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.
The complete statement is "According to the biological perspective, personality is primarily determined by one’s genes" This is further explained below.
<h3>What are genes?</h3>
Generally, genes are simply defined as the biological fundamental unit of heredity that resides in a certain position on a chromosome.
In conclusion, biological personality is primarily determined by one’s genes.

The dissecting microscope is configured to allow low magnification of three-dimensional objects- objects larger or thicker than the compound microscope can accommodate. Furthermore, the two separate lenses of the binocular dissecting microscope allow one to see objects in three dimensions, i.e., in stereo
Answer:
seive played allow the food to pass to pjloem tube
Answer:
Rivers don't run straight because water flows in the least path of resistance
Explanation:
It is small disturbances in topography that set off reactions that alter the path of a river Any kind of weakening of the sediment on one side of a river due to animal activity it could also be because of soil erosion, or human activity can draw the motion of the water towards that side.
