Which factor distinguishes the experimental group from the control group
AysviL [449]
A control group is sort of the normal group. The group you aren't changing or messing with. It is to show what the species/experiment acts like on its own in response to something without you having to change it at all. 

With an experimental group, you are changing something about the subject before putting it in the conditions it will need to respond to. 

I don't entirely understand, but I know the control group is constant, unchanging. It sort of helps with distinguishing things. I have examples of experiments if that will help you understand what a control group is to answer the question. I also have a The Death Cure example if you have seen or read the book. I hope you do not fail this assignment, but even if I did not answer with an answer you were looking for, it could have helped you answer the question on your own. 

I saw somewhere a similar question, though I was given the answer choices. If this is the answer you are looking for: variable(s).

Control groups don't use variables because you aren't changing them.

Why does a hormone only act on specific cell types in an organism and not others?
Vilka [71]

Answer:

c) A cell must have the appropriate receptor before it can bind to the hormone.

Explanation:

Hormones are chemical signals that are secreted into the circulatory system acting as regulators within the body, and even though they can reach any part on the body, <em>only certain types of cells are equipped to respond, these cells are known as target cells, when the hormone reaches a cell with an adequate receptors it triggers a signal transduction and then a response.</em>

Therefore the correct answer is c.

I hope you find this information useful and interesting! Good luck!

In the energy pyramid below, what would most likely happen to all other levels if a disease killed off all of the rabbits? *
Pavlova-9 [17]
The answer is A. Rabbits eat grass. The snakes eat the rabbits and the hawks eat the snakes. So if rabbits died off, so would the snakes, and the hawks. Because both of their food sources would deplete. And grass would flourish.

Which of the following is NOT true about the digestive system of annelids?
lapo4ka [179]
Yes I think you are right. It does not contain setae for food to travel to the anus. But it's something else that develops the food into poop and travels through anus

Hope this helps :)
