Chemistry exposes an individual to the study of matter and how the components of matter define everyday life and activities. Through the formal study of chemistry, one is able to acquire a theoretical grasp of the applications of chemistry. Additionally, elaborate and well-structured modules enable an individual to understand the theoretical structure of chemistry as well as the implications of the various applications of chemistry. Much emphasis was put on the means through which chemistry can be used to achieve sustainable and evidence-based practices in everyday activities. Chemistry is critical to the performance of normal activities which would not be possible in the absence of the comprehension of the processes of molecular bonding and reactions. For instance, organic chemistry enables individuals to comprehend the functions of molecules available naturally to achieve hygiene (Childs et al., 2015). This knowledge has been applied to the manufacture of soaps which has enabled the observations of apt hygiene standards (Childs et al., 2015). Additionally, the knowledge of chemistry has been applied in the extraction of various metals and minerals from their raw forms and metal ores to ready-to-use materials and components in daily life (Childs et al., 2015). This has enhanced the manufacturing and production industry which has seen a boom in innovations of machinery and equipment (Childs et al., 2015). The study of the combination of both organic and inorganic chemistry has additionally been used in the manufacture of protective creams and skin ointments (Childs et al., 2015). The manufacture if sunscreen heavily relies on the ability of its chemical components to reflect ultraviolet radiation, therefore protecting an individual’s skin.
The possession of DNA by mitochondria located outside the nucleus of a cell has laid basis to the endosymbiotic theory ( Workalemahu et al, 2017) . This is due to the fact that this theory suggests that mitochondria and chloroplasts were independent bacteria existing which through consumption would continue to thrive within other larger cells ( Workalemahu et al, 2017) . This theory is supported by the fact that the possession of DNA exhibits the independent properties of the mitochondria therefore suggesting that endosymbiosis would have resulted in the existence of the cells in larger cells in organisms. The human body only inherits maternal mitochondrial DNA during early development stages ( Workalemahu et al, 2017) . Female mitochondrial DNA is passed to offspring due to the fact that the male DNA is destroyed during the formation of the embryo ( Workalemahu et al, 2017) . Additionally, the female mitochondrial DNA is non-congruent with other cells hence it is passed on unaltered from females to offspring, both male and female.
