Answer: C, chromosome replication
Explanation:
A, B, and D only occur in meiosis, as crossing over is required for genetic variation, which isn't needed in mitosis, reduction division is when diploids are reduced to haploids, which only happens in meiosis, and homologous chromosomes making tetras doesn't occur in mitosis either. However, during interphase of both mitosis and meiosis, chromosomes (DNA more specifically) are replicated.
The nervous system helps:
Receptors in muscles provide the brain with information about body position and movement.
The brain controls the contraction of skeletal muscle.
The nervous system regulates the speed at which food moves through the digestive tract.
The nervous system regulates respiratory rate
The nervous system regulates heart rate and blood pressure.

Answer:
Hypothesis is ''With the increase of algae in the aquarium, fish population decreases''.
Explanation:
The main problem was that there is no need for 2 aquarium because there is no need for aquarium 1 which has no fish and aquarium 2 which has fishes but no algae. With the increase of algae in the aquarium, fish population decreases is the hypothesis for this experiment. Concentration of algae is the independent variable of the experiment because there is no effect on it in the experiment.
