Answer:
The CORRECT ANSWER IS B.
B. Unlike the other countercurrent systems, a countercurrent multiplier system expends energy in active transport.
Explanation:
The countercurrent multiplier system involving the loop of Henle uses up energy in the form of ATP to actively conduct NaCl out of the filtrate in the upper region of the ascending limb of the loop. This energy in the form of ATP that is being used uniquely differentiates a countercurrent multiplier system from the different forms of countercurrent systems.
In gametogenesis , germinal cells multiply by mitosis and mature garnetes are formed by meiosis.
Answer:
A: Suited for their environment
Explanation:
You can automatically eliminate B and C, since they both say that animals with adaptations that won't work with their environment would have a higher survival rate. This doesn't make sense; adaptations that wouldn't suit an environment would actually lower the population's chances of reproduction and survival.
That leads us to A and D. However, A would be the correct answer. Organisms with adaptations that suited their environment would help them (since it would make the organism more compatible with their environment), rather than having no change at all.
Hope this helped!
