<span>A: food chain

</span><span>In many functions of a living organism, it cannot make its own energy. It uses energy from its environment, retrieves and converts into a usable and edible matter. Organisms that can do this process is the autotrophs, they can facilitate photosynthesis which they gather energy from the sun, water and carbon dioxide in order to create energy by then, the transfer of this energy to other organism is played by the food chain –food web. </span>

anzhelika [568]

Given what we know, we can confirm that the process of differentiation alters the cells by changing the expression of genes in a cell.

<h3>What is differentiation?</h3>
  • differentiation is when a cell becomes specialized.
  • This is the case with heart or digestive cells.
  • Since all cells carry the same DNA, this does not account for differentiation.
  • Instead, this is achieved by changing the expression of genes in a cell.

Therefore, we can confirm that differentiation is what we refer to as a cell becoming specialized in one way or function, such is the case with heart cells or digestive cells, and since all cells in the body carry the same DNA, this is done by changing the way in which the cells express their genes in the DNA.

Suppose that part of an amino acid sequence of a protein changed from tyrosine-proline-glycine-alanine to tyrosine-histidine-gly
stira [4]

Suppose that part of an amino acid sequence of a protein changed from tyrosine-proline-glycine-alanine to tyrosine-histidine-glycine-alanine. This change was most likely caused by a point mutation called a <u>substitution</u>.

<u>Explanation:</u>

Any protein is synthesized by joining a number of amino acids together. This amino acid is placed based on the sequences of the DNA , for every 3 sequence there is an amino acid that is synthesized and therefore it is called as a triplet codon, since there may be many sequence for a single amino acid we call it as degenerate codon.
