Electron pairs , because the atoms become stable by gaining the electron pairs
Answer:
Option C. First, an animal eats another organism. Then, food is broken down into smaller molecules. Next, the animal's cells use molecules to make new cells.
Explanation:
When one animal eats another animal, the body of organisms is made of higher molecules such as carbohydrate, protein and lipids. These large molecules are broken down into simpler substances in the stomach such as glucose, amino acid and faty acid. These substances are absorbed by the body and release energy from them.
Answer: False
Explanation: Cell A is bacterium, prokaryotic while cell B is eukaryotic. Eukaryotic cells are bigger cells than prokaryotic cells thus the internal volume enlarge and the total cell membrane expands. Therefore, the ratio of total cell membrane to volume of cell A is not higher than that of the ratio of total cell membrane to volume of cell B.
