First pic :
plants do not have cell membranes
(plants have BOTH cell membranes and cell walls)
second pic:
ATGC
(opposite strand of the DNA TACG)
third pic:
the second choice
(selectively permeable means only specific molecules could get in and go out)
fourth pic:
option 2
(cellular respiration takes sugar (or food) and makes it into ATP energy. this is what makes us have energy after we eat)
I really hope this helped :))
Microtubule – serves as a framework of the cell –cytoskeleton.<span>
</span>
Nucleus – the control center of each cell. It regulates, monitors and organizes the whole cell<span>
Since the pictures isn't given I can assume that it can be the microtubule, the microtubule is responsible for maintaing the shape and structure of the overall cell. It maintains homeostasis by permanently aiding the framework of the overall cell.
If it is the nucleus, the control center of a cell. It does a lot of functions in the cell, it helps maintain homeostasis by sending commands that the organelles do, supply energy, excrete or digest waste, regulate the movement of objects and cellular respiration, even cell division. It sustains the cell to be functional and proactive at the same time reactive to situations that is likely to occur.

i think answer is D animal in the rain forest
Answer: D, all are processes that shape Earth's features. I don't know if this was a choice answer but, hope this helps. :)
Explanation:
<u>Answer</u>:
Substance A affects the amount of the activation energy needed by the process by catalyzing the reaction. Enzymes are the natural biological catalyst that lowers the activation energy for a reaction to proceed faster at a low energy requirement.
<u>Explanation</u>:
The reactants in the solution react to form a product. For a reaction to happen some energy is needed. The energy which helps reactants to break some bonds and make other bonds to make a product is known as activation energy.
Enzymes are the biological molecules which lower this activation energy by catalyzing the reaction by helping in breaking old bonds and forming new bonds to create a product.
