During meiosis I, ____________ chromosomes line up side by side and may shuffle genetic material between themselves.
lozanna [386]

During meiosis I, homologous chromosomes line up side by side and may shuffle genetic material between themselves.

<h3>What is Meiosis?</h3>
  • In sexually reproducing organisms, meiosis is a unique type of cell division of germ cells that results in the production of gametes, such as sperm or egg cells.
  • Two rounds of division are necessary, and the end product is four cells with just one copy of each chromosome.
  • Prophase I, Metaphase I, Anaphase I, and Telophase I are the four phases that make up Meiosis I.
  • It deactivates the sporophytic information while activating the genetic information for the production of sex cells.
  • By halving the same, it keeps the chromosomal count constant.
<h3>What is chromosome?</h3>
  • A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code.
  • Histones, which serve as packing proteins for the majority of eukaryotic chromosomes, work with chaperone proteins to attach to and condense the DNA molecule in order to preserve the integrity of the molecule.

The shape of each of the molecules is important because A) if the shape of any molecule in an organism changes, the DNA in that
dexar [7]

Answer:

The correct answer would be - C) the shape of a molecule determines how it functions in chemical reactions

Explanation:

The molecular shape of the molecules is one of the important characters of the molecules. It is important due to the fact that molecular shape determines how a molecule will react and interact with other molecules.

The shape of the molecules determines boiling point, melting point as well as various chemical reaction by determining the bonds. For instance, H2O or water has a tetrahedral shape which affects its bonding and properties. If molecules were linear in  shape there would be no life existed.

Thus, the correct answer would be - C)

You are conducting a case control study to determine if an association exists between melanoma and indoor tanning. From a statew
Aleksandr-060686 [28]

Answer:

a. Odds ratio = 1.58

b.  Inasmuch the odds ratio is greater than 1, this means that higher odds of melanoma exist in people exposed to indoor tanning, than in those not exposed to indoor tanning

Explanation:

For case  study                                                  

Let 'a'  represent the total population of people with melanomia = 696                                                      

Let 'b' represent the total number of people with melanomia exposed to indoor tanning  =  1107 – 696 = 411 people

For  control study

Let 'c' represent the total population = 1500

Let 'd' represent the total number of people not exposed to indoor tanning = 1500 - (0.428 * 1500)

                                                          =  1500 - 723

Total number of people not exposed to indoor tanning   = 777 people

                                                       

a. Odds ratio = (a/b) / (d/c) = (696/411) / (777/723)

                                                = 1.69 / 1.07 = 1.58

b. Inasmuch the odds ratio is greater than 1, this means that higher odds of melanoma exist in people exposed to indoor tanning, than in those not exposed to indoor tanning.
