Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
Answer:
D. dehydration synthesis
Explanation:
Dehydration means removing water, and synthesis means building or creating something. Therefore, the synthesis of dehydration is defined as removing water to build something. This process occurs by removing a molecule of -OH (hydroxyl group) and a molecule of -H to form H2O or water. This results in the covalent bonding of two monomers (small molecules) to form a polymer (larger molecule).
Dehydration synthesis uses condensation in the process and when this continues for a long period of time, a long and complex chain is formed, such as those of disaccharide or polysaccharides. It is also responsible for storing excess glucose molecules as well as larger polysaccharides such as starch and glycogen.
Answer:
Coal
Explanation:
Coal is considered a nonrenewable resource, because it takes millions of years to form.
Answer:
Explanation:
The charge of an atom is the number of protons minus the number of electrons. Usually, these two numbers are equal, so the atom is neutral (charge of zero). Answer 8: An atom is defined as having the same number of electrons (negative charge), protons (positive charge) and neutrons (no charge).
