Answer:
C) B, secretor
D) B, Nonsecretor
E) A, secretor
F) A, nonsecretor
Explanation:
When you cross AB(codominant) with O(homozygote recessive), it will result in 50% A(IaIo) and 50% B(IaIo).
The secretor gene is dominant and both parents are a heterozygote, so the ratio of offspring genotype should be 1 : 2: 1 while the ratio of the phenotype will be 3 secretors: 1 nonsecretor.
The possible phenotype will be:
B nonsecretor
A secretor
A nonsecretor
B secretor
B nonsecretor
Answer:
The hemolytic anemia is a disorder in which the destruction of the RBCs is faster than their production of the RBCs. Hemolysis is the term used for the destruction of the RBCs.
The body of an individual produces antibodies if it senses or there is an antigen that is foreign to the body that helps in the destruction or removal of the particular antigen with the help of antibodies or B cells.
Rh(D) antigen is foreign to the Rh-negative woman as her RBCs surface lack the D antigen so if RBCs expressed to mother blood, IgG production begins and travels to the fetus through the placenta and start destroying RBCs of the fetus. Hemolysis of fetus results in hemolytic anemia and some times death of the baby.
DNA is located in the nucleus of the cell, and makes up the chromosome found there. DNA is often called the building blocks of an organism?????
The answer is B, it is the only answer that talks about electric signals.
Answer:
Explanation:
The vertebrate land invasion refers to the aquatic-to-terrestrial transition of vertebrate organisms in the Late Devonian epoch. This transition allowed animals to escape competitive pressure from the water and explore niche opportunities on land. Fossils from this period have allowed scientists to identify some of the species
