Answer: sedimentary rocks
An aqueous environment is made up of water molecules. The word aqueous means or pertains to water or dissolved in water. In an aqueous solution, water serves as solvent. Types of aqueous solutions are acids and bases.
D, think of it like a house.
The answer to 15 is 4 because cellular respiration in the process that produces ATP. Protein synthesis, photosynthesis, and digestion don't directly produce ATP. Carbon dioxide is a by-product of cellular respiration.
Looking at your answer to number 16, I think you might have confused cellular respiration with "regular respiration" or breathing. We breathe in oxygen and breathe out carbon dioxide because the mitochondria in our cells require oxygen to produce ATP, and release carbon dioxide as a byproduct.
Therefore, number 16 isn't cellular respiration. It's not happening within a cell, it's not producing ATP, and mitochondria aren't involved. Instead, it takes place in the lungs (because the alveolus is part of the lungs). You can see that carbon dioxide is being removed from the blood and oxygen is being added. This is the process of gas exchange.
