<span>Human skin color variations are primarily being determined by the type and amount of melanin pigment which is the skin.
The reason is the amount of melanin present, pigment present which determines the color of skin the more the melanin the more dark color they are.
Human skin color variation is likely evolved in response to differences in intensity of sunlight around the world. Reason being it has been developed because of different exposure of humans to the varied environment during migration. Human skin color variation evolved recently in hominid evolution.</span>
Answer:
Evidence: During photosynthesis, plant cells use sunlight to synthesize food. This is followed by cellular respiration, which converts the products of photosynthesis into chemical energy. Though animal cells do not use photosynthesis, they still perform cellular respiration in virtually the same way. Plant cells are the producers of glucose, and animal cells are the producers of oxygen, these are both reactants in the process of cellular respiration. The products of cellular respiration include carbon dioxide and water. The plant cells are consumers of animal cells waste products.
Explanation:
Claim: Both plants and animals perform cellular respiration
Answer:
Mitochondria is the Powerhouse of the cell.
Explanation:
You use your muscles for basically everything you do. So, it wouldn't be more surprising if the muscles need more energy. You need them to have more energy or you wouldn't be able to do anything.
