Answer:
This process is called photosynthesis. The plants take carbon dioxide and water in the presence of sunlight to make oxygen and carbohydrate.
C. 20 because 39-19 is 20 so there are 20 neutrons and the atomic number is the same as number of protons and electrons.
Photosynthesis is the process in which light energy of the sun is converted to chemical energy. The oxygen so released is used in the respiration process to break down complex molecules and releases energy in the form of ATP molecules.

Answer:
The correct answer is - They have substances that counteract acids or bases to prevent the pH from changing
Explanation:
All living organisms including humans are water-based systems, which implies that they rely intensely upon liquid equilibria, particularly acid-base equilibria. Hence, all the acid-base and pH ideas we have talked about so far are critical to the chemistry of organic or biological systems.
This is particularly significant for enzyme, which are proteins that go about as catalysts for all major biological reactions. Most enzymes just work inside a specific pH range. Because all natural cycles are subject to pH, cells and creatures must keep up a particular and consistent pH so as to keep their compounds in the ideal condition of protonation they have specific substances that counteract the acid and base to maintain pH.
for instance:
The pH of the Cytoplasm is maintained by the phosphate ion
The pH of the blood is regulated by the bicarbonate ion
