People with HIV are unable to fight off these rare diseases because they have a weakened immune system.
<span>An organism of the Kingdom Protista could be organisms that are eukaryotic. Though they are such, some organisms that belong in this kingdom can't be classified as a plant, animal or fungus. Organisms like algae and kelp which belong in this kingdom are multicellular and they are able to provide for themselves food, shelter, and oxygen in underwater environments.</span>
Answer:
- The blood group of the father must be B.
- The genotype of blood group would be
. - The Rh factor of the father can either be positive or negative.
- Thus, the genotype of Rh factor of father would be either Rr or rr.
Rh factor:
The phenotype of the mother Rh factor is positive. Thus, she can have Rr or RR as her genotype as positive is a dominant trait.
If the genotype of the mother is RR then all the offspring would be positive for Rh factor. However, one of the offspring is Rh negative, that means the mother must be heterozygous that is, Rr.
The genotype of the father can either be Rr or rr in order to produce offspring with positive as well as negative Rh.
Blood group:
The blood group of the mother is A. Thus, the genotype can either be
or
.
However, the blood groups of the children are O+ and B+.
Thus, the genotype of the mother must be heterozygous that is
.
The blood group of the father must be B with genotype
in order to produce offspring with blood group O and B.
Answer:
decreased body temperature
Explanation:
Muscles also need oxygen to function properly. Given that blood flow must be maintained at high levels to supply oxygenation and muscle substrates, mechanisms have been found to facilitate this process. Among the processes that facilitate the transfer of oxygen to tissues, we can mention lowering blood pH, increasing carbon dioxide and increasing exercise.
Lower body temperature, in turn, makes it difficult to transfer oxygen to tissues, causing fatigue, pain and other problems.
