Accepted Answer

Muscle tissue

Question 3

Which of the following best illustrates the hierarchical structural organization of the human body from smallest to largest?

Accepted Answer

Atom → Cell → Tissue → Organ → Organism

Question 4

Which of the following is NOT considered a requirement for life in living organisms?

Accepted Answer

Ability to photosynthesize

Question 5

If the Earth’s 4.5 billion year history were compressed into 24 hours, which event would most likely occur closest to midnight?

Accepted Answer

Appearance of modern humans

Question 6

Which organelle is primarily responsible for energy production in eukaryotic cells?

Accepted Answer

Mitochondrion

Question 7

A patient has a genetic disorder affecting the structure of their cell membranes. Which cellular function is most likely to be impaired?

Accepted Answer

Selective transport of substances into and out of the cell

Question 8

Which equation best represents the relationship between surface area ($A$) and volume ($V$) for a spherical cell of radius $r$?

Accepted Answer

$A = 4 \pi r^2$, $V = \frac{4}{3} \pi r^3$

Question 9

Which of the following best explains why multicellular organisms require specialized organ systems?

Accepted Answer

Phagocytosis

Question 11

Which of the following is a correct statement about the relationship between anatomy and physiology?

Accepted Answer

Anatomy and physiology are complementary; structure determines function.

Question 12

Which of the following is the best example of the principle 'form follows function' in the human body?
