Question

what is the total number of chromosome pairs in a typical human cell?
a. 48
b. 23
c. 24
d. 46
why is understanding genetic diversity crucial in medical research?
a. creates limitations in treatments
b. doesnt impact medical research
c. hinders scientific progress
d. helps understand how diseases manifest differently and develop tailored treatments
what is the significance of embracing genetic diversity?
a. excludes individual differences
b. promotes uniformity
c. fosters discrimination
d. celebrates differences among individuals

Explanation:

First Question:

A typical human cell (somatic cell) has 23 pairs of chromosomes, totaling 46 chromosomes. So the number of chromosome pairs is 23.

Genetic diversity means different individuals have different genetic makeups. In medical research, this helps in understanding how diseases show up differently in people (due to genetic differences) and allows developing treatments that are tailored to specific genetic profiles. Options a, b, c are incorrect as they state negative or untrue impacts, while d correctly states the positive role of genetic diversity in medical research.

Embracing genetic diversity means recognizing and valuing the differences in individuals' genetics. Option a is wrong as it says excluding differences, b is wrong as it promotes uniformity (opposite of diversity), c is wrong as it fosters discrimination (not related to embracing diversity). Option d says it celebrates differences among individuals, which is the correct significance of embracing genetic diversity.

Answer:

b. 23
