Answer: D. a fertilized egg cell
Totipotent stem cells are cells which are formed when a sperm fertilizes a egg resulting in a zygote. A zygote being a totipotent stem cell divides many times to develop specialized cells in a new human being. Therefore, a fertilized egg cell has greatest number of totipotent stem cells.
Answer:
It varies greatly...
Explanation:
(a) Latitude is one of the main factors that pushes the evolution toward adaption to a environment. For example, at higher latitude, the diversity is a little low than on lower or average latitude due to the availability of resources that are easily available on ground level relatively.
(b) As we goo deep in ocean, the diversity of life increases as seen in graph but then after a peak point declines rapidly. This is because at normal depth life thrive in normal conditions of temperature and pressure but deep down low, the pressure of water is so intense that it can even crush lead. So, the little amount of organisms that are living in those depths are highly evolved to that intense environment...
(c) Pollution puts a opposite effect on diversity either it is air, water or ground type of pollution. Marine biodiversity take a great loss from chemicals waste as well as the ground animals in which the viable environment gets completely destroyed. This is the main cause of extinction of various animal and plants species.
The correct answer is: 2.5%
The vast majority of the human genome (97.5%) is comprised of non-coding DNA with different functions. Non-coding DNA includes telomeres, introns, non-coding RNA genes and gene regulatory sequences.
• Telomeres-ends of DNA with protective role (prevents shortening of DNA),
• Non-coding RNA genes-e.g. genes for tRNA,
• Gene regulatory sequences such as promoter, enhancers and silencers.
I believe it would be 46 chromosomes.

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.
