It is the telomeres that play<span> a major role in the aging process by serving as biological clocks that control the number of times cell division can occur. 

A telomere is a district of tedious nucleotide groupings at each end of a chromosome, which shields the finish of the chromosome from disintegration or from combination with neighboring chromosomes. 
Be that as it may, there are as yet genuine questions about whether turning around or backing off maturing by means of telomerase action is the appropriate response. Since while telomerase lengthens telomeres, in people with disease, the protein enables existing tumors to become speedier.</span>

Which of the following is true?
hodyreva [135]

C

Remember that weight is calculated as mass * gravity

Explanation:

Weight is the result of the influence of gravity on the mass of an object. Therefore, differences in gravity will cause an object of the same mass to weight differently on a scale. On the moon, an astronaut would weight 1/3 of their weight on earth. This is because the gravity on the moon is approximately 1/3 that on earth. The influence of gravity is also higher the larger the mass of an object.

What is the limiting factor when performing high intensity anerobic activities?
dexar [7]

Glucose is the limiting factor when performing high intensity anaerobic activities.

Exercise can cause profound changes on glucose homeostasis in the body. For those people who have type 1 diabetes, aerobic exercise usually causes blood glucose concentration to rapidly drop. On the other hand, anaerobic exercise may cause it to rise, thereby making glycemic control difficult and challenging. Continuous glucose monitoring can increase self-efficacy for those individuals who are prone to hypoglycemia and hyperglycemia.
