Accepted Answer

Ability to photosynthesize

Question 3

A scientist observes that a certain plant grows faster when exposed to blue light compared to red light. She hypothesizes that blue light increases the rate of photosynthesis. Which step should she take next according to the scientific method?

Accepted Answer

Formulate a prediction based on her hypothesis.

Question 4

Which of the following best illustrates the theme of 'structure and function' in biology?

Accepted Answer

The double helix structure of DNA allows it to store genetic information efficiently.

Question 5

Accepted Answer

Testable and falsifiable

Question 8

Which of the following statements about DNA is correct?

Accepted Answer

DNA is composed of a sequence of four nucleotides that encode genetic information.

Question 9

Which of the following best describes evolutionary conservation?

Accepted Answer

The preservation of certain characteristics across all organisms due to their fundamental roles.

Question 10

Which of the following is an example of inductive reasoning in biology?

Accepted Answer

Question 11

Which of the following best explains why a scientific theory is different from the everyday use of the word 'theory'?

Accepted Answer

A scientific theory is a well-supported body of interconnected concepts, while in everyday language, a theory often means a guess.

Question 12

Which of the following is NOT a step in the scientific method?

Question 14

Which of the following is an example of a real-world application of the theme 'information' in biology?

Accepted Answer

Using DNA fingerprinting to solve crimes.

Question 15

Which of the following best describes the difference between reductionism and systems biology?

Accepted Answer

Reductionism breaks complex processes into simpler parts, while systems biology focuses on emergent properties of the whole system.

Question 16

Which of the following is a correct statement about the three domains of life?

Accepted Answer

Bacteria and Archaea are both prokaryotic, while Eukarya includes all eukaryotic organisms.

Question 17

A researcher finds a molecule in a worm that is structurally similar to the human insulin receptor. What is the most reasonable hypothesis based on the theme of structure and function?

Accepted Answer

The molecule in the worm likely has a similar function to the human insulin receptor.

Question 18

Which of the following best describes the role of control experiments in scientific inquiry?

Accepted Answer

They allow scientists to isolate the effect of a single variable.

Question 19

Which of the following is an example of evolutionary adaptation?

Accepted Answer
