Answer: its B
Explanation: I answered the same thing.
Answer:
Maintaining a normal blood volume is necessary for blood to be able to adequately reach all of the tissues of your body. When you're very dehydrated, your blood volume can decrease, leading to a drop in blood pressure. When blood pressure drops too low, your organs won't receive the oxygen and nutrients they need. might be what you are looking for but if not i will change it
Explanation:
Answer:
C. Coupled reactions establish an electrochemical gradient across a membrane.
Explanation:
- During cellular respiration in mitochondria, and during photosynthesis in chloroplasts, the electron transport chain requires a proton gradient to pump protons across the membrane by active transport.
- Protons flow back across the membrane by facilitated diffusion through ATP synthase, which utilizes them to phosphorylate ADP to ATP.
- This process of ATP synthesis by harnessing the elctrochemicaal gradient geenrated by the diffusion of protons across the biological membrane through ATP synthase is called chemiosmosis.
If a mutation results in an organism with new characteristics then eventually a new species will be formed if more such mutations will continue to accumulate in the individual. Mutations result into the accumulation of variations in an individual and when such variations keep on accumulating in a particular organism consistently it leads to formation of a new species or we can say that evolution has occured.
The correct answers (c.) punctuated equilibrium.Punctuated equilibrium is a mode of evolution that the certain foraminifera (shelled protozoa) represents. It is , in fact, the hypothesis of the evolutionary development of rapid episodes that is marked between long periods of little or even with no change at all.
