What characteristic makes osmosis different from diffusion?

a. osmosis is used for gases, such as oxygen and carbon dioxide. diffusion is used for water that contains salt or sugar molecules.

b. osmosis occurs through a semipermeable membrane. diffusion occurs through a permeable membrane.

c. osmosis requires facilitation by an energy-carrying molecule, such as atp. diffusion requires no additional energy to move molecules across the concentration gradient.

d. net movement in osmosis is from areas of higher concentration to areas of lower concentration. net movement in diffusion occurs from areas of higher concentration to areas of lower concentration.

The Answer Is b.) Osmosis occurs through a semipermeable membrane. Diffusion occurs through a permeable membrane.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
