Accepted Answer

Structure determines function at all levels of biological organization.

Question 2

Which of the following is a key difference between prokaryotic and eukaryotic cells?

Accepted Answer

Prokaryotic cells lack a nucleus and membrane-bound organelles.

Question 3

Which process best describes the flow of genetic information from DNA to protein?

Accepted Answer

Transcription $$\rightarrow$$ Translation $$\rightarrow$$ Protein folding

Question 4

Which of the following best describes the role of producers in an ecosystem?

Accepted Answer

They convert sunlight into chemical energy through photosynthesis.

Question 5

Why is energy flow in an ecosystem described as 'one-way', while chemical cycling is 'cyclic'?

Accepted Answer

Energy enters as sunlight and exits as heat, while chemicals are reused.

Question 10

Which of the following best explains why DNA is considered the universal genetic language?

Accepted Answer

All organisms use the same four nucleotides in their DNA.

Question 11

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

Accepted Answer

Predicting that if all organisms are made of cells, then a new organism discovered will also be made of cells.

Question 12

Which of the following is a correct statement about natural selection?

Accepted Answer

It increases the frequency of traits that enhance survival and reproductive success.

Question 13

A controlled experiment is one that:

Accepted Answer

Tests only one variable at a time, keeping all other variables constant.

Question 14

Which of the following is an example of a real-world application of genomics?

Accepted Answer

Question 15

Which of the following best describes the process of chemical cycling in an ecosystem?

Accepted Answer

Chemical elements are reused and recycled among living and nonliving components.

Question 16

Which of the following is a correct example of how evolution explains both the unity and diversity of life?

Accepted Answer

All mammals have the same limb structure, but these limbs are adapted for different functions.

Question 17

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

Accepted Answer
