JulsSmile [24]

Answer:

b. diffusion and osmosis across semi-permeable membranes

Explanation:

ATP (adenosine triphosphate) is a high energy carrying molecule in the system of living organisms. It posseses the ability to store and release energy for use by organisms during biochemical activities. However, some processes do not require ATP to occur and are called PASSIVE TRANSPORT while those that require energy (ATP) are called ACTIVE TRANSPORT.

In the above options, the processes listed as follows require ATP to occur:

- The active transport of glucose from the small intestine to the blood

- The movement of the flagella of sperm for motility

- Exocytosis of waste substances across a semi-permeable membrane

However, the diffusion and osmosis across semi-permeable membranes, which is a passive transport does not require ATP.

ValentinkaMS [17]

Answer:

S phase

Explanation:

The S is short for synthesis, which means that DNA is being replicated.  This is one of the stages of interphase, when the cell is growing and getting ready to divide.  Well, this is the getting ready to divide part of interphase; the cell needs to duplicate its DNA so it has enough to divide out to daughter cells.
