Answer:

Do not put chemicals back into reagent bottles; returning an unused chemical to a container risks contamination. Extra material must be placed in the appropriate chemical waste container. Whenever possible, share excess material with a neighbor, but do not return it to the original container.

ValentinkaMS [17]

Answer:

The correct answer is B. In the human eye, the greatest amount of refraction occurs when the light passes from the air into the cornea.

Explanation:

The ocular refraction refers to the refraction that occurs in the light coming from the objects when crossing the different parts of the eye, causing the images to concentrate on the retina.

When the light rays, after crossing the cornea and the lens, are projected on the retina at a single point creating a clear image that is transmitted to the brain for processing, we talk about normal refraction.

Which compound is a metabolic intermediate of the light-independent reactions in photosynthesis?
timama [110]
<span>Light dependent reactions require an actual source of light, and this is from the sun, for energy to carry out the first stage of photosynthesis. They need solar energy to split a water molecule in order to obtain electrons from hydrogen to be used in fueling photosynthesis. Light independent reactions do not require a light source for energy but rather they use energy that was created by the light dependent reactions to complete the process of photosynthesis in which different carbohydrates for the plant are made.</span>
