Answer:
Phenotypes of offsprings: Type A, Type B
Explanation:
This question involves a single gene for blood group in humans. The ABO blood group system consist of three alleles: A, B, and O. A and B are dominant over O but co-dominant to one another.
If a woman with type O blood (OO) has a child with a male with type AB blood (AB) i.e OO × AB, the following gametes will be produced by each parent:
OO - O
AB - A and B
Using these gametes in a punnet square (see attached image), the offsprings with the following genotyoes will be produced: AO (2), BO (2)
AO - phenotypically type A
BO - phenotypically type B
Hence, a type A and type B blood group offsprings will be produced.
living things need non living things to survive. Without food, water, and air, living things die. ... Plants use water from the soil, carbon dioxide from the air, and energy from sunlight to make their own food.

A) %A=5 %G= 45 %C=45 %T=5 %U= 0
.
Explanation:
DNA is the genetic material and transfer from one generation to the generation. The DNA composed of the nitrogenous bases, pentose sugar and the phosphate group.
The base pairing of DNA follows the Chargaff's rule. According to this, the purines an pyrimidine ratio is equal to 1. The number of adenine is equal with that of thymine and number of cytosine is equal to the guanosine. In option (A) this criteria is follows.
Thus, the correct answer is option (A).
