Facilitated diffusion is the process by which molecules move across the plasma membrane with the aid of membrane proteins like channels and carriers. These molecules move down a concentration gradient, which gives them the potential to diffuse into (or out of) the cell.
Passive transport is a subset of facilitated diffusion. Because the solution is travelling down the concentration gradient, assisted diffusion is still passive transport even when it incorporates transport proteins. The cell membrane can easily be traversed by small, nonpolar substances.image outcome.A case of enhanced diffusion is glucose transfer. The lipid bilayer of the membrane prevents glucose from passing through since it is a big, polar molecule. In order to pass through, it requires carriers known as glucose transporters.

Answer:
C
Explanation:
The Calvin cycle occurs in three major phases:
1) Carbon fixation; which involves the reaction of CO2 with a phosphorylated Co2 acceptor called Ribulosebiphosphate(RuBp) as catalysed by Rubisco enzyme. Due to the instability of the formed six-carbon compound, it breaks into two molecules of 3-phosphoglycerate (PGA)
2) Reduction; The PGA is phosphorylated by ATP to form 1,3-biphosphoglycerate, which is then reduced by NADPH to form glyceraldehyde-3-phosphate (G3P).
3) Regeneration; The final step, which is very important for the continuity of Calvin cycle is the regeneration of the CO2 acceptor (RUBP). The molecules of G3P are rearranged into molecules of Ribulosephosphate(RuP) by series of complex reactions, which is then phosphorylated by ATP to form RUBP, ready to accept CO2 for the cycle to continue
Answer: I think it wants you to collect information on US hurricanes, and also collect information on Typhoons/cyclones that hit Asia. Since I don't think hurricanes happen in Asia. And a US hurricane would definitely not reach Asia. Oh and the word 'hurricane' isn't used to describe the typhoons/cyclones that happen in Asia.
