With which pair would you see the biggest differences in the microbiota: your cheek
Nimfa-mama [501]

The biggest difference in the microbiota can be seen in : ( B ) your cheek versus your friend’s cheek.

<h3>What is Microbiota </h3>

Microbiota is the microorganisms present in specific region or area and It protects the region from harmful indigenous microorganisms as well. The microbiota specie that is present in an individual varies greatly from the microbiota species present in a different individual.

Therefore the Microbiota species present in your cheek will vary greatly from the microbiota species present in your friend's cheek.

Hence we can conclude that The biggest difference in the microbiota can be seen in  your cheek versus your friend’s cheek.

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

kompoz [17]

Answer:

The probability of the study result being subject to bias while interpreting -------- it's a YES

Explanation:

Probability of Leukemia

A. Among traced group

= 4/1,870 persons.

B. Among self-reported group

= 4/443 person.

We can deduce

A higher rate of occurrence in self-reported group which could be causesd by fear of leukemia occurrence or suspicion of their previous exposure at atomic sites
