Answer:
A carbohydrate is an organic compound such as sugar or starch, and is used to store energy. Like most organic compounds, carbohydrates are built of small, repeating units that form bonds with each other to make a larger molecule. In the case of carbohydrates, the small repeating units are called monosaccharides.
Answer:
Through different studies scientist have quantified the amount of energy that moves to the next trophic level. Most of the energy is used for metabolic processes and released as heat to the environment.
The amount of energy left for the next level is around 10%, if a herbivore takes 1,OOO Kilojoules the energy left for the next level would be around 100 Kilojoules, this explains why you cannot find a food chain with more than 7-8 levels (ocean) on land is usually between 4-6 levels.
I believe the answer is C) How does a change in temperature affect the reproduction of crayfish?
The concentration of H+ ion (pH) could influence the structure of protein, which might inactivate some enzyme of an organism and alter their metabolism. All research questions beside option C is related to the pH. Buffer solution will provide an protection that will makes the pH become more stable. Acid rain contains acid which will decrease the pH of the surrounding environment.
Well if you have any plants on your home identify them and see what they do.
Alo vera is good to keep in your room, it helps with the air your room and helps you sleep.
