B. Populations are a group of the same species in a place at the same time.
Explanation:
cause: the hydrogen-bonds. each water molecule is held away from its neighbors at a distance equal to the length of hydrogen bonds
effect: when water has been frozen it turns to ice
<u><em>-Describe how food is broken down to make ATP.</em></u>
Digestion breaks down food into smaller molecules that can be used to make ATP.
- Different foods have different amounts of calories, which indirectly related with how much ATP each type of food can make.
- Carbohydrates are the most commonly broken down molecule to make ATP. The breakdown of the simple sugar glucose yields about 38 molecules of ATP.
<u><em>-Describe the process of cellular respiration. What are the products and the reactants?</em></u>
During cellular respiration, the glucose and oxygen combine together to form new products: Carbon dioxide molecules & water molecules. ATP is produced as the form of energy that can be used for other cellular processes. The reactants of photosynthesis are the products of cellular respiration and the reactants of cellular respiration are the products of photosynthesis.
