Answer:
The fraction of heterozygous individuals in the population is 32/100 that equals 0.32 which is the genotipic proportion for these endividuals.
Explanation:
According to Hardy-Weinberg, the allelic frequencies in a locus are represented as p and q, referring to the alleles. The genotypic frequencies after one generation are p² (Homozygous for allele p), 2pq (Heterozygous), q² (Homozygous for the allele q). Populations in H-W equilibrium will get the same allelic frequencies generation after generation. The sum of these allelic frequencies equals 1, this is p + q = 1.
In the exposed example, the r-6 allelic frequency is 0,2. This means that if r-6=0.2, then the other allele frequency (R) is=0.8, and the sum of both the allelic frequencies equals one. This is:
p + q = 1
r-6 + R = 1
0.2 + 0.8 = 1
Then, the genotypic proportion for the homozygous individuals RR is 0.8 ² = 0.64
The genotypic proportion for the homozygous individuals r-6r-6 is 0.2² = 0.04
And the genotypic proportion for heterozygous individuals Rr-6 is 2xRxr-6 = 2 x 0.8 x 0.2 = 0.32
Answer: B is right
Explanation: Carbon dioxide is a greenhouse gas which is involved
with increasing temperature of atmosphere
75% purp, 25% white i would think. you could easily eliminate the 50% purp 50% white because that wouldn’t make sense, purp is the dominate color. it would most likely not be 100% purple because there are two 25-75 answers, which would most likely make it one of those answers. since purp is the dominate color, 75% white would not make sense, making the correct answer 75% purp and 25% white.

The correct answer is D. Separate injections of tetanus toxoid and tetanus antitoxin in different sites on this visit to ensure active and passive immunization.
Explanation:
Tetanus is a bacterial infection caused by Clostridium Tetany, this occurs as an object with the bacteria cuts the skin or causes a wound. Due to this, every time there are lacerations or cuts in an accident it is important to provide protection against Tetanus. This commonly occurs through the Tetanus vaccine also know as tetanus toxoid that is administered during childhood and works through passive immunization. However, if the patient has not been previously immunized he/she must receive tetanus toxoid and separately tetanus antitoxin that prevents tetanus through active immunization.
According to this, in the case presented the patient should have separate injections of tetanus toxoid and tetanus antitoxin (Option D) because this patient has not been previously immunized and therefore requires both tetanus toxoid and tetanus antitoxin, additionally, as each of these is different, they should be administered separately, but almost at the same time to prevent tetanus infection.
