1. Shown in the table below are the antigens present on the blood cells of four different people. Fill in the corresponding ABO blood type for each person and the antibodies expected to be found in each person's
blood.
Blood Type
Red Cell Antigen
Antibody in Blood Plasma
A
B
AB
Neither
2. For each blood type in the table below, fill in the expected platination result yes ar no) tramming the
blood with each of the antibodies

true is the final answer!

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."

i think it’s c but i might be wrong. if i am let me know! have a good rest of your day as well!

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
