Question 1

Which of the following best illustrates the biological theme of 'energy and matter flow' in living systems?

Accepted Answer

The breakdown of glucose during cellular respiration to produce ATP.

Question 2

Place the following in order from smallest to largest according to the hierarchy of biological organization: organelle, tissue, cell, organ, molecule.

Accepted Answer

Molecule, organelle, cell, tissue, organ

Question 3

A researcher studies how the interactions between the heart, lungs, and blood vessels contribute to oxygen delivery in mammals. This approach is best described as:

Accepted Answer

Systems biology

Question 4

Which of the following is an example of an emergent property?

Accepted Answer

The coordinated contraction of heart muscle cells producing a heartbeat

Question 5

Which statement best explains the relationship between structure and function in biology?

Accepted Answer

The structure of a biological component determines its function.

Question 6

Which of the following is NOT a difference between prokaryotic and eukaryotic cells?

Accepted Answer

Prokaryotic cells are always multicellular; eukaryotic cells are always unicellular.

Question 7

Which domain includes organisms that are often found in extreme environments, such as hot springs and salt lakes?

Accepted Answer

Archaea

Question 8

A scientist isolates a single-celled organism with a nucleus and mitochondria. To which domain does this organism most likely belong?

Accepted Answer

Eukarya

Question 9

Which of the following best describes reductionism in biological research?

Accepted Answer

Breaking down complex systems into simpler components to study them individually.

Question 10

Which of the following is the correct sequence of levels in biological organization from least to most complex?

Accepted Answer

Molecule, cell, tissue, organ, organism

Question 11

Which of the following scenarios best demonstrates the concept of emergent properties?

Accepted Answer

A network of neurons forming a brain capable of consciousness.

Question 12

Which of the following is a correct match between a biological level and an example?

Accepted Answer

Tissue – muscle

Question 13

Which of the following statements about the three domains of life is correct?

Accepted Answer

Archaea and Eukarya share a more recent common ancestor with each other than with Bacteria.

Question 14

A medical researcher is investigating how a mutation in a single gene affects the function of a protein, which in turn alters the physiology of an entire organ system. This research approach best exemplifies:

Accepted Answer

Reductionism, because it starts with a gene and examines its effects at higher levels.

Question 15

Which of the following is an example of how structure determines function in biology?

Accepted Answer

The double-helix shape of DNA allows it to be copied accurately during cell division.

Question 16

Which of the following best describes why the circulatory system is considered an organ system rather than an organ or tissue?

Accepted Answer

It consists of multiple organs working together to perform a function.

Question 17

Which of the following is a unique feature of prokaryotic cells compared to eukaryotic cells?

Accepted Answer

Lack of membrane-bound organelles

Question 18

A biologist is studying the effect of removing a single protein from a cell and observes that the cell can no longer divide. This is an example of:

Accepted Answer

An emergent property, because cell division depends on the interaction of many proteins.

Question 19

Which of the following best explains why viruses are not classified within the three domains of life?

Accepted Answer

Viruses lack cellular structure and do not carry out metabolism.

Question 20

Which of the following is a correct application of the systems biology approach?

Accepted Answer

Analyzing how all genes, proteins, and metabolites interact to regulate cell division.
