Answer:
C. The rate of photosynthesis increases with an increase in carbon dioxide.
Explanation:
Photosynthesis, which is the process by which certain organisms obtain their food from the light provided by the sun, can be inhibited or promoted by certain factors. One of the reactants of the photosynthetic process is carbon dioxide (CO2), hence, an increase in the amount of carbon dioxide, increases the rate of photosynthesis.
According to this question, two areas with equal sunlight and available water are being described to have different levels or amounts of CO2. Area I has a high amount of atmospheric carbon dioxide while Area II has a low amount of atmospheric carbon dioxide. This means that Area 1 will undergo more photosynthetic activity than Area II.
Answer:
Positive phototaxis
Explanation:
"Phototaxis is called positive if the movement is in the direction of increasing light intensity and negative if the direction is opposite."
Pepsin enzymes can then digest dietary proteins in the lumen of the stomach. Pepsin in a protease digesting the proteins into smaller peptides. It is produced by the chief cells of the stomach in the form of a proenzyme called pepsinogen. A proenzyme or a zymogen is basically inactive and needs a biochemical change to become an active enzyme. This biochemical change is brought about by the acidic environment of the stomach by the secretion of the hydrochloric acid by the parietal cells in the stomach lining.
