Large molecules often cross the plasma membrane while inside vesicles.
Explanation:
The plasma membrane is a fluid membrane mad of phospholipids bilayer. The fatty acid chains are sandwiched in between the phosphate ends of the lipid layers. The fluidity of the membrane is due to the fact that these molecules, including the integral proteins that span the membrane are NOT covalently bound to each other hence can freely move within the membrane. Cholesterol molecules are intercalated in between the fatty acid chains and prevent these carbon chains from binding to each other tightly through hydrogen bonding hence adding to the fluidity of the membrane. The cell membrane has natural pores within it that allow small molecules such as water to pass through, passively, in and out of the cell. Larger molecules have to pass through channels created by the integral proteins while the largest molecules are taken in by endocytosis and taken out by exocytosis, which translates to vesicle transport in cell.

Answer:
mixing chemicals together
Explanation:
eating and drinking
Answer:
Both depends on different factors.
Explanation:
The rate of movement of the air bubble is not exactly the same as the rate of water loss from the plant because both depends on different environmental factors. The higher rate of movement of the air bubble occurs due to removal of pressure while on the other hand, the rate of water loss from the plant occurs due to temperature. So both air bubble and transpiration process depends on different environmental factors.
Plasma membrane, Ribosomes, cytoplasm, and DNA.
Photosynthesis, how plants survive. Sunlight is absorbed.
