Question 1

Which of the following best describes an emergent property in biology?

Accepted Answer

A property that arises from the interaction of parts within a system, such as the ability of muscle and nerve cells to produce coordinated movement.

Question 2

Which of the following statements correctly distinguishes between prokaryotic and eukaryotic cells?

Accepted Answer

Eukaryotic cells contain membrane-bound organelles, including a nucleus, while prokaryotic cells do not.

Question 3

Which domains of life contain prokaryotic organisms?

Accepted Answer

Domain Bacteria and Domain Archaea

Question 4

A scientist observes that a certain plant grows faster in sunlight than in shade. Which of the following is a testable scientific hypothesis based on this observation?

Accepted Answer

If a plant receives more sunlight, then its growth rate will increase.

Question 5

Which of the following is an example of artificial selection?

Accepted Answer

Humans breeding dogs for specific traits such as size or temperament.

Question 6

In the Rock Pocket Mouse example, what was the original source of genetic variation for dark fur color?

Accepted Answer

A gene mutation causing a base difference in the gene Mc1r.

Question 7

Which of the following best explains why viruses are not considered living organisms?

Accepted Answer

Viruses cannot reproduce or regulate their environment independently.

Question 8

Which of the following is a key difference between natural selection and artificial selection?

Accepted Answer

Natural selection is driven by environmental pressures, while artificial selection is driven by human choices.

Question 9

According to the scientific method, which of the following is the correct relationship between independent and dependent variables?

Accepted Answer

The independent variable is manipulated to observe its effect on the dependent variable.

Question 10

Which of the following questions can science answer?

Accepted Answer

How do certain traits help organisms survive in their environment?

Question 11

A population of beetles contains both green and brown individuals. Over time, birds eat more green beetles, and the population becomes mostly brown. Which process does this scenario best illustrate?

Accepted Answer

Natural selection

Question 12

Which of the following statements about mutations is supported by the Rock Pocket Mouse video?

Accepted Answer

Mutations are neither good nor bad; their effects depend on the environment.

Question 13

If a population of mice has a 1% competitive advantage due to a beneficial mutation, and the advantage is compounded annually, approximately how many years will it take for 95% of the population to have the trait? Use the formula for exponential growth: $$N = N_0$ e$$^{rt}$$, where N$ is the final amount, N_0$ is the initial amount, r$ is the rate, and t$ is time.

Accepted Answer

About 100 years

Question 14

Which of the following is NOT a requirement for a scientific hypothesis?

Accepted Answer

It must be subjective and based on opinion.

Question 15

Which of the following best explains why scientific knowledge is considered reliable, even though it changes over time?

Accepted Answer

Scientific results are based on carefully observed and recently recorded evidence, and consensus is built through repeated experiments.

Question 16

Which of the following is an example of a question that science cannot answer?

Accepted Answer

Is it morally acceptable to clone animals?

Question 17

Which of the following statements about the three domains of life is correct?

Accepted Answer

Domain Eukarya includes animals, plants, fungi, and protists.

Question 18

Which of the following best describes the control group in a scientific experiment?

Accepted Answer

The group that does not receive the experimental treatment and is used for comparison.

Question 19

Which of the following is a unique feature of eukaryotic cells compared to prokaryotic cells?

Accepted Answer

Presence of membrane-bound organelles

Question 20

Which of the following best illustrates the concept of evolution by natural selection?

Accepted Answer

A population of insects becomes resistant to a pesticide over several generations due to survival of individuals with a resistance gene.
