Heterozygotes at the sickle-cell locus produce both normal and abnormal (sickle-cell) hemoglobin (see Concept 11.4). When hemogl
Stels [109]

Answer:

In an individual's molecular and cellular level, the heterozygote alleles are preferred over the homozygote alleles. In humans, the heterozygote alleles are found at a locus of beta polypeptide subunit of hemoglobin, while on the other hand, the homozygous alleles found at a similar locus are prone to sickle cell disease.  

The individuals carrying homozygous alleles exhibit sickle-shaped RBCs and they also possess low oxygen-carrying capacity, which ultimately results in brain, kidney, or heart failure. However, in the case of heterozygous alleles, the configurations of RBCs are of two kinds, that is, normal shaped and sickle-shaped. Thus, there are not enough sickle-shaped cells to result in the condition.  

The heterozygote alleles are resistant to malaria, thus, in tropical areas, where malaria is a prime issue the heterozygote alleles are preferred over the homozygote dominant alleles as they are vulnerable to the infection and over the homozygote recessive alleles who has sickle cell disease.

If a pin is .001 m wide how many red blood cells could you line up across a pin
tresset_1 [31]
According to the question, the width of a pin is 0.001m and the width of a red blood cell is 6-8 μm.
Width of pin in μm = 1000μm.
So approximately 1000/8 red blood cells can fit which is equal to 125 RBCs.

Answer: 125 RBCs

Which BEST describes the orbit of the Moon around Earth?
Solnce55 [7]
The statement that best describes the moon's orbit around the Earth is <span>c. elliptical with a period of about one month. Although its orbit is elliptical, the moon's orbit can be described as nearly circular because it has an eccentricity of 0.05. Moreover, it takes around 27.322 days for it to orbit around the Earth once.</span>
