed.
- The experimental group is the group that follows the details of the hypothesis where variables are changed to see their causes and effects.
- The control group is the standard by which the experimental group is compared with.
- The variables are being tested for in the experimental group to see how they are changing .

Answer: It is A
Explanation: It is A because the television gives off light and sometimes that could heat up the tv and it is sound because obviously television makes sounds because of the volume :) hopefully that helps.
<h2><u>Answer</u> :</h2>
The correct option is A. If a dominant allele is present, the recessive allele won’t be seen.
The dominant allele is the one which appear, and the recessive one isn't shown.
For example - If a person has 2 alleles of eye colour as B ( black ) and b ( brown ), in which black is dominant and the brown one is recessive, then the person will have black eye colour because only dominant allele shows its characteristics.

If I'm not mistaken, it leaves through the osculum which is a cavity located on the upper part of a sponge.
Sponges feed through a process called filtration, which means that they filter the water in search of nutrients. And after they collect everything they need from the water, they need to let it out somehow; through the osculum.
