Natural selection disrupts the genetic equilibrium by favoring the genes for the traits that impart survival advantage to individuals.
Explanation:
Natural selection refers to the unequal survival rate of individuals of a population due to the presence of some beneficial adaptive genetic trait. These individuals are able to survive more and leave more progeny. Over generations, the population has increased number of these individuals leading to evolution of a population with different allele frequencies.
For example, the frequency of gene for antibiotic resistance in the bacterial population was increased once humans started using antibiotics to control the bacterial population. This led to the evolution of the bacterial population with antibiotic resistance.
Well for starters there's a sustainable increase in thyroid cancer after childhood exposure. It can also cause death and radiation in factories. Hope this does something for you
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate, and then release waste products.
An alimentary canal is a digestive tract that is complete and has two openings which are the mouth and the anus. On the other hand a gastrovascular is a digestive tract that has only one opening. The advantage of the alimentary canal is the fact that intake of food can still go on even during digestion. This will enable a more complete digestion.
Bone strength is influenced by changes in the structure (size and shape) and composition [cortical (compact) bone, trabecular (sponge-like) bone, amount of cartilage] of the bone. 6 A high peak mass at a young age and the decrease of bone loss at a later age are two ways to reduce osteoporosis risk.
