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

What important event in translation happens after the incoming trna is in place?
denis-greek [22]

Answer:

Molecules  carrying amino acids are positioned in the  ribosome’s two docking sites.

Explanation:

A ribosome is a molecular machine that  coordinates protein assembly.

  • A ribosome brings together correctly the  mRNA, which needs to be translated, and  the tRNA, which assists in the translation process, to come together correctly.
  • During translation, tRNA molecules  carrying amino acids are positioned in the  ribosome’s two docking sites.
  • After the translation, the tRNA disassemble and is being reused many times.

List three reasons why plants and animals are valuable to the local economy. How could the endangered species act help or hurt a
katrin [286]

Answer:

Plants are valuable since they provide our food, materials for shelter, and purify the air (photosynthesis).

Animals such like livestock, supply us with food, fiber and leather.

The Endangered species act can help a local economy because it helps to supply clean air and pure water. It also protects our natural supplies.
