I’m not sure I think it’s c tho
I believe it’s A. Active transport is the opposite of diffusion. Diffusion is trying to get from a high to a low concentration gradient. Active transport uses energy to get particles from a low concentrated gradient to a higher concentrated gradient. This is most commonly used in digestion. Some nutrients are actively transported from the gut to the blood which is vital for us humans to not starve.

10. Explain Darwin's theory. You can us
use diagrams to help you.

Answers

Darwin’s theory of evolution explains that evolution occurs from natural selection.

Individuals from each species each have a certain set of physical traits.

One individual will have a set of traits that is more suited for their environment and will survive (where as the less suited ones will not) and very very slowly overtime that particular species will evolve into another species, or evolve.

Darwin’s point was that basically, every species that is alive today was not “created” individually, but evolved from simple life forms to more complex and diverse life forms.

Answer: 10. Control Group

11. Identify the:

Control Group = Subject A

Independent Variable = The new and original itching powder.

Dependent Variable = The type of itchiness.

Explanation: The Control Group is NOT affected by the experiment. Subject A was given the original itching powder and is not being experimented on with the new itching powder, therefore, Subject A is the Control Group.

The Independent Variable is what you can CHANGE. You control the two itching powders, so you decide which one you give to who. This makes the two itching powders the Independent Variable.

The Dependent Variable DEPENDS on the effects of the Independent Variable. This is what you cannot change, the results. In this case, the type of itchiness experienced and the amount of itchiness experienced cannot be changed, it is a result of the powders, hence why it is the Dependent Variable.
