Question 2

Which of the following is NOT considered a characteristic of living organisms?

Accepted Answer

Ability to remain unchanged over generations

Question 3

Charles Darwin developed his theory of evolution primarily based on observations made during his voyage to which location?

Accepted Answer

The Galapagos Islands

Question 4

Which of the following is the best definition of a scientific theory?

Accepted Answer

A best explanation of an event observed in the natural world that has been tested and supported by evidence.

Question 5

Natural selection is best described as:

Accepted Answer

The process by which the best traits in a population survive and are passed on to the next generation.

Question 6

Which of the following is a real-world example of natural selection?

Accepted Answer

The development of antibiotic-resistant bacteria in hospitals.

Question 7

Which of the following is NOT an area of evidence supporting the Theory of Evolution?

Accepted Answer

Astrological predictions

Question 8

A group of organisms with similar traits that can interbreed and produce fertile offspring is called a:

Accepted Answer

Species

Question 9

Which of the following pairs are considered the same species according to the biological species concept?

Accepted Answer

European human and African human

Question 10

Which process is responsible for the accumulation of change in a population over time?

Accepted Answer

Natural selection

Question 11

Which of the following is a correct display of scientific data?

Accepted Answer

Graphs

Question 12

What is the importance of a scientific name in biology?

Accepted Answer

It allows scientists to communicate clearly about specific organisms worldwide.

Question 13

Which of the following is an example of an endemic species?

Accepted Answer

A species found only on the Galapagos Islands.

Question 14

Which equation would you use to calculate the percentage of a specific isotope in a fossil sample?

Accepted Answer

$$\frac{	ext{Amount of isotope}}{	ext{Total amount of all isotopes}} 	imes 100$$

Question 15

Which of the following best explains why the Galapagos Islands have unique species not found elsewhere?

Accepted Answer

The islands are volcanic and isolated, allowing species to evolve independently from mainland populations.

Question 16

Which of the following is a mechanism for evolution described by Darwin?

Accepted Answer

Natural selection

Question 17

Which of the following is a correct statement about populations?

Accepted Answer

A population consists of individuals of the same species living in the same area at the same time.

Question 18

Which of the following is NOT a valid scientific process?

Accepted Answer

Assumption without evidence

Question 19

Which of the following is a plausible reason why mules are not considered a species?

Accepted Answer

Mules are sterile and cannot produce fertile offspring.

Question 20

Which of the following is a correct application of the concept of adaptation in a population?

Accepted Answer

A population of insects develops longer ovipositors over generations to survive colder winters.
