Answer:
There is no punnet square attached but generally none of the offsprings from this cross will be homozygous dominant. The answer is 0.
Explanation:
The question illustrates a single trait encoded by a single gene. According to Mendel, a gene comes in two alternative forms called ALLELES. Each allele encodes different characters of the same gene. For example, let's use the trait for height encoded by a certain gene that has alleles T for tallness and t for shortness. T is dominant over t, meaning that T (tallness) will always mask the phenotypic expression of t (shortness) in a heterozygous state.
A heterozygous parent contains different alleles of the same gene i.e. Tt in this case. However, due to the dominance of allele T (tallness) over allele t (shortness), the tall trait will be expressed. On the other hand, a homozygous recessive parent contains the same alleles for the recessive trait i.e. tt
Using a punnet square, a cross between a heterozygous (Tt) parent and a homozygous recessive parent (tt) will produce offsprings with genotypes: Tt and tt in a 1:1 proportion.
Tt is heterozygous dominant
tt is homozygous recessive
None of the offsprings are homozygous dominant (TT), hence, the probability of producing a homozygous dominant offspring is 0.
t t
T Tt Tt
t tt tt

The one u put should be correct
Answer:
A) You need to report the needle stick to your supervisor as soon as possible.
Explanation:
To begin, every accident in a hospital has to be immediatly reported to the supervisor in charge. Even if it wasn´t harmful, there are several forms that have to be filled in order to avoid further accidents.
Also, the supervisor has to follow the procedures needed. In this case, even though you have all the vaccines, in order to prevent any symptom, you have to be in medication immediatly, not in two weeks but right away.
The other set of vaccines is not needed because you were already in contact with the infection and your inmunity system already made defenses for further exposures.
