Evolutionary Theory of Aging describes t<span>he view that natural selection has not eliminated many harmful conditions and nonadaptive characteristics in older adults. N</span>atural selection is linked to reproductive fitness, which is present only in the earlier part of adulthood. According to evolutionary theory, possibly if some disease occurred earlier in development, it might have been eliminated many centuries ago.
The flying insects classically utilize high numbers of mitochondria in flight muscles. In addition, mitochondria are organelles within eukaryotic cells that yield adenosine triphosphate in which the foremost energy molecule used by the cell. For this reason, the mitochondrion is sometimes denoted to as the powerhouse of the cell. The mitochondria are originating in all eukaryotes which are all living things that are not bacteria or archaea. It is thought that mitochondria ascended from once free-living bacteria that were combined into cells.
The best answer is b - it is rigid.
The cell wall is defined as the rigid, outermost layer found in plants and also certain bacteria, algae and fungi. It is absent in animal cells.
The plant cell wall is made up cellulose which is a structural carbohydrate. The cell wall is rigid and thus offers structural support allowing plant such as trees to grow to great heights.
It also helps prevent water loss, helps protect against insects and pathogens and keeps the shape of the plant.
