Why is meiosis important for organisms? It allows for genetic variation among organisms. It determines which genes are dominant
Studentka2010 [4]

Meiosis is important for organisms since it allows for genetic variation among organisms.

<h2>Further Explanation</h2><h3>Cell division</h3>
  • Cell division is the process in which cells undergo division to form other new cells.
  • There are two types of cell division;
<h3>Mitosis Division  </h3>
  • Mitosis is a type of division in which a parent cell undergoes division to yield two daughter cells that are similar to the parent cells.
  • The daughter cells have equal number of chromosomes as the parent and are identical to the parent.
  • This type of cell division normally occurs in somatic cells of organisms and facilitates growth and development of organisms.
<h3>Meiosis division</h3>
  • Meiosis division is a type of division that occurs in gamete cells where a parent cell divides into four daughter cells that differ from the parent cells in terms of the number of chromosomes.
  • In meiosis the daughter cells have half the number of chromosomes as the parent cells.
  • Meiosis occurs in the gamete cells and facilitates sexual reproduction in living organisms.
  • Meiosis occurs in two phases, that is, meiosis I and meiosis II
  • During the process of meiosis several processes occurs that cause genetic variation among organisms.
  • These processes include, crossing over, independent assortment of genes, among others.
<h3>Crossing over  </h3>
  • Cross over is the process that occurs during the prophase I phase of the first stage of meiosis known as meiosis I.  
  • During the process of crossing over, genetic material is exchanged between homologous chromosomes which enhances the genetic variation in organisms.

Keywords: Cell division, meiosis, crossing over, genetic variation

The development of nuclear power has provided electricity for less money, but at a cost. What may be considered a "cost" of nucl
ivolga24 [154]

The answer is; D

Radioactive waste poses a serious challenge to the environment. Any leakage of the waste is risky because the radioactivity can flow up the food chain and it also takes time for it to decay and become less harmful. Therefore, its effect can be felt over many generations. Therefore, safe storage of radioactive waste is a challenge (and can be very expensive) and a deterrent for pursuing the potent energy source.

Based on the function of dna polymerase explain why each part of the name dna polymerase makes sense?
Sauron [17]

The enzyme known as DNA polymerase is responsible for creating DNA from nucleotide monomers. The enzyme's functions are indicated by its name, DNA polymerase. The term "DNA" refers to the fact that it generates DNA utilising nucleotides. "Polymer" signifies that the enzyme is converting monomeric nucleotides into a polymer molecule. Lastly, "ase" refers to an enzyme.

<h3>What role does DNA polymerase play ?</h3>

The primary role of DNA polymerases is to preserve the genome and guarantee that the genetic code is reliably transmitted from one generation to the next.

  • The essential enzyme for replication in eukaryotes is DNA polymerase. Additional DNA polymerases are used for primer removal, repair, and proofreading.
