C. 0%
Explanation:
Birth Rate is the fraction of the number of babies born every year per 1000 individuals in a population. Death Rate is the fraction of the number of deaths every year per 1000 individuals in a population.Given: The birth rate = 10 per 1,000
The death rate = 10 per 1,000
Since the birth rate and the death rate both are same then there is no change in the population.
Therefore , there must be zero percent population growth or decay.

a) The single base change mutation occurs at the beta chain of haemoglobin when glutamic acid is replaced with valine.
b) Sickle Cell Anemia is inherited in an autosomal recessive pattern.
Explanation:
Haemoglobin is a protein found in the red blood cells whose main function is to transport oxygen. Sickle Cell Anemia is a disorder caused by a base change in DNA beta chain of haemoglobin. The amino acid valine is substituted for glutamic acid at one point in each of the two beta chains. When this type of hemoglobin is exposed to low oxygen, it forms elongated crystals inside the red blood cells that are sometimes 15 micrometers in length. These make it almost impossible for the cell to pass through many small capillaries, and the spiked ends of the crystals are likely to rupture the cell membrane, leading to sickle cell anemia.
In describing the inheritance patterns of sickle cell anaemia, it is of autosomal recessive pattern. This means that the parent of the affected individual both carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. The gene for normal red blood cell is dominant over the gene for abnormal red blood cell which is said to be recessive. A person who is a stickler should have the genotype SS.
