Answer:
25%
Explanation:
Let's assume that the recessive allele "p" imparts diseased conditions in the homozygous genotypes. The genotype of each of the carrier parents would be "Pp". A cross between Pp and Pp would produce progeny in the following phenotype ratio=
Pp x Pp= 3/4 Normal : 1/4 Affected.
Therefore, there are 1/4 or 25% chances for this couple to have a child with PKU.
The shape of the earth affects our view of the stars because since we are shaped a sphere, we get more of a view of many different stars and not much is blocking our view
The science of Cancer Biology focuses on the study of the different mechanisms and fundamental process of cell growth, the transformation of normal to cancer cells, and the metastasis or spread of these cancer cells to other parts of the body.
As such, it includes the study of how tumor cells develop and grow. It also includes studying how the immune system responds to cancer cells, thus including macrophages and their response to the presence of pathogens and cancer cells. Underlying all these is the inclusion of a study on protein synthesis as it is the process where biological cells build and create new specific proteins in the body.
<span>Positive Rh factor represents the presence of the rhesus protein on the blood cells.</span> <span>Rh factor or Rhesus factor is used to describe the presence of antigen Rh (D) in the blood. A person who is, for example, AB Positive (AB+) has the A and B antigens and the Rh(D) antigen, whereas someone who is AB Negative (ab-) lacks the Rh(D) antigen. Antibodies to Rh antigens can be involved in hemolytic transfusion reactions and they increase the risk of Hemolytic disease of the fetus and newborn, so it is important for mother and the baby to have the same Rh factor.</span>
Answer:
Molarity is the most useful concentration for chemical reaction in solution ... As an example, suppose we dissolve 23 g of ammonium chloride (NH4Cl) in enough water ... Now, suppose we have a beaker with 175 mL of a 0.55 M HCl solution.Explanation:
