In 1884, a bacteriologist named Christian Gram created a test that could determine if a bacterium had a thick, mesh-like membrane called peptidoglycan. Bacteria with thick peptidoglycan are called gram positive. If the peptidoglycan layer is thin, it's classified as gram negative.

Although there are no options but this investigation is a COMPARATIVE investigation
Explanation:
Scientific investigations aims at satisfying a curiosity or a way of explaining natural phenomena. There are three types of investigations viz: descriptive, comparative and experimental investigations.
Comparative investigation is a type of investigation that involves collecting data on different organisms, locations etc for the sole purpose of comparing. It aims at confirming if there is a relationship between i.e. similarities/differences. In this question, two species of squirrels are being observed for their similarities and differences i.e. the aim of the investigation is COMPARISON. Hence, it is an example of comparative investigation
Mitosis- which is also regular cell division
it cannot be meiosis as that cell division only occurs when babies are being made.
Because a gene pool represents the genetic diversity found within a population, populations are made up of different species so a gene pool is specific to one population
2^5 = 32
Each chromosome has 2 options during independent assortment (maternal on the right, and paternal on the left, or the opposite) and there are 5 chromosomes.
