Answer:
1. The parents genotypes could have been BO and AO
2. wire-hair
Explanation:
There are four possible blood types which are type A, B, AB, O. blood group is the classification of blood based on the presence or the absence of inherited antigenic substances on the surface of the red blood cells. They have hereditary basis and also rely on a series of alternative genes sometimes used in solving dispute of parental heritage. With the four possible blood groups, there are six possible genotypes and these are:
Blood type possible genotypes
Type A AA, AO
Type B BB, BO
Type AB AB
Type O OO
Thus, for parents with blood type B and A to give birth to a child with blood type O, it means their genotype could have been both BO and AO for them to be able to produce a child with OO. a cross between these two could give rise to OO.
Question 2
Wire hair is dominant (S) to smooth (s), thus wire hair could be in the homozygous (SS) and heterozygous form (Ss) and the smooth hair can only be expressed in the homozygous recessive form (ss).
thus, in a cross between homozygous wire haired and smooth haired, we will have:
homozygous wire haired homozygous smooth haired
P gen SS x ss
F1 gen. Ss
phenotype: wire haired

<h3><u>Answer;</u></h3>
The adrenal glands sit on top of the kidneys and release adrenaline, which affects heart rate.
<h3><u>Explanation;</u></h3>
- Adrenal glands are located at the top of each kidney. They produce hormones that help the body control blood sugar, burn protein and fat, react to stressors like a major illness or injury, and regulate blood pressure.
- The Adrenal glands are made up of two regions; the adrenal cortex and the adrenal medulla. <em><u>The adrenal medulla produces hormones adrenaline also epinephrine and noradrenaline also norepinephrine. </u></em>
- <em><u>Hormone adrenaline rapidly responds to stress by increasing your heart rate and rushing blood to the muscles and brain.</u></em>
