Question 1

Which of the following best describes a scientific question according to the criteria listed in the study materials?

Accepted Answer

A question that collects data, is repeatable, limited to the natural world, and leads to testable ideas.

Question 2

Which of the following is NOT one of the four major principles for making an argument for natural selection?

Accepted Answer

Random mutation always leads to adaptation

Question 3

A biologist is studying a group of organisms and wants to determine if they form a clade. According to the study materials, what is the defining feature of a clade in a phylogenetic tree?

Accepted Answer

A group that can be cut from the tree at a single branch point and includes all descendants of a common ancestor.

Question 4

Which of the following statements about the Tree of Life is supported by the study materials?

Accepted Answer

All species, both living and extinct, share a common ancestor at some point in life's history.

Question 5

Which of the following is the correct format for writing the scientific name of humans according to binomial nomenclature?

Accepted Answer

$$Homo sapiens$$

Question 6

A scientist is organizing biodiversity information and wants to use a system that emphasizes both the unity and diversity of species. Which system is she using?

Accepted Answer

Linnaean Taxonomy

Question 7

Which of the following best explains why phylogenetic trees are important in biological sciences?

Accepted Answer

They provide an efficient structure for organizing biodiversity information and help develop an accurate conception of evolutionary history.

Question 8

Which of the following is a correct statement about prokaryotes and eukaryotes based on the study materials?

Accepted Answer

Prokaryotes include Bacteria and Archaea, while Eukaryotes are a separate group.

Question 9

A population of beetles changes in color over several generations due to birds preying on the most visible individuals. Which evolutionary process is primarily responsible for this change?

Accepted Answer

Natural selection

Question 10

Which of the following scenarios best illustrates the principle of differential survival or reproduction?

Accepted Answer

Some individuals in a population survive and reproduce more successfully due to inherited traits.

Question 11

If two species share a recent common ancestor, what would you expect to see in a phylogenetic tree?

Accepted Answer

They branch from the same node.

Question 12

Which of the following is a real-world application of using phylogenetic trees?

Accepted Answer

Determining the evolutionary relationships among pathogens to track disease outbreaks.

Question 13

Which of the following best describes the process of classification in biology?

Accepted Answer

Organizing organisms into categories based on shared characteristics and evolutionary history.

Question 14

A student claims that all species alive today do not share any ancestors with extinct species. Based on the study materials, how would you respond?

Accepted Answer

This is incorrect; all species, living and extinct, share a common ancestor at some point.

Question 15

Which of the following is an example of a testable scientific question?

Accepted Answer

Do plants grow faster when exposed to blue light compared to red light?

Question 16

Which of the following is a correct statement about binomial nomenclature?

Accepted Answer

The genus name is capitalized and the species descriptor is not, and both are italicized.

Question 17

Which of the following best describes the role of variation in natural selection?

Accepted Answer

Variation provides the raw material upon which natural selection acts.

Question 18

A researcher is analyzing a phylogenetic tree and wants to identify the terminal taxa. What should she look for?

Accepted Answer

The tips at the end of the branches.

Question 19

Which of the following is a benefit of using Linnaean taxonomy in biology?

Accepted Answer

It provides a standardized system for naming and classifying organisms, emphasizing both unity and diversity.

Question 20

Which of the following best explains why all species are related in one great Tree of Life?

Accepted Answer

All species come from preexisting species and trace their ancestry back to a single common ancestor.
