Question 4

Which domain(s) consist(s) of prokaryotic organisms?

Accepted Answer

The domains consisting of prokaryotic organisms are Bacteria and Archaea. Eukarya consists of eukaryotic organisms.

Question 5

The best outgroup to use for resolving phylogenetic relationships of vascular plants is the ____ because all of its character states are considered ancestral.

Accepted Answer

Ferns are considered the best outgroup for resolving phylogenetic relationships of vascular plants because they possess character states that are considered ancestral compared to those found in seed plants (angiosperms, conifers, cycads, and ginkgophytes). This makes them useful for comparative studies to infer the evolutionary history of vascular plants.

Question 7

The systematics of today is very different from the systematics learned a generation ago. As a result, which statement is the least accurate?

Accepted Answer

The number of existing species is not known with certainty. Estimates vary widely, and new species are continually being discovered, making it impossible to have a precise count at any given time.

Question 9

Linear chromosome structure is a character unique to members of the domain(s) ____.

Accepted Answer

Linear chromosome structure is a characteristic unique to eukaryotes, organisms that belong to the domain Eukarya. Unlike eukaryotes, both archaea and bacteria typically have circular chromosomes.

Question 10

Question 11

A molecular clock is based on ____.

Accepted Answer

A molecular clock is based on a constant rate of mutation in DNA sequences, allowing scientists to estimate the time of divergence between different species by comparing their genetic material.

Question 12

To identify the optimal phylogenetic tree from multiple potential trees, many systematists use the ____ , which states that the simplest plausible explanation of any phenomenon is the best.

Accepted Answer

The principle of parsimony, often used in systematics for identifying the optimal phylogenetic tree, posits that the simplest explanation (in this case, the tree with the fewest evolutionary changes) is preferred. This approach minimizes the number of assumptions and changes needed to explain the observed data.

Question 13

Question 14

Gene sequences that evolve at a constant rate can be used to ____.

Accepted Answer

Gene sequences that evolve at a constant rate can be used as molecular clocks to estimate the time of divergence between two species by comparing genetic differences.

Question 16

Match between columns
                        Premises: highest level of taxonomic hierarchy

Accepted Answer

The Answer of synapomorphy and taxonomy and outgroup and cladistics is...

Question 17

To account for variations in the evolutionary rates at different genetic loci, the ____ compares alternative trees reflecting different rates of evolutionary change to identify the best evolutionary path.

Accepted Answer

The maximum likelihood method is used to account for variations in evolutionary rates at different genetic loci by comparing alternative trees and identifying the best evolutionary path based on statistical principles. This method allows for the incorporation of different rates of change across genetic loci, providing a more accurate representation of evolutionary relationships.

Question 18

The movement of genetic material between organisms by any mechanism other than descent is known as ____.

Accepted Answer

Horizontal gene transfer is the correct term for the movement of genetic material between organisms through mechanisms other than direct descent.

Question 19

Currently, taxonomic domains include ____.

Accepted Answer

The current taxonomic classification system recognizes three domains: Archaea, Bacteria, and Eukarya. These domains represent the highest level of classification, which organizes life primarily based on cellular organization and genetics.
