(a) The other function of the kidneys is to regulate the amount of sodium and potassium in the body.
The two bean-shaped organs, are equal to the size of our fist and are located just below the rib cage, one on each size.
The main function of the kidneys is to filter blood by removing extra water from the blood. Apart from this kidneys also regulate the amount of salt and minerals such as - sodium, potassium, calcium, and phosphorus in the blood because without the balance and regulation of the minerals the nerves, cells, and tissues of our body may not work normally. The kidney also produces hormones that help:-
- Control blood pressure
- Make red blood cells

Answer:
1:0
Explanation:
A dominant trait can be described as a trait which masks the effect of a recessive trait. A recessive trait can be described as a trait which gets suppressed by a dominant trait.
In the above-mentioned scenario as the dog carrying the dominant traits has homozygous alleles for both the traits, this means that the offsprings produced will have the same phenotype as the parent with the dominant alleles.
The genes received by the recessive parent will be suppressed.
Answer:
Let us consider the genes for black individual to be BB.
Let us consider the genes for bluish gray individuals to be BW.
The cross will be:
B W
B BB BW
B BB BW
The results show that there is a 50% probability that the offsprings produced will have black colour. There is also a 50% chance that the offsprings produced will have bluish graycolour.
<em>The genotypic ratio for black individual : bluish gray individual will be 2:2.</em>
<em>The phenotypic ratio for black individual : bluish gray individual will be 2:2</em>.
