Answer:
Molecules naturally disperse from areas of higher concentration to lower concentration.
As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.
The mitochondria creates carbon dioxide (CO2) as a waste product of cellular respiration (the process that makes energy for your body). Because the CO2 is of a higher concentration in the cell than in the blood passing by, this gas continually diffuses out of the cell. It too is small and uncharged so it can pass through cell membranes easily.
These movements require no energy (in the form of ATP) on behalf of the cell.
Explanation:
I’m not sure I think true/false
C) ribosomes and mitochondria
Answer: A sea breeze occurs due to the difference in temperature between the ocean and the land. As land heats up during the afternoon, air above it begins to rise forming a low pressure are near the land. then cool air, situated in high pressure areas, spreads across the water and moves in over land.
Explanation:
Answer:
A) There will be less genetic variation from recombination of risk of not adapting quickly to environmental changes
Explanation:
Natural selection: It is the process of adapting a species by a natural selection in the environment by the selection to change in re productivity in geno-type. It is processed in which the genes are selected and preserved for the future. These genes are those which survival chances are more and this selection of generation to generation has been multiplied. The genetic frequency the same generation to generation. The mutation is another that leads to a change in the generation that takes a population and occurs at a very low cost.
