Answer:
amino acids
Explanation:
Proteins are made up of small units called amino acids. The proteins are composed of carbon, hydrogen, oxygen and nitrogen. In addition to nitrogen, proteins may contain phosphorus or sulphur or both. The proteins are referred to as nitrogenous compounds because they contain nitrogen element.
Because identical twins begin as a single fertilized egg that then separates, identical twins share 100 percent of genetic makeup.
<h3>IDENTICAL TWINS:</h3>
Identical twins are a type of twins characterized by their phenotypic similarity. They look so much alike that they are almost morphologically indistinguishable.
Their similarity emanates from their genetic content. Identical twins are formed when two sperms fertilize a single egg, which then splits into two.
Since identical twins begin as a single fertilized egg that then separates, this means that they share 100% of their genetic makeup.

Answer:
The right answer to this question is option D. Convergent evolution.
Explanation:
Convergent evolution is a process defined by when an organism develops the same, or at least near that, characteristics, for a specific reason, but they don't have the same origin. In this case, the cacti in both deserts have pretty much the same characteristics, and this happens because both these plants need water to survive, and in order to save it, they have barrel-shaped stems, short-lived leaves, and spines. All of these things help them in saving the water and capturing it when it's possible.
The convergent evolution is when both these organisms develop equally, but are not originally from the same place, the environment being the one to shape this.
Answer:
At the “center” of each amino acid is a carbon called the α carbon and attached to it are four groups - a hydrogen, an α- carboxyl group, an α-amine group, and an R-group, sometimes referred to as a side chain.
