What is the relationship between food intake and physical activity?
elena-14-01-66 [18.8K]
Because we can't take in light energy directly, we consume plants. Plants convert light energy into chemical energy through the process of photosynthesis. So when we eat plants, we get the chemical energy stored in the carbohydrates, which fuels all our physical activity.

Explain each of the following, giving a named example in each case:
gogolik [260]
(a) solute = substance (solid or liquid) in lesser amount, which will [dis]solve into the solvent

(b) solvent = substance (liquid) in larger amount, which [dis]solves the solvent
it's dissolvability is called "solvency"
water is known as the universal solvent because it is abundant on Earth and has a high solvency

(c) solution = the combination of solvent + solute
depending on the saturation of solute within solvent, the solution may appear clear, like the solvent

**think of warm sugar-water (solution), when all the sugar (solute) dissolves into the water (solvent), the solute seems to have disappeared
