The type of shock presented by a patient with a known history of gastric ulcers and gastrointestinal bleeding with recent history of passing a lot of blood is called hypovolemic shock. The patient is now on the later stages of shock as he is tachycardic and hypotensive (significant as mechanisms to maintain a normal blood pressure is failing at this point).
Comets originate from the Kuiper belt while asteroids originate from the Oort cloud. The Kuiper belt is within the solar system while the Oort cloud is outside the solar system.
For every trait, there are two types of characters - dominant and recessive which are determined by the combination of the alleles for a given gene.
Each gene has 2 types of alleles- one is the dominant allele which always expresses itself that is in both homozygous and heterozygous conditions whereas the other one is the recessive allele which can only express itself in the homozygous conditions.
In Mendel's experiments when he crossed plants with different traits he observed that in the F1 generation there was always a single trait that was getting expressed and it was the trait that was being coded by the dominant allele.
