Question

question 7
the plasma membrane not only provides a protective barrier for the cell but also determines which substances enter or exit the cell. we call this characteristic:
selectively permeable
active transport
osmosis
diffusion
membrane potential
question 9
0 / 1 point
the type of membrane transport in which large molecules are moved into cells using vesicles is called:
diffusion
facilitated diffusion
active transport
osmosis
endocytosis

Explanation:

For Question 7, the plasma membrane's property of allowing certain substances to pass while restricting others is called selectively permeable. Active transport is a process of moving substances against a concentration gradient using energy. Osmosis is the diffusion of water across a semi - permeable membrane. Diffusion is the movement of substances from high to low concentration. Membrane potential is related to the electrical charge difference across the membrane.
For Question 9, diffusion is the movement of substances from high to low concentration without using vesicles. Facilitated diffusion uses transport proteins but not vesicles. Active transport moves substances against a concentration gradient using energy and not vesicles for large - molecule entry. Osmosis is water movement. Endocytosis is the process where large molecules are moved into cells using vesicles.

Answer:

Question 7: selectively permeable
Question 9: endocytosis
