Answer:
The control group is the 15 young hemlocks trees with fencing around them to prevent deer from eating them.
Explanation:
An experiment is designed to test one or more hypotheses. For that, you need control and treatment groups. The control group is the non-effect group, it is the one from which you compare results from the treatment group. On the other hand, the treatment group is the effect group, it is the one that will be exposed to the "thing" that you want to test the effect of. Because you want to evaluate the impact of deers on the young hemlocks trees, the control should exclude deers.
In this case:
Hypothesis: Because deers eat young hemlocks trees and the population of deer had doubled in the last five years, the mature hemlocks trees are more abundant than the young hemlocks trees.
Control: group of 15 young hemlocks trees with fencing around them to prevent deer from eating them.
Treatment: a group of 15 young hemlocks trees with no fencing around them to permit deer eating them.

Lipophilic hormones,
intuitive as the name suggests, tend to dissolve
well in lipids/fats than they do in water. Therefore lipophilic hormone does not dissolve well in blood plasma which
would affect their diffusion. The carrier proteins are mainly the serum
albumins.

Answer:
A familiar example of homeostatic regulation in a mechanical system is the action of a thermostat, a machine that regulates room temperature.
Explanation:
Answer:
Water is a fluid with a high specific heat.
Explanation:
Specific heat is defined as the amount of heat energy measured in calories, that is required to change the temperature of one gram of a substance by one degree Celsius. Water has a very high specific heat of 4.184 Joules. This means that water does not get heated up or cooled easily.
This is important for earth's climate and the organisms in it as they are not subject to sudden and frequent temperature fluctuations.
