Answer:
Explanation:
A microscope is an instrument which is used to see the objects which are tiny and difficult to observe through naked eye. The microscope magnifies these objects and enlarge their size. It has two lenses that are ocular and objective.
The magnification for 10X ocular lens and the 40X objective lens is expected to produce the total magnification of 400X (10 x 40 = 400).
Destruction of myelin will affect the nerve and there will be the less conduction of electrical impulses from the brain to other parts of the body and the nerve signal sent to the brain are delayed. These damaged nerve areas form sclerosis which disrupts the signalling capacity of the nerve. This may occur due to genetic defects, infectious agents, auto immune reactions and trauma.
It is known as structurlism
The parental phenotype is the mother's free earlobes (Ff) and the father's nonfree earlobes (ff).
<h3>What genotype and phenotype?</h3>
The genotype refers to the information present in an individual's genome. Unlike the phenotype, it is not observable and rarely changes. The phenotype, in turn, depends on a combination between our genotype and the environment and can be defined as the observable characteristics of an individual.
With this information, we can conclude that the parental phenotype is the mother's free earlobes (Ff) and the father's nonfree earlobes (ff).
