Answer:
d. to protect the end of a DNA molecule
Explanation:
Telomeres are like the protective shields of our cells' DNA.
Its name, of Greek origin, literally means "final part", and the telomeres are that: the ends of the chromosomes, something similar to the plastic tips of the shoelaces.
But they are very repetitive and non-coding parts of DNA: their main function is to protect the genetic material that carries the rest of the chromosome.
As our cells divide to multiply and to regenerate the tissues and organs of our body the telomere length is reduced, and so over time they become shorter.
When the telomeres finally remain so small that they can no longer protect the DNA, the cells stop reproducing: they reach a state of old age or old age.
Therefore, telomere length is considered a key "biomarker of aging" at the molecular level, although it is not the only one, and in recent years it has attracted the attention of numerous investigations.
The correct answer is option D. produces an adult that's completely different from the larva.
In the incomplete metamorphosis there are three stages, egg, nymph and larva. The nymph hatch from egg, and look similar to the adult.
Unlike this, in complete metamorphosis, there are 4 stages, egg, larva, pupa and adult. In this case, the larva is completely different from the adult. For example, the butterfly larva, which is a caterpillar is completely different from adult butter fly.
Answer:
No, it wouldn't provide all the elements needed to assemble lipids, nucleic acids or proteins.
Explanation:
As it can be seen from the diagram, the breakdown of glucose molecules will release hydrogen, carbon and oxygen. All these elements are needed to make lipids, proteins and nucleic acids. But apart from these elements, other elements are also required for the making of these compounds. For example, nucleic acid would require the elements nitrogen and phosphorus apart from carbon, hydrogen and oxygen for its making. Proteins would need nitrogen, sulphur and selenium apart from carbon, hydrogen and oxygen.
I hope this works
