Explanation:

Nuclear energy is created by the process of splitting atoms such as uranium atoms into smaller and lighter atoms and thereby converting the "lost" mass into heat. This lost mass is consequently used in production of electricity.

Solar Energy generation on the other hand is achieved by converting the radiation of the sun via solar panels and cells to electric current.

The disadvantages of nuclear energy over solar energy include the following :

a. SECURITY MATTERS : People who do not have very healthy intentions can easily target nuclear plants with the sole purpose of causing problems while uranium ( the chief ingredient for nuclear power generation) can be converted to nuclear weapons if the wrong people come in contact with it. This disadvantage obviously doesn't apply to solar energy generation

b. ACCIDENT: Nuclear energy isn't as safe as solar energy.

c. THE IMPACT ON THE ENVIRONMENT: Enrichment and mining of uranium are not processes that one can consider friendly to our environment. Open mining for uranium constitutes radioactive particles which can cause erosion and pollute water bodies or sources. This is not the case in solar power generation.

Answer: solar energy is renewable and less radioactive

Explanation: The fact that solar energy is renewable and less radioactive gives it an edge over nuclear energy. Nuclear energy is generated from fission of nuclear elements which are rare and are not readily available.

How did Claire's digestion reaction weights tell you that the problem was in her small intestine, and not in her stomach
RUDIKE [14]

Answer:

The reaction rate of the digestion helps in understanding which part of the digestive system having trouble in digestion especialy stomach and intenstine related.

It involves the fact that most of the enrgy or calories are get by the small intestine and also vitamins and minerals are absorbed by this part of the digestive system so if the small intestine is having problem the rate of digestion would be affected and and an individual could be malabosrbed.

If the problem lies in the stomach  it might show some effects of a poor digestion, however the rate of digestion would be better than if the problem lies in the small intestine.

And the producers have the largest population, which is why they are at the bottom of the pyramid of numbers. Finally they are at the bottom of food chains and webs because they store the most energy inside of them.
