Question 1

Accepted Answer

Ability to move independently

Question 2

A scientist observes that a certain type of bacteria appears in sterilized broth only when exposed to air containing dust particles. Which hypothesis does this observation support?

Accepted Answer

Cells arise only from pre-existing cells

Question 3

Which of the following best describes a scientific theory?

Accepted Answer

An explanation for a very broad class of observed phenomena that is supported by a wide body of evidence

Question 4

In an experiment testing the effect of Antibiotic A on Bacteria Type A, which of the following is the best example of a control group?

Accepted Answer

Plates without Antibiotic A where Bacteria Type A is grown

Question 5

Which of the following statements about hypotheses is TRUE?

Accepted Answer

A hypothesis must be falsifiable, meaning it can be shown to be false by evidence

Question 6

Which of the following is an example of a null hypothesis ($$H_0) in a $$study comparing the average weight of tiger cubs born in the wild and in captivity?

Accepted Answer

$$H_0$$: The average weight does not differ between groups of cubs

Question 7

A student claims that because a hypothesis cannot be proven true, it is not useful in science. Which of the following best refutes this claim?

Accepted Answer

Hypotheses are useful because they can be tested and potentially falsified, which advances scientific understanding

Question 8

Which of the following best illustrates the process of biological inquiry?

Accepted Answer

Collecting observational and experimental data to test hypotheses

Question 9

Which of the following is a prediction that could be tested in Pasteur's experiment on spontaneous generation?

Accepted Answer

If cells come from only pre-existing cells, then no cells will appear in the swan-necked flask

Question 10

Which of the following is an example of a falsifiable hypothesis?

Accepted Answer

The sex of an alligator hatchling is affected by the temperature of the egg

Question 11

Why is it important for experiments to be replicable?

Accepted Answer

So that results can be confirmed by repeating the experiment under the same conditions

Question 12

Which of the following best describes the chromosome theory of inheritance?

Accepted Answer

Hereditary information is transmitted from one generation to the next via chromosomes

Question 13

A researcher wants to test if a new fertilizer increases plant growth. Which of the following is the best experimental design?

Accepted Answer

Grow identical plants with and without the fertilizer, keeping all other conditions the same, and measure growth

Question 14

Which of the following is an example of binomial nomenclature?

Accepted Answer

Panthera pardus L.

Question 15

Which of the following is a key difference between a hypothesis and a theory in science?

Accepted Answer

A theory is supported by a wide body of evidence and explains a broad range of phenomena, while a hypothesis is a testable explanation for a specific observation

Question 16

Which of the following best explains why scientific names are used in biology?

Accepted Answer

They provide a standardized way to refer to species across languages and regions

Question 17

Which of the following is an example of an experimental prediction?

Accepted Answer

If Antibiotic A is effective, then Bacteria Type A will not grow on plates containing Antibiotic A

Question 18

Which of the following is a real-world application of the cell theory?

Accepted Answer

Understanding that diseases like tuberculosis are caused by bacteria, which are single-celled organisms

Question 19

Which of the following best describes the process of natural selection as it relates to evolution?

Accepted Answer

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