Answer:
because they contain alternate forms called alleles
Explanation:
My guess is that fat-soluble toxins that may occur in freshwater ecosystems would most affect apex species in these ecosystems. This is because fat-soluble toxins are stored in the fat reserves of animals, and then bioaccumulate up the food chain. So in this case, most of the toxin is not secreted, but stored within the food chain, and bioaccumulates, with the concentration becoming higher the further up the food chain.
Answer:
If you can show me the answers I could help out but I can't see anything right now sorry
Photosynthesis produces both glucose (sugar) and oxygen as products in the chemical reaction. Plants use photosynthesis to take in sunlight, water, and carbon dioxide as reactants and produce glucose for energy and oxygen. The reactants for photosynthesis are light energy, water, carbon dioxide and chlorophyll , while the products are glucose (sugar), oxygen and water.
I hope this helps =)
