A scientist thought he may have discovered a new plant compound that would lower blood pressure in people. In his first experime

nt, he injected one hundred mice with the compound and found that the blood pressure in ninety-five of the treated mice was not affected. However, all of the mice seemed to grow at a faster rate then the control group. Which statement describes the most likely outcome of this investigation? The knowledge gained will lead to further experimentation that could potentially result in a new use for the drug. He will develop a second experiment to find a way to make the drug successfully lower blood pressure in mice. The data he collected will be used in new investigations to determine why certain people are taller than others. He will use these results to conclude that the drug will most likely lower blood pressure in five percent of people.

Eukaryotes include options (A) and (D), while bacteria only pertains to (E), and both (B) and (C). (A) Eukaryotes are the only ones that possess a nucleus. (B) Both types duplicate their DNA prior to cell division, ensuring each cell retains a copy. (C) The structural element is known as a centromere in eukaryotes, whereas bacteria use the origin of replication for this function. (D) Centromeres are unique to eukaryotes. (E) Bacteria exclusively contain a replication origin.

Utilize the Hardy Weinburg equation pertaining to allelic frequency.

P2+2pq+q2=1

Calculating gives us 174/1378 = 0.126 = q2

Consequently, q2 equals 0.126, which means q = 0.355.

<pGiven that q = 0.355 and noting that p + q = 1, therefore

P = 1 – 0.355 = 0.645.

To determine the population of homozygous dominant (p2);

(0.645)2 x 1378 = 0.416 x 1378 = 573.

For the heterozygous population (2pq);

(2 x 0.645 x 0.355) x 1378 = 0.458 x 1378 = 631.

The number of recessive individuals (q2) equals 174.
