Elenna [48]
The correct answers are no movement; extensive movement.
You cannot move the joints near your skull - at least now willingly - only a doctor can remove parts of your skull if you are undergoing a brain surgery. Otherwise, there is no movement at all there. However, when it comes to your shoulders, for example, you can move them at will in whichever way you want to.

Which substance on the plasma membrane helps identify chemical signals from outside the cell?
cluponka [151]

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.
