marissa [1.9K]
A would decrease the need for reproduction, so that's not it.
C wouldn't be helpful - less food wouldn't want you to produce more organisms, it would mean more competition for less food
D wouldn't be helpful, asexual reproduction creates a limited gene pool that is less likely to be resistant to diseases
So B is the answer, because the more of the species there are, the greater chance of survival.

What process produces most of the nadh that contributes to atp synthesis in the cell?.
IRINA_888 [86]

Glucose enters the cell during the glycolysis process. Two pyruvate, which are required for the following step, are produced by the cell after it passes it via a series of chemical processes. Furthermore, it produces two ATP and two NADH, which are then transported to the mitochondria.

<h3>What activity causes the majority of the cell's ATP production?</h3>

About thirty-two ATP molecules are produced for every oxidised glucose molecule during cellular respiration, which takes place mostly in the mitochondrial matrix.

The citric acid cycle, the second stage of aerobic cellular respiration, is the mechanism responsible for the production of both NADH and FADH2. Glycolysis, the citric acid cycle, and the electron transport chain are the three basic processes that make up aerobic cellular respiration.

ATP is generated during the glycolysis phase.

When you drink sea water, what type of solution do you expose your cells to?
Alex Ar [27]
The answer should be 1, hypertonic. 

Seawater is highly concentrated in salt, and with that being said, it has a low concentration of water molecules. 

Hypertonic means the solution has a lower water concentration than the other side (cell), vice versa for hypotonic, a high water concentration than the other side of the solution, and for isotonic, it means that both sides of the solution have the same water concentration. 

So, the answer should be 1, hypertonic. 

In addition, when your cells are exposed to hypertonic solution, the water molecules in your cells will start flowing out of the cells, to the outside, due to the difference in water concentration leading to osmosis. Your cells will lose so much water that they may even shrink!
