An electron microscope is a microscope that uses beams of electrons instead of rays of visible light to form highly magnified images of tiny areas materials or biological specimens. Comparing light vs electron microscopes is made more complicated by the fact that there are different types of electron microscopes. Do not need to compound it in the form of essay? I know where exactly you can go to get the help with it. PrimeWritings site would be the best choice.

Discuss how variations within the population affect survival and fitness using an influenza outbreak as a model to support your
Tcecarenko [31]

During an influenza outbreak, many people get infected and die. However, part of the population acquires immunity and survives. This is due to variations in the genotype and phenotype among individuals in the population. Probably a particular phenotype confers resistance to influenza. Therefore, this population is able to grow and develop to maturity and reproduce. Their genes are therefore passed over to subsequent generations.
