For question 7, I think the answer is actually a since you want to view the surface of the cells. So you would choose to use a scanning electron microscope instead of a transmission electron microscope.
Question 13, I think is b not a. If you shake a mixture of amphipathic lipids and water, lipids will form tiny vesicles filled with water rather than separate into two distinct layers. Help me out, I am not 100% sure…
Question 16, D instead of b. Ions cannot cross planar bilayers and water cannot block the movement of ions across a membrane.
Question 18, a not b. Vegetable oil is a liquid since it has more double bonds than animal fats. Not the other way around.
I double checked and i agree with the answers you provided. Also, is it just me or can you also not see answers after question 19. I can’t see the markings.
