Answer:
Punnett square is a square diagram which is used to predict the genotype of the offspring produced by particular cross.
Let P and p be the alleles of the gene responsible for the flower colors in a plant.
The genotype of both the parents is given as heterozygous that is, Pp.
Two types of gametes would be formed P and p.
The cross is shown in the image below.
The cross would be result in offspring with three types of genotypes PP, Pp and pp in 1:2:1.
In DNA, the "rungs" between the two strands of DNA are formed from the nitrogenous bases adenine, thymine, guanine and cytosine
I believe the answer is D. don't take my word for it though I may be wrong
Pharmaceutical sales representatives must have a very solid understanding of not only how the human body works because while they are not doctors that prescribe the medications, they do need to convince physicians that their medications are the best option for treatment of disease. Doctors will have questions regarding composition, effectiveness, the medications pathway, side effects, etc. and a representative can only answer these if they understand how the body works. They must be able to explain how and why the medication they are presenting offers the best option in pharmaceutical care.
