Answer:

<em><u>The correct option is A) carbohydrate chain</u></em>

Explanation:

The carbohydrate chain present in the cell membrane helps determine the characteristics of the cell and it also helps to identify the chemical signals from outside the cell. Hence, option A is correct.

Other options, like option B, is not correct because the function of the cholesterol in the cell membrane is to prevent the fatty acids from sticking together. Option D is not correct because transport proteins help some molecules to move inside the cell.

laiz [17]

Peter and rosemary discovered a natural ecosystem with an extreme climate, oscillating between cycles of intense drought and abundant rainfall, as well as an uncontaminated area that had never been explored by humans. This was an excellent location to study the evolution of Galapagos finches.

  • For their outstanding long-term studies showing evolution in action in Galápagos finches, Peter and Rosemary Grant are renowned.
  • They have shown that natural selection is responsible for the incredibly quick changes in body and beak size in response to variations in the availability of food.
  • Due to the lack of predators or rivals for the finches, Daphne Major makes an excellent location for research.
  • (The cactus finch is the only other finch on the island.)
  • The weather, and consequently the availability of food, has a significant impact on the medium ground finch's capacity to survive.

The process of becoming physiologically adjusted to a high elevation is called _____.
MA_775_DIABLO [31]

Answer:

C. Acclimatization

Explanation:

I think of "acclimatization" as acclimating to a new environment, also it's clearly derived from acclimating. It's just another way to say adjusting to the environment, and isn't necessarily restricted to high elevations. It could also be temperature, or humidity. I hope this helped!
