D
Nitrogen became a selection pressure.

A male pistol shrimp with protective eye tissue pockets mates with a female shrimp without protective eye tissue pockets. All of the offspring have eye tissue pockets. What is the most reasonable conclusion that can be made about the eye tissue pocket trait in pistol shrimp?
1Points
A
It is a recessive, autosomal trait.
B
It is a dominant, autosomal trait.
C
It is a trait that results from multiple alleles.
D
It is a trait that results from incomplete dominance.
I know only the last one and I think it’s B cause dominant trait is the trait observed in the first generation when parent with different traits are bred like Mendel’s first experiment

that's just the answer lol
Answer:
For number 5 the correct answer is B.
Explanation: Interphase is not part of the four stages of mitosis. It is part of the cell cycle which consist of: Interphase, Mitosis, and Cytokinesis.
Respiration- only after meal . Only active process is involved
Cellular- Production of ATP via oxidation of organic sugar compounds
I hope this helps :)
3. Nutrients are produced by phytoplankton living in these zones.
4.Nutrients are produced by zooplankton living in these zones
The answer is; 1
Most of the photosynthetic organisms are located in the epipelagic zone of the oceans where sunlight can penetrate before diffusing and becoming too weak to support photosynthesis. The epipelagic zone is filled with plankton. When this plantkon die, they begin to sink slowly to the bottom of the ocean. These plankton are food for small fish. These small fish are food for bigger fishes. This is how an ecosystem is sustained in the deep dark oceans.
