Fertilizer contains different types of phosphates and nitrates. When they are used to fertilize large fields, it can be beneficial in the matter of food production. But when it rains those nitrates, phosphates, etc can run off into a river,lake,stream and cause eutrophication . 

Eutrophication causes an abundance of plant growth such as algae blooms. Algae blooms can suffocate fish and can have an impact on human health.

The answer is C.

The man’s genotype must be AB. The woman’s genotype can be either BB or BO as both correspond to a blood type (which is a phenotype) of B.

Each parent passes on one allele. The man can contribute A or B and the woman can contribute B or O.

The possible genotype combinations are therefore AB, AO, BB, and BO. These correspond to the phenotypes AB, A, B, and B.

There is the biomass pyramid too, that represents the amount of mass present in the organisms of the food chain.

Eric and dawn are discussing drug distribution in the body. eric says that a drug travels from the absorption site to the bloods
Nuetrik [128]
Dawn is correct. 

When drugs are absorbed, it goes into the blood stream plasma. From there it will first go into the interstitial fluid. It will accumulate in the interstitial fluid and cross the membrane of the cell, then to the tissues, and lastly the organs.
