Telomeres are protective sequences of nucleotides found at the ends of chromosomes,Which become shorter every time a cell divides.
A gradual degeneration of an organism occurs, resulting in ageing.
However, some cells are able to replenish their telomeres using the enzyme telomerase.
Hope this helps! :)

<span>Prokaryotic cells reproduce by</span> binary fission , which includes the chromosomes splitting into two equal parts.
Answer: A. In the electron transport chain, a series of reactions move electrons through carriers.
B. The products of the electron transport chain are H2O and either NAD or FAD.
E. The electron transport chain is a series of oxidation-reduction reactions that occur in the inner mitochondrial membrane.
Explanation:
the best suitable statement is it transfers energy stepwise from one compound to another, The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons are transferred from one member of the transport chain to another in a series of redox reactions.
Anabolic steroids are synthetic forms of the male hormone testosterone that are used to cause muscle hypertrophy.
It is properly knowns as anabolic-androgenic steroids (AAS). They are anabolic in nature and increases the protein found within the cells especially in the skeletal muscles. It also has varying degrees of androgenic and virilizing effect which includes inducing the development and maintenance of male secondary sexual characteristics such as facial and hair body growth.
In the 1930s AAS were synthesized and are recently used as a therapeutic medicine to stimulate muscle growth, increase appetite, induce puberty in males and treat wasting conditions among cancer and AIDS patients. It was also acknowledged by the American College of Sports Medicine that AAS, when joined with an adequate diet, can contribute to increasing the body weight, often as lean mass increases and the gains in muscular strength are achieved by doing high-intensity workout and proper diet.
