Q: Which of the following is a correct representation of the process of natural selection?

$$\text{Heritable variation} \rightarrow \text{Differential success in reproduction} \rightarrow \text{Change in population characteristics}$$

Question 1

Which of the following is NOT one of the shared characteristics of all living organisms as described in the study materials?

Accepted Answer

They must be able to photosynthesize.

Question 2

According to cell theory, which statement is correct?

Accepted Answer

All cells are made from preexisting cells.

Question 3

Which scientist is credited with first observing 'animalcules' (single-celled organisms) using a microscope?

Accepted Answer

Anton van Leeuwenhoek

Question 4

The theory of evolution by natural selection states that:

Accepted Answer

Species change over time because individuals with advantageous traits are more likely to survive and reproduce.

Question 5

Which experiment disproved the hypothesis of spontaneous generation?

Accepted Answer

Louis Pasteur's swan-neck flask experiment

Question 6

Where is genetic information stored in cells according to the study materials?

Accepted Answer

In the chromosomes

Question 7

Which of the following best describes a scientific theory?

Accepted Answer

An explanation for a very broad general phenomenon supported by evidence.

Question 8

The chromosome theory of inheritance proposes that:

Accepted Answer

Genetic information is transmitted from one generation to the next via chromosomes.

Question 9

Which process is responsible for the transmission of genetic information from parent to offspring?

Accepted Answer

Replication

Question 10

If a population of beetles is exposed to a new predator, and over time the average color of the beetles shifts from light to dark, which concept does this best illustrate?

Accepted Answer

Natural selection

Question 11

Which of the following is a correct representation of the process of natural selection?

Accepted Answer

$$	ext{Heritable variation} ightarrow 	ext{Differential success in reproduction} ightarrow 	ext{Change in population characteristics}$$

Question 12

Which of the following statements about cells is FALSE?

Accepted Answer

Cells can spontaneously generate from non-living matter.

Question 13

A scientist observes that a certain trait in a population increases in frequency over generations. Which mechanism is most likely responsible for this change?

Accepted Answer

Natural selection

Question 14

Which of the following best explains why the swan-neck flask experiment by Louis Pasteur was important?

Accepted Answer

It demonstrated that microorganisms do not spontaneously generate but come from preexisting cells.

Question 15

Which of the following is an example of heritable information being passed from one generation to the next?

Accepted Answer

A child inheriting eye color from their parents.

Question 16

Which concept is illustrated by the following equation?

$$	ext{Variation} + 	ext{Inheritance} + 	ext{Differential Reproduction} = 	ext{Evolution by Natural Selection}$$

Accepted Answer

Theory of evolution by natural selection

Question 17

Which of the following is a direct result of the process of replication in living organisms?

Accepted Answer

Transmission of genetic information to offspring

Question 18

Which scientist's work led to the proposal of the chromosome theory of inheritance in 1902?

Accepted Answer

Sutton and Boveri

Question 19

Which of the following best describes the role of energy in living organisms?

Accepted Answer

Energy is required to stay alive and carry out life processes.

Question 20

A population of bacteria is exposed to an antibiotic. After several generations, most bacteria are resistant to the antibiotic. Which process best explains this outcome?

Accepted Answer

Natural selection
