Out of the statements presented regarding the skeletal system, the last one would be the only true statement which says that there are 3 components to the sternum bone.
For the number of vertebrae that cover the spinal cord, there are around 31 segments that have it. For the pairs of ribs, there are 12 pairs of it. There are also 14 major facial bones. As for the components of the sternum bone, there are 3 components which are as follows: the manubrium, the body, and the xiphoid process.
The process of cellular respiration, carried out by all living organisms, involves the catabolic break down and conversion of carbon containing molecules especially glucose (6-carbon) into ATP and energy yielding compounds such as NADH and FADH2. This energy helps drive cellular processes for daily bodily functions.
C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP
Decomposition involves the conversion of living matter into simpler compounds by the action of special organisms called decomposers. This group principally includes bacteria and fungi. Bacteria and fungi degrade matter with the help of their enzymes and release nutrients into the soil. This process is a rich carbon and nutrient source for the plants and other soil borne organisms.
Fossilization is the process of preservation of living organisms in the form of rocks or sediments. Over millions of years and under intense pressure and temperature, these remains are converted into rich carbon sources such as coal, natural gas and oil. Therefore, this process converts carbon in the living system to fossil fuels.
