The correct answer is: Blood type in humans.
The blood type in humans or ABO blood type is controlled by a single gene (the ABO gene) with three types of alleles (multiple alleles), a, b, i. a and b alleles express a special dominance relationship called codominance, meaning that they together form AB blood type. A is dominant over i so they together give A blood type. B is is also dominant over I, giving the B blood type.
With the passage of time, the rock wall would be weathered under the impact of flowing water and would receede backwards.
Explanation:
Given details=
Water flowing at the pace of 2 to 3 feet per sec
It must be understood that flowing water act as an erosive agent here.
As the water flows, it carries with itself erosive tools which erode the rock surface. Since the speed of water is considerable, the erosion is quite significant. Due to the erosive action of the river, the rock wall would be continuously eroded starting from the tip and in turn, would recede backwards (in the upstream direction).
The right answer is C.invention
Contact lenses are placed directly on the surface of the eye to correct your eyesight.
They can correct myopia and hyperopia. They can also correct age-related astigmatism and hyperopia (presbyopia).
Their principle is the same as for glasses: they bend the light and redirect it to your retina to improve your eyesight.

It should be noted that the graphs illustrated how different PH affect the population of the species.
<h3>What is PH?</h3>
It should be noted that pH simply means the measure of how acidic or basic water is. It can be deduced that the range of the pH is from 0 - 14.
From the complete question, the graphs illustrated how different PH affect the population of the species. When the pH is either too low or too high, the aquatic organisms living in it will die.
