Answer:
Negative feedback
Explanation:
Feedback mechanism is activated due to the change in the system that result into an output.
A negative feedback mechanism is a pathway that is caused by deviation in the output that result in a change in output direction which is usually opposite to the initial deviation.
The process of feeding of sea lamprey on the fish started as a normal pathway the deviation started when they could not feed on the fish again as a result of reduced population and they start dying of hunger. It is a negative feedback
The image shows the phase of cell division called telophase II.
<h3>What is Telophase II?</h3>
It is the last phase of mitosis, the sister chromatids separate, the chromosomes decondense, the achromatic spindle breaks down and the karyotheca, and consequently the nucleoli, reappear. With cytokinesis, in telophase I two daughter cells are formed and continue in the process of division until telophase II.
In this case, we can see in the image that the chromosomes decondense so we have telophase II.
