Answer:
In a pinhole camera, light passes through the pinhole to project an upside-down image onto the back of the box, and in the human eye, light passes through the lens to project an upside-down image on the back of the retina
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.
A community should use sustainable practices to produce food because "it protects the environment, farming communities and farmed species".
<u>Answer:</u> Option B
<u>Explanation:</u>
The practice of sustainable food production is a united network that integrates several components with the development of each and every individual covered in the food chain in order to protect the environmental, economic and social well-being of a community.
The advantages of such practice are production of less greenhouse gases, fossil fuel utilization is minimized and more dependent on human labor inspite of chemicals and energy-intensive technology. Sustainable farms conserve scarce water resources, encourage biodiversity and build healthy soil through composting and planting techniques that cover crops.
