Materials move within the cell 's cytosol by diffusion, and certain materials move through the plasma membrane by diffusion. ... Diffusion: Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm). Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.The cell membrane controls what goes in and out by having protein channels that act like funnels in some cases and pumps in other cases. ... Active transport requires energy, because protein machines actively grab molecules on one side of the membrane and push them through to the other side
Answer:
Most cells of adult mammals spend about 24 hours in interphase; this accounts for about 90%-96% of the total time involved in cell division. Interphase includes G1, S, and G2 phases. Mitosis and cytokinesis, however, are separate from interphase
Answer:
Both are Homozygous
Explanation:
A Husband and Wife with curly haired husband(CC) and straight haired wife have all their children curly haired because the gene for curly hair is dominant than straight hair. So, in the progeny, curly hair only.
This represents the Mendel’s Law of dominance which is also the Mendel Third Law which states that one of the factors for a pair of inherited traits will be dominant and the other recessive, unless both factors are recessive.
So, the correct option is ‘Both are homozygous'.
The correct option is C.
From the information given above, it can be seen that, the caterpillar is a predator of the lupine plant. In order to ensure successful succession in the environment, the best thing to do is to increase the density of growth of the lupine plant, so that there will still be enough lupine plant to enrich the soil even though the caterpillar is feeding on them.
