Answer: the bloodtype of Jesse is A Rhesus D positive
Explanation:
Antigens at present on the blood cells while antibodies are present in the serum. Thus, to prevent agglutination which occurs if the red blood cell antigen is similar to the antibody, the red blood cell of Jesse which has the B antigen will have the A antibodies produced. Thus, since the red blood cell determines the bloodtype of a person, Jesse therefore has the B bloodtype.
Answer:
Molecules.
Explanation:
Molecules are the items that attach on the inside of the mineral to give the mineral its shape. The molecule of a mineral is a crystal three-dimensional regular structure (arrangement) of chemical particles that are bonded together and determines its shape.
Due to the fact that, these molecules are structurally arranged or ordered and are repeated by different symmetrical and translational operations they determine the shape of minerals.
The theory of continental drift was given a scientific status during the:
1960's.
Answer:
d. 1/3
Explanation:
Given, M is a dominant allele which is responsible for tailless kittens and m is recessive wild type allele which leads to kittens with tail. M is a lethal allele which means that if it is present in homozygous condition, the kitten will not survive. So the Manx cats should be heterozygous i.e. Mm.
When they mate, Mm X Mm :
M m
M MM Mm
m Mm mm
1/4 kittens will have MM genotype so they will not survive. Out of the remaining kittens, 1/3 will be mm and hence they will have normal tail. Remaining 2/3 will have Mm genotype like their parents and will be born without tail. Hence, there is 1/3 probability that one of the four kittens will have a normal tail.
