Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

<h2>Homologous genes get Highly Conserved</h2>

Explanation:

  • Eukaryotes are those organisms whose cells possess a nucleus which is enclosed within membranes.
  • Plants such as Apple trees
  • Animals such as Dogs and cats
  • Fungi such as Mushrooms
  • Protists such as Paramaecium
  • Amoeba are the examples of Eukaryotes.
  • Eukaryotic cell possess several rod shaped chromosomes.
  • Eukaryotic cells contain membrane bound organelles such as Golgi apparatus and Mitochondria, Chloroplast.
  • Asexual and Sexual types of reproduction is seen in Eukaryotes.

In which of the following structures of a vascular plant would you expect to find totipotent cells? select all correct choices.
natita [175]
The choices can be found elsewhere and as follows:

A. mature leaves
B. shoot apical meristem
C. cell elongation zone
<span>D. axillary buds
</span>
I think the correct answers are option B and D. It would be at the shoot apical meristem and the axillary buds that <span> a vascular plant would you expect to find totipotent cells. Hope this answers the question.</span>

alukav5142 [94]
Pectinate muscles are parallel ridges in the walls of the atria of the heart. The name is due to their resemblance to the teeth of a comb (pecten). The heart is the organ  pumps blood to all parts of the body. It is made up of four chambers, that is, right and left ventricles, left and right atria, and the blood vessels, Pulmonary artery, pulmonary vein, aorta, and venacava. An auricles are pouch like structure that increase the total filling capacity of the atrium and also increase the volume of blood that an atrium is able to contain.

AfilCa [17]

Polymers are made of individual subunit called monomer.

<u>Explanation:</u>

Polymers are lengthy chains built up of replicating molecular subunits, named monomers. The term polymer becomes from poly- (many) and -mer (part). A polymer may be a real or manufactured macromolecule composed of recurring units of a smaller molecule (monomers). The term monomer comes from mono- (one) and -mer (part).

Monomers make polymers by creating chemical bonds or confining supramolecular by a method called polymerization. Examples of polymers comprise plastics like polyethylene, silicones. Polymerization is the method of covalently bonding the smaller monomers into the polymer. While polymerization, chemical groups are failed from the monomers so that they may join together.
