These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. "If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. The example we will use here is ice melting into water.

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.

Which of the following is an example of diffraction?
makkiz [27]

<u>Answer:</u>

You try to pick up a shell in the water but it isn't where it appears to be is an example of diffraction

<u>Explanation:</u>

Diffraction refers to the light bending that happens as the light passes about the edge of some object. How much bending takes place is found by the size of wavelength of light relative to that of opening. If the opening is larger than the wavelength of light, then bending will not be noticeable.

Since, light gets diffracted due to water hence the shell kept inside the water appears to be at a different position than where it actually is

Eric follows a vegetarian eating pattern, and he wants to know whether he needs to take any vitamin and mineral supplements. wha
Reil [10]

It would be most important for Eric to find out his <em>zinc, iron and vitamin B12 (or  riboflavin) levels, and ensure that he is obtaining adequate amounts of these vitamins and minerals through vegetarian sources </em>.

A vegetarian diet is typically low in zinc rich foods, since meat, shell fish and eggs are the most abundant sources of zinc. In order to ensure that he obtains sufficient zinc, Eric should make sure he consumes vegetarian zinc sources such as legumes, lentils, dairy, nuts and seeds on a daily basis.

Since iron and vitamin B12 are also difficult to obtain from vegetarian sources, Eric should consume iron rich foods such as spinach, kale, whole grains, broccoli, legumes,etc., on a daily basis. As for vitamin B12, daily supplementation of 2.4 μg is recommended for vegetarians. Alternatively, riboflavin fortified cereals and grains are also recommended to meet daily riboflavin requirements.
