Answer:
Disruptive selection
Explanation:
Disruptive selection, also known as diversifying selection, describes changes in population genetics where extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups. In this more individuals acquire peripheral character value at both ends of the distribution curve.
Treatment
Meningitis is an infection of the membranes, meninges that surrounds and protects the central nervous system (the brain and spinal cord). Bacterial meningitis must be treated immediately with intravenous antibiotics and sometimes corticosteroids and, of course, the antibiotic depends on the type of bacteria causing the infection.
Prevention
First of all, to prevent the spread of bacterial meningitis it is important to practice good hygiene, such as frequent handwashing. Since the factors that increase the risk include spending time in communities (school, campus or college) because it spreads easily, children should be aware and vaccinated. As several types of bacteria can cause bacterial meningitis, a range of vaccines is wide (e.g. meningococcal vaccine, Hib vaccine).
