The correct answer is letter A, the increased nitrates from the fertilizers leech into the water and cause algal blooms, which take oxygen out of the water and this suffocates fish.
This is one of the many chain reactions that agricultural farming brings to the environment, and it will be very common through the years as people have not figured out a safer way to protect crops.
Answer:
"The smallpox vaccine does not contain smallpox virus and cannot spread or cause smallpox. However, the vaccine does contain another virus called vaccinia which is live in the vaccine. Because the virus is alive, it can spread to other parts of the body or to other people from the vaccine site."

Carbon dioxide is not safe for your lungs because once it reaches your lungs it will stop your breathing and you could die.
"Water quality" may include the amounts of dissolved oxygen
and the levels of algal growth, pollutants which may be present and the pH level. Water quality effects also which types of organisms can
survive in a body of water.
Shellfish require a high level
of dissolved oxygen and their abundance is an indication of good water quality. Shellfish are sensitive to changes in the ecosystem and they cannot easily escape changes in the water quality. These are one of the reasons why shellfish are good indicators of water quality.
Answer:
Covering organs within trunk cavities
Lining trunk cavities
Explanation:
Serous membranes are layers of tissue that protect the organs. They prevent the organs from getting damage from friction which can occur as they rub against the cavity walls.
Serous membranes have two layers, the visceral layer and the parietal layer. The visceral layer covers the organs while the parietal layer covers or lines the cavity walls. In between these two layers, you will find a gap or cavity filled with serous fluid.
They cover organs like the heart, lungs, blood vessels (some of them at least), testes and other organs found in the abdominal cavity.
