Answer:

The cytoplasm probably.

Explanation:

If there was cell membrane as an option, I would probably select cell membrane as the answer instead. The cell wall is fully permeable hence does not play a role in maintaining cell homeostasis, but rather plays a role in structural integrity of a plant cell. The mitochondria provides energy for cellular processes, not so much of maintaining cell homeostasis. The cytoplasm maintains a constant environment for cellular processes to take place hence would be the best answer out of all the three.

Answer:

a. It's a carrier protein doing facillitated diffusion

Explanation:

Facilitated diffusion may be defined as the transportation of molecules from a high concentration to a low concentration that is down the concentration gradient without input of the energy. Whereas the active transport is transportation of the molecules from the low concentration to the high concentration which is against concentration gradient by the membrane protein.

The glucose transportation process requires membrane protein for the transport and does not require any energy. Therefore, it is carrier protein which is doing the facilitated diffusion.

<h3>Gel electrophoresis and DNA fragments</h3>

Gel electrophoresis is a method to separate DNA fragments (or RNA and other macromolecules) based on their size and charge, involving a gel called agarose. The molecules will travel through the gel at different speeds or in different directions, which allows them to be separated from each other.

Because all DNA molecules have the same amount of charge per mass, gel electrophoresis of DNA fragments separates DNA molecules based on size only. Shorter pieces of DNA travel through the pores of the gel more quickly than longer ones do.
