The anatomy of the bone is what it is made up of; the physiology is how it is used by the body.
watt per square meter (W/m2).
Energy is absorbed to break bonds in mgcl, and to form bonds in cacl2. Thus, the correct option is A.
<h3>
How do chemical reactions occur?</h3>
The transformation that takes place in substances, wherein atoms rearrange themselves and alter their initial state, is what gives rise to chemical processes. As a result, chemical compounds alter and produce new molecules.
A replacement reaction is the sort of reaction implied by the chemical formula Ca + MgCl2 --- CaCl2 + Mg.
In this instance, energy is absorbed during the chemical reaction to break bonds in the reactants and build bonds in the products.

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.
