The proper response is "yes, yes, no" or "B, B, A".
Clarification:
In this hypothetical situation, an inhibitor obstructs the function of motor proteins in the kinetochore while still allowing the kinetochore to stay attached to the spindle. The animal cells treated with this inhibitor can elongate during mitosis, leading to the separation of sister chromatids, but the chromosomes will remain still instead of moving to the poles of the cell. The only action the inhibitor affects is the motor protein function, which is responsible for the movement of chromosomes to the poles during cell mitosis.
A gene is a segment of DNA that typically contains the code for a particular protein influencing a specific trait, while an allele is a segment (a version) of that gene. The correct choice among the options is option "D".
In a lake, oxygenic phototrophs generate new organic materials and oxygen. If the primary production rates are overly high, the resulting surplus of organic matter can deplete oxygen levels in the bottom water due to respiration, leading to anoxic conditions, which then promotes anaerobic processes such as anaerobic respiration and fermentation. Organic matter that remains unconsumed in the surface layers sinks and is broken down by anaerobic organisms.
