a. parsimony; simplest; fewest
When selecting among multiple possible phylogenetic trees that fit our data, we commonly use the principle of <u>parsimony</u>, which means we choose the <u>simplest</u> possible hypothesis. In phylogenetic analysis, that means selecting the tree that represents the <u>fewest</u> evolutionary changes or mutations.
Explanation:
Phylogeny describes the evolutionary history of on organism or group of organisms.
A phylogenetic tree structure is used to describe the relationship between various organisms which have originated from common ancestors.
The Principle of Parsimony is best applied while constructing phylogenetic tree.
This principle emphasizes on simple observations on a phylogeny which requires only few changes or variations which explain for the difference between the phylogenic sequences.
This tree structure will only have few specific genetic variations or mutations or evolutionary changes which took place through new appearance of a trait or disappearance of an existing trait.
B. they are both unicellular
The presence of two peripheral efferent neurons in a pathway is typical of the autonomic division. The autonomic division is part of the vertebrate nervous system and this system is responsible for involuntary action regulation (regulation of the intestines, heart, and <span>glands).

Three question that are missing from given question are as follows:
Identify the problem(s) at hand.
Determine the cause of the problem(s).
Recommend solutions to the problem(s).
Answer:
The nesting area of ocean turtles could be saved and secured with the assistance of commitment of neighborhood individuals , maintaining a strategic distance from of beach fires during nesting season. Leave the enough beach area for the turtles to hatch their egg and nesting.
There ought to be negligible lighting close to the settling regions as arched turtles are attracted to light and they may wind up moving towards the city as opposed to the water. Local people could protect the hatching eggs from other wild creatures and winged animals by tagging them and keeping a nearby eye.
Beach region should be cleanup as the debri are the significant reason forever danger to the turtles and all other marine creatures.
