Answer:
A. The lens spreads light.
Explanation:
The convex lens will converge the light that passes through it. The direction of light will be bend to be closer to the middle point. This is the lens used for the eyeglass that treat people with hypermetropia. That is why the convex lens also called a converging lens or a plus lens. The strength of the convex lens depends on its focal length, index of the material used, and the radius of curvature.

A bomb calorimeter has a separate chamber to hold substances and can even measure heat gain or loss for reactions that do not occur in water.
I think it is gravitational pull
Answer;
-Negative feedback mechanism
Explanation;
-Negative feedback is a regulatory mechanism in which a 'stimulus' causes an opposite 'output' in order to maintain an ideal level of whatever is being regulated.
-For instance; the maintenance of homeostasis normally involves negative feedback loops. These loops act to oppose the stimulus that triggers them. For example, if your body temperature is too high, a negative feedback loop will act to bring it back down towards the set point, or target value (normal value).
