If cells do not work together, the organism would die.
Explanation:
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.
You make an educated guess in what you already know about the experiment.
Make sure you hypothesis is testable, It is not a question so dont make it sound like one <span />
Gorillas are a predator. They eat food and rarely ever get killed for food. But if we take away their habitat by making buildings and houses then they will die for other causes like hunger. If the gorillas go extinct then the food change will get all messed up. The food they normally eat will over populate meaning the food gorillas eat (like fruit) will over populates and take over the area. That means it will start to take up the space that other plants need to grow. The other plants that other animals will need to eat will slowly start moving away because their food is dying. They will start to go somewhere else and mess up that habitat too. Those animals will eat the food needed by the animals that lived there originally and food will become scarce for animals that all need the same type of resources.
