<span>A single tree absorbs tons of carbon dioxide in its 30-year life cycle and it releases a ton of oxygen. The free nitrogen from the atmosphere is captured by the nitrogen-fixing bacteria and it converts nitrogen into nitrates and nitrites which is then absorbed by the plants. Trees, like all organisms, grow by adding mass (biomass). Carbon is the central ingredient in making that new biomass. Tree biomass is comprised of all parts of the tree; leaves, stems, branches, roots, tree trunks. The biomass of the woody tissue in the tree pictured on the right is made mostly of cellulose, a carbon compound. In a process called carbon fixation, plants transform CO2, an inorganic carbon compound into organic carbon compounds.</span>

From what I can tell, The answer is either A or B. Mammals have what is called an Endoskeleton, which means that their skeletons are inside their bodies. A way to remember this is Exo- is similar to exit and when you exit something then you are going outside. Endo- sounds like into, which can relate to being on the inside. Insects have Exoskeletons, which are made from Chitin. Now Agonists are also called Prime Mover muscles, which means they are practically the same thing.
