Answer: C) The benthic invertebrates would decrease in population size because they are eaten by the sea ducks and the phytoplankton would increase in population size.

Explanation:

The benthic invertebrates are eaten by sea ducks. Sea ducks are eaten by bald eagles. If the bald eagle was removed, there would be more sea ducks because they will have no more predators. Since there are more sea ducks, they will need to eat more food, like benthic invertebrates. The benthic invertebrates would have a lower population because the sea ducks eat more of them.

Why not the other answers:

A) The bivalves would not increase in population size. Without the bald eagle preying on sea ducks, there would be more sea ducks, who need to eat more food, such as eating more bivalves.

The phytoplankton would not decrease. With sea ducks eating more food, more benthic invertebrates are eaten. There would be less benthic invertebrates to eat phytoplankton.

B) Tundra swans were never eaten by bald eagles. There is no arrow connecting them.

D) Wading birds were never eaten by ospreys. There is no arrow connecting them.

During the light reactions, the pigments and proteins of ____________ use light to send energized electrons through an electron
Nataly [62]

Answer:

The correct answer is - photosystem II; ATP; water; oxygen

Explanation:

The photosynthesis process involves two different cycles known as the light reaction and the dark reaction. In light reaction there are two photosystems; photosystem I and photosystem II.

During light reaction, there are several pigments such as chlorophyll a and other pigments present in photosystem II that trap the light and transfer excited electrons through ETC to produce ATP which is a form of energy used by cells.

A water molecule takes place of the excited electron that is transferred and releases oxygen as waste or byproduct in this reaction.

Which allele for human blood type is recessive?
sergij07 [2.7K]

Blood type doesn't fall into the category of dominant/recessive genes exactly; rather it combines this with the properties of incomplete dominance. Ignoring the Rh factor, there are 3 alleles for blood type, I^a,I^b, and i. You will be type A if you have I^a I^a or I^a i and type B if you have I^b I^b or I^b i. You can also get type AB by having the combination I^a I^b or be type O if you have i i. If you need to use dominant/recessive, you can say the A and B allele are dominant over the O allele and codominant with one another.
