Large molecules enter the cell by endocytosis and exit the cell by exocytosis. Structure “A” facilitates, or helps, the diffusion of glucose across the membrane. In facilitated diffusion, molecules that cannot directly diffuse across the membrane pass through structure “A”. A. Facilitated diffusion does not require any use of cell’s energy.

B. Osmosis through structure “A” requires use of the cell’s energy

C. Active transport through structure “A” does not require use of the cell’s energy.

D. Diffusion through structure “A” requires energy.

The cell membrane is an extremely pliable structure composed primarily of ... A hydrophobic molecule (or region of a molecule) repels and is repelled by water. ... As a result, oxygen will diffuse from the interstitial fluid directly through the lipid ... (a) Facilitated diffusion of substances crossing the cell (plasma) membrane .

Explanation:

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
