This is to make sure the test is reliable because it can happen that the two variables being tested affect each other skewing results

Because if we're simultaneously moving/manipulating two different variables it can be very hard to determine why one variable is changing and why the other is changing. While this can be done with more complicated experimental designs, it usually is the case that scientists will only manipulate one variable and not two different ones.

Examine how nearly all energy for life comes directly or indirectly from the sun given that heterotrophs get their energy from t

If another animal was to eat the initial consumer of the autotrophs then they would be getting the energy stored in that animal that was obtained by eating the autotrophs who had the initial energy.<span>

Carbohydrates are the primary source of energy for the human body,
Ipatiy [6.2K]

Answer:

If your body lacks enzymes that break down carbohydrates, it would be unable to get glucose molecules.

If you lacked the enzyme to digest proteins, you may not absorb enough amino acids.

Explanation:

Carbohydrates and proteins are the food materials that are used for the production of energy. Our body cannot absorb carbohydrate so it must be broken down into simpler substance such as glucose molecules by amylase, while proteins are broken down into simpler substances such as amino acids by pepsin enzyme.
