A.  Fine Focus.

B.  Nucleus, Cytoplasm, and membrane

C. 30 Micrometer.

Erythrocytes are well known to have no nucleus but in fact, they lack most organelles such as the Golgi apparatus endoplasmic reticulum and mitochondria. Hair consists of two parts the root and the hair shaft. The root is the part of the living hair located in the middle layer of the skin the dermis.

Epidermal root cells in some plants produce root hairs and tubular growths that increase the surface area of ​​the root. Unlike other cells in the body, red blood cells do not have a nucleus. This habit dates back to when mammals began to evolve. Other vertebrates such as fish reptiles, and birds have erythrocytes that contain dormant nuclei. To allow red blood cells to carry an increased load of oxygen cells evolved to function without a nucleus and other associated organelles.

Sickle cell anemia is a autsmal recessive blood disorder of RBCs where RBC shape altered to the sickle shape or cresecent moon that obstruct and damage the veins and artries.

Normal allele is represented by - HbA - p

sickel cell allele is represented by - HbS - q

genotype frequency of normal allele HbA in the population = p2

genptype frequency of HbAHbS in the population = 2pq

genotype frequency of autosomal recessive HbS = q2 = 0.007 (given)

So, the allelic frequency of the recessive allele =

q =  √ 0.007 = 0.08366 or 0.084
