Answer:

AB

Explanation:

Blood group is discovered by famous scientist Karl Landsteiner in the year 1990. Co-dominance is the expression of the two alleles in the heterozygotes. In AB type, the two different alleles are present and they are expressed.

However in ABO type, it is govern by three allele namely A, B and O type. If only the antigen A is present, it is called A blood type. When only B antigen is present it is called B blood type and when both A and B are present, it is called AB blood type. And if neither of the antigen are present, it is called the O blood type.

The allele O is of recessive to both the blood type A and B. So a person with O blood type have two copies of O allele. But however A and B blood type are dominant of O, a person with A blood type may have one of the two genotypes --  AO or AA. Similarly, with blood type B, the genotypes are BO or BB.

Select all that apply: Which of the following affect(s) the half-life of a radioactive substance?
frutty [35]

Answer:

The correct answer is option A, the type of isotope

Explanation:

The half life of a radioactive substance is a constant value and thus it is not affected by the temperature, catalyst or mass of the substance.  Basically it is the time taken by a radioactive substance to reduce its mass by half of its actual value. Radioactive decay takes place only when the atomic nucleus becomes unstable and thus the isotope type is the only factor which affects the radioactive decay of any element.
