is it possible that two prokaryotic organisms show phenotypic similarities, but do not share close evolutionary relatedness? Explain your answer

Expert Solution

Phenotype is the term used in genetics for the composite observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior. Phenotypic relationships or phenotypic similarities mean that they have the same outward appearance genes in both prokaryotic organisms (such as bacteria). If these organisms have phenotypic similarities, it means that they have similar genes that produce these phenotypes, ie at the molecular level they have very closely related DNA. But the ability of bacteria to absorb DNA from their environment makes them quite able to integrate genes from other bacteria around them. Therefore, in such rare cases, the two prokaryotic organisms have similar phenotypic similarities but do not share evolutionary relationships.

Discuss TWO essential biological functions that prokaryotic organisms and eukaryotic organisms are able to perform using each type of transport. Are there ways in which the cell membrane of a prokaryotic organism or cell functions differently from a eukaryotic organism using either of these methods of transport? You may need to look around into passive and active transport uses in prokaryotic and eukaryotic cell membranes for this response.

How do you tell whether two genes are linked based on the phenotypic results of offspring from a dihybrid cross? If the genes are linked, certain combinations of phenotypes will not be observed as often among the offspring of a dihybrid cross If the two genes are on different chromosomes, all the offspring will look like the parents Linked genes will result in mutations being expressed only in male offspring Ifthegenesarenotlinked, you may calculate offspring ratios using Punnett squares If...

Draw the two possible ways to show Economic Growth on the Aggregate Supply and Demand Curve (each method should be shown on a separate graph). What are the “side effects” that accompany Economic Growth on each graph; under what circumstances is each bad? Each portion of an explanation should be a minimum of 5-6 sentences each.
