the answer is Life Science
active transport in small intestines and passive transport in blood cells
The correct answer is A.
Toxins and various pollutants increase in concentration through the food chain in a process called biomagnification. This means that the organisms on the top of the food chain, like the herring gull, have many times greater concentration of toxins than the lower food chain level organisms because they prey on lower food chain level organisms. If a herring gull ears 100 herrings, it will have a 100x times greater concentration of toxins in its body than a herring.
White flowers would be recessive and purple would be dominant
(ps capital letters show the dominant genes and lowercase are usually the recessive)
