Answer:
Disruptive selection
Explanation:
Disruptive selection, also known as diversifying selection, describes changes in population genetics where extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups. In this more individuals acquire peripheral character value at both ends of the distribution curve.
C.)Pleiotropy is the effect of a single gene on more than one characteristic.....
Answer:
Such transport mechanism is called<u> Antiport.</u>
Explanation:
The production of hydrochloric acid (HCl) by the parietal cells requires the activity of the
enzyme, carbonic anhydrase.In the presence of carbonic anhydrase CO₂ and H₂O are converted to HCO⁻ and H⁻.
The newly generated proton (H+
)s transported into the lumen of the stomach via the e H
₊₋K
+ATPase (called the proton pump)Concurrently, HCO₃
⁻ exits from the basal surface (blood side) of the parietal cell via the HCO₃⁻
₋ Cl antiporter.
The chloride ionneeded to form HCl, enters the parietal cell from the blood via the HCO₃⁻₋Cl⁻ antiporter and exits at the luminal side by the Cl⁻ channel. Once within the lumen of the stomach, cl⁻ combines with H⁺to form HCl.
The luminal K⁺ that is needed to maintain the activity of the proton pump(H⁺₋K⁻ATPase)enters the parietal cells from the stomach lumen by the H⁺₋K⁺ + ATPase and is then recycled back into the lumen of the stomach by the K⁺ channel.

hydroponic farming is when you try to grow plants without soil, Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The Farmers plants could have been daying at the same rate because some plant need dirt, or mabye the root were just to long.
