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.

In the polymerization of DNA, a phosphodiester bond is formed between a phosphate group of the nucleotide being added and which
valina [46]

Answer: B

Explanation:

During polymerization of nucleotides to form nucleic acids, the hydroxyl group on the phosphate group attaches to the 3’ carbon of a sugar of one nucleotide to form an ester bond to the phosphate of another nucleotide. The reaction forms a phosphodiester linkage and eliminates a water molecule.

The DNA strands generally runs from 5 prime to 3 prime direction.

What is a difference between starch and glycogen?
deff fn [24]

The right answer is B.

Starch is, along with cellulose, the most common polysaccharide in the plant world. It constitutes the essential energy reserves of plants and is a component of the diet of humans. It is part of the group of slow sugars. Its consumption is particularly recommended to those who practice a sport.

There are no known motor proteins that move on intermediate filaments (IFs).
Harlamova29_29 [7]

Answer: The correct option is E ( Intermediate filaments are unpolarized).

Explanation:

Intermediate Filaments are usually associated with cells that can withstand mechanical stress which includes claws of animals, hair and makes up the dead remnants of the epidermal cell of the skin. Therefore without the supporting network of intermediate filaments, an epithelium remains intact but the cells are prone to damage by abrasive forces.

Intermediate filaments are so named because they are thicker than actin filaments and thinner than microtubules or muscle myosin filaments

The properties or characteristics of an intermediate filaments that explains the lack of motor proteins is as a result of its subunits which are elongated, not globular and are associated in an anti-polar manner. Therefore, the overall filament has no polarity, and therefore no motor proteins move along intermediate filaments
