Question 1

Which of the following is NOT one of the five fundamental characteristics that define life?

Accepted Answer

Ability to photosynthesize

Question 2

Pasteur’s experiment with the swan-necked flask provided evidence against which theory?

Accepted Answer

Spontaneous Generation

Question 3

According to the Cell Theory, which statement is correct?

Accepted Answer

All organisms are made up of cells and all cells come from pre-existing cells

Question 4

Which scientist’s observations of 'animalcules' contributed to the development of the Cell Theory?

Accepted Answer

Antonie van Leeuwenhoek

Question 5

The Chromosome Theory of Inheritance states that hereditary information is encoded in units called genes, which are found on chromosomes. Which molecule primarily makes up chromosomes?

Accepted Answer

Deoxyribonucleic acid (DNA)

Question 6

Which of the following best describes the flow of genetic information in cells?

Accepted Answer

DNA $$\rightarrow$$ RNA $$\rightarrow$$ Protein

Question 7

A mutation occurs in the DNA of a cell. According to the Chromosome Theory of Inheritance, what is the most likely consequence?

Accepted Answer

The mutation may result in a different protein being produced, potentially altering a trait

Question 8

Which of the following is a requirement for evolution by natural selection to occur in a population?

Accepted Answer

Traits must be heritable and there must be variation among individuals

Question 9

Darwin’s concept of 'descent with modification' is best described as:

Accepted Answer

The process by which species change over generations and share common ancestry

Question 10

Which of the following scenarios best illustrates 'survival of the fittest' as described by natural selection?

Accepted Answer

A population of bacteria exposed to antibiotics, where only those with resistance genes survive and reproduce

Question 11

Which experiment provided direct evidence that cells do not arise spontaneously, but from pre-existing cells?

Accepted Answer

Pasteur’s swan-necked flask experiment

Question 12

If a population of insects develops a mutation that allows some individuals to survive a pesticide, what process will likely occur over generations?

Accepted Answer

The frequency of the pesticide-resistant trait will increase in the population

Question 13

Which of the following best explains why DNA comparison is used to determine evolutionary relationships among organisms?

Accepted Answer

DNA contains hereditary information that reflects shared ancestry

Question 14

Which of the following is a direct result of the process described by the equation $$	ext{DNA} ightarrow 	ext{RNA} ightarrow 	ext{Protein}$$?

Accepted Answer

Genetic traits are expressed through the production of proteins

Question 15

Which of the following statements is TRUE regarding the Chromosome Theory of Inheritance?

Accepted Answer

Genes are segments of DNA found on chromosomes

Question 16

A scientist discovers a new organism that is made up of membrane-bound cells, can reproduce, processes hereditary information, acquires energy, and evolves. According to the study materials, this organism is:

Accepted Answer

Alive because it meets all five fundamental characteristics of life

Question 17

Which of the following best describes the role of mutations in evolution?

Accepted Answer

Mutations create genetic variation, which can lead to new traits that may be favored by natural selection

Question 18

Which of the following is an example of information processing in living organisms?

Accepted Answer

A plant bending toward light due to changes in gene expression

Question 19

Which of the following is a direct application of the Cell Theory in modern medicine?

Accepted Answer

Using antibiotics to target bacterial cells without harming human cells

Question 20

Which of the following best illustrates the concept of 'descent with modification'?

Accepted Answer

A population of finches developing different beak shapes over generations due to changes in available food sources
