Answer:
all the organisms living in an area that have the potential to interact
Explanation:
D. the process of cell growth
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made up of protein and a single molecule of deoxyribonucleic acid (DNA).
The unique structure of chromosomes keeps DNA tightly wrapped around spool- like proteins, called histones. Without this kind of packaging, DNA molecules would be too long to fit inside the cells.
DNA molecules in a single human cell if unwound from their histones and placed end to end, they would measure 6 feet in length.
Chromosomes play a key part in ensuring that DNA is accurately copied and distributed to new daughter cells as the parent cell divides to form new cells.
The process that is non-functioning in the person with diabetes is negative feedback mechanism. The correct option is B.
<h3>What is negative feedback mechanism?</h3>
A self-regulating system is a negative feedback loop, also known as an inhibitory loop. Increased output from the system inhibits future production in a negative feedback loop.
When blood glucose levels are too low, the pancreas secretes the hormone glucagon. This travels to the liver in the blood and causes glycogen to be broken down into glucose.
When glucose enters the bloodstream, glucose levels return to normal. This is an illustration of negative feedback.
Thus, the correct option is B.
