Question 1

Which of the following is NOT considered a fundamental property of life according to modern biology?

Accepted Answer

Life is capable of spontaneous generation

Question 2

Which level of biological organization is directly above 'cell' and below 'organ' in the hierarchy shown in the study materials?

Accepted Answer

Tissue

Question 3

In biological taxonomy, which of the following sequences correctly orders the levels from most inclusive to least inclusive?

Accepted Answer

Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

Question 4

Which statement best describes a scientific theory in biology?

Accepted Answer

A scientific theory is a widely supported explanation for a broad class of observations, with both pattern and process components.

Question 5

Which of the following best illustrates 'descent with modification' as described by Darwin?

Accepted Answer

The gradual change in horse species over millions of years, as seen in the fossil record.

Question 6

Which evidence supports the concept that geologic time is vast?

Accepted Answer

Radiometric dating and sedimentary rock layers

Question 7

Transitional features in fossils provide evidence for which evolutionary concept?

Accepted Answer

Descent with modification

Question 8

Which of the following is a prediction of Darwin’s theory of descent with modification?

Accepted Answer

Species change through time and are related by common ancestry

Question 9

According to the study materials, what is the main mechanism by which evolution occurs?

Accepted Answer

Natural selection acting on variation among individuals in populations

Question 10

Which of the following best describes the process component of a scientific theory?

Accepted Answer

It explains the mechanism by which a pattern is produced in nature.

Question 11

If a population of giraffes has variation in neck length, and those with longer necks survive and reproduce more, which evolutionary principle is being demonstrated?

Accepted Answer

Natural selection

Question 12

Which of the following is NOT a valid line of evidence for descent with modification?

Accepted Answer

The idea that all species are immutable

Question 13

Which equation would you use to calculate the frequency of a dominant allele in a population, given Hardy-Weinberg equilibrium?

Accepted Answer

$$p + q = 1$$

Question 14

Which scenario best illustrates the 'law of succession' as described in the study materials?

Accepted Answer

Extant species in an area resemble extinct species found in the same region's fossil record.

Question 15

Which of the following statements about adaptation is most accurate?

Accepted Answer

Adaptations are traits that increase an organism's fitness in a particular environment.

Question 16

Which of the following is a misconception about evolution by natural selection?

Accepted Answer

Evolution always leads to more complex organisms.

Question 17

Which of the following best describes the relationship between mutation and evolution?

Accepted Answer

Mutation introduces heritable variation, which can be acted upon by natural selection.

Question 18

Which of the following is an example of a multi-step evolutionary process integrating mutation, selection, and adaptation?

Accepted Answer

A mutation in a plant leads to resistance to a new disease, and over generations, plants with the mutation become more common due to higher survival and reproduction.

Question 19

Which of the following best explains why the fossil record is important for understanding evolution?

Accepted Answer

It provides evidence of extinct species and shows how species have changed over time.

Question 20

Which of the following is a correct application of the concept of common ancestry?

Accepted Answer

Humans and chimpanzees share a more recent common ancestor than humans and dogs.
