Answer:
sickle-cell anemia is not expressed
Explanation:
The heterozygote conditions shows that, the manifestation of theses condition is only possible if the carrier man(HbSHbA) get married to another heterozygote woman,( another carrier) so that the two recessive alleles are expressed as SS.
But as AS, this is not possible because of the non defective A-allele which is always dominant over the S
If the cytoplasm of a cell is at ph 7, and the mitochondrial matrix is at ph 8, this means that the concentration of H+ ion is tenfold higher in the cytoplasm than in the mitochondrial matrix.
<h3>What is pH?</h3>
pH means the power of hydrogen and it is a measure of the degree of acidity or alkalinity of a solution.
The pH tells us how acidic or alkaline a solution is. It ranges on a scale of 1 - 14.
- pH of 1 - 6 indicates acidity
- pH of 7 indicates neutrality
- pH of 8 - 14 indicates alkalinity
According to this question, the cytoplasm of a cell is at pH 7, and the mitochondrial matrix is at pH 8. This suggests that the concentration of hydrogen ion (H+) ion is tenfold higher in the cytoplasm than in the mitochondrial matrix.

I believe that the answer C because all the others make no sense and arnt true.<span />
Answer:
Weathering is very important to human life since it helps us to describe the formation of various landforms, leading to the formation of building materials like clay and the remnant of weathered rock like granitic tors can act as a tourist attraction.
It is ionic.Iodine is not dissolve in water because water is an extremely polar molecule , iodine exists in the diatomic form of I 2 and therefore non-polar and will not dissolved in water.
Iodine is highly soluble in non polar organic solvents like diethyl ether , ethanol, toluene but also least soluble in carbon tetrachoride and hexane because of weak induced dipole forces.
It is form charged transferred complex , most notably with the starch and these complexes , a fraction of the electronic charge is transferred to other molecule. This formation of these complex increase the solubility of iodine. Chloroform and carbon tetra-chloride.
