Which form of cell transport allows small molecules to move from an area of higher concentration to an area of lower concentration without energy being required from the cell?a. osmosis
b. pinocytosis
c. phagocytosis
d. simple diffusion

Answers

Answer 1

Answer: Osmosis is the movement of small molecules from an area of higherconcentration to an area of lower concentration without energy being requiredfrom the cell. It only uses the difference in concentration of the surroundingmolecule. The answer is letter A. It is not a simple diffusion because thestatement above is in the form of cellular transport. It is not phagocytosis becausephagocytosis is the process by which a protest or phagocyte engulfs a solidparticle to form phagosome. It is not pinocytosis beacasue it is a form of celldrinking wherein small particles are brought into the cell and then suspendedwithin the vesicle.

Answer:

Carbon is found in all living organisms. The constant flow of carbon on Earth through organisms and the air is known as the carbon cycle.

Plants absorb carbon from the atmosphere in the form of carbon dioxide. They use it for respiration and photosynthesis.

Animals consume plants, transferring carbon along the food chain. Plants and animals respire and release carbon into the air. When the animals and plants die, they are eaten by decomposers.

Carbon enters back into the atmosphere in the form of carbon dioxide through the process of decomposition and combustion.
