Explanation:
Echinoderms get their food and oxygen for energy. They use tube feet to obtain from the water. The tiny tube feet are involved in passing collected food towards the central mouth.These animals are detritivores performing similar functions to earthworms on the land in recycling nutrients.
Through <u>immense amounts of heat that come from the phase of mountain building</u>, it will cause the amount of heat and pressure that will cause the rocks to go through the <u>rock cycle</u> of bending, folding, crushing, flattening, and shearing to become a metamorphic rock. Metamorphic rocks through all the compact pressure and heat will <u>become way harder </u>than that of a sedimentary rock which will indicate that of a metamorphic rock.

I am not really sure but you can get the answer from it :
They discovered a fundamental mechanism of how proteins protect chromosomes while DNA is being copied (a process called DNA replication), which relies on a protein called RPA. Cells have a limited amount of this protein, which they use as 'band aids' to protect the DNA temporarily during replication.
