<h2>Answer 1 with Explanation</h2>
Homozygous dominant- It can be an organism if it carries two copies of the same dominant allele as homozygous which clearly means that the organism has a pair of models that is the corresponding allele for a gene. This gene originally belongs to a particular gene that has same alleles on both homologous chromosomes. It is assigned to by capital (XX) in the subjective terminology.
<h2>Answer 2 with Explanation</h2>
Heterozygous dominant is an organism that carries two different alleles of a gene. Though this is originally is referred to as (Tt). Heterozygous means that an organism has two different varieties of the gene within the system of dominant, the protein each makes is slightly different from one another and the organism has both tall and short versions within the dominant.
<h2>Answer 3 with Explanation</h2>
Homozygous recessive is described as an organism that carries two copies of the same recessive allele in the living organisms while they are in process of growth. A recessive gene is one that has to be homozygous to have an effect on the plant's or animal's traits that is naturally in process. This process of homozygous is is referred to by the lower case (xx).
A heterozygous cat has a genotype Hh
A hairless cat has a genotype hh
When crossed, the results could be any of the following:
Hh (with hair)
hh (hairless)
There is a 50:50 chance or 1: 1 ratio that the offspring will have hair.
It would be support and movement of the skeleton
Blood Volume is determined by the ratio or red blood cells to the whole blood volume.
Answer:
B
Explanation:
For the body to maintain stable conditions for optimal working of biochemical activities in cells, then it will require to constantly readjust any imbalances and offshoots that occur (which is the case regularly) through a positive and negative feedback mechanism. An example is blood sugar. After food intake, the blood sugars tend to rise a bit and the body produces more insulin to communicate to the cells to take up the excess glucose from the blood and store it. During starvation when the blood sugar tends to drop below normal levels, the level of insulin is reduced and that of glucagon is heightened. This causes the stored glucose to be released into the blood to restore homeostatic levels. This kind of balancing act happens with many other variables in the body.
