Answer: B
Explanation:
The nutrients that wash off of the continents (waste products, sediment) are often rich in essential minerals to plankton and other microscopic aquatic life, which in turn are the base of the marine food chain.
Tsunamis are too infrequent and do not dredge up any sediment most of the time, and C is not correct because nutrients don't just rain from the sky.
Cytochalasin D prevents the addition of monomers at plus ends of existing filaments. When the concentration of G-actin in the cytosol is below the critical concentration, the loss of monomers at <span>minus ends</span> of existing filaments eventually results in their shortening. This occurs despite the pool of available G-actin in the cytosol.
Answer:
The correct answer is A. pollen.
Explanation:
Pollen is a very efficient way to colonize and reach further. It's believed that this adaptation is the main reason why land plants could colonize so many environments. The fact that pollen is little and easily transported also was very important.
The skin, mucous membranes, and endothelia throughout the body serve as physical barriers that prevent microbes from reaching potential sites of infection. Tight cell junctions in these tissues prevent microbes from passing through.
