Question 1

Which of the following best explains why living organisms are said to 'fight against entropy'?

Accepted Answer

Living organisms maintain a high degree of organization despite the natural tendency toward disorder.

Question 2

Which of the following is NOT a fundamental characteristic of living things?

Accepted Answer

Ability to increase entropy in their surroundings

Question 3

A scientist observes that a car has organization, responds when you push start, and converts chemical energy to movement. Why is the car NOT considered alive?

Accepted Answer

It cannot reproduce or undergo development.

Question 4

Which statement about the scientific method is correct?

Accepted Answer

Experiments are designed to collect data that can support or refute a hypothesis.

Question 5

Why is the assumption of uniformity important in science?

Accepted Answer

It allows scientists to apply the same natural laws to events occurring at different times and places.

Question 6

Which of the following is a correct sequence of steps in the scientific method?

Accepted Answer

Question → Hypothesis → Prediction → Experiment → Conclusion

Question 7

Which of the following is TRUE about cell theory?

Accepted Answer

All living organisms are composed of membrane-bound cells.

Question 8

Pasteur’s experiment was designed to test which hypothesis?

Accepted Answer

Cells arise from cells and not by spontaneous generation.

Question 9

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

Accepted Answer

Individuals must vary in heritable characteristics.

Question 10

Artificial selection differs from natural selection in that:

Accepted Answer

Artificial selection involves humans choosing which individuals reproduce.

Question 11

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

Accepted Answer

Populations change over generations, leading to adaptation to their environment.

Question 12

Which of the following is NOT a function of metabolism in living organisms?

Accepted Answer

Increasing entropy within the cell

Question 13

Which of the following is a correct statement about genes?

Accepted Answer

Genes replicate faithfully but can occasionally mutate to new forms.

Question 14

Which taxonomic rank is the most specific?

Accepted Answer

Species

Question 15

Which of the following is a unifying idea in biology?

Accepted Answer

The cell is the fundamental structural unit in all living organisms.

Question 16

Which of the following is TRUE about eukaryotic cells?

Accepted Answer

They have a membrane-bound nucleus.

Question 17

Which of the following is a plausible reason why mutations are important in evolution?

Accepted Answer

Mutations create heritable variation that can be acted upon by natural selection.

Question 18

Which equation best represents the concept of entropy in a closed system?

Accepted Answer

$$\Delta S \u003e 0$$

Question 19

A population of plants is exposed to drought conditions. Over several generations, plants with deeper roots become more common. This is an example of:

Accepted Answer

Natural selection

Question 20

Which of the following is a real-world application of the scientific method?

Accepted Answer

Diagnosing why a car won't start by forming a hypothesis, making predictions, and testing them.
