SECTION 1: EVOLUTION, THEMES OF BIOLOGY, AND SCIENTIFIC INQUIRY
(Questions 1–25)
Question 1
Which of the following best describes the concept of "descent with modification"
as it applies to the diversity of life on Earth?
A) The idea that species are fixed and unchanging over time
B) The idea that all living organisms share a common ancestor and have changed
over time
C) The idea that organisms can spontaneously generate from nonliving matter
D) The idea that each species was independently created in its present form
,ANS: B
Rationale: Descent with modification is the central concept of evolution,
proposing that all living organisms share a common ancestor and have changed
over time through natural selection and other mechanisms, giving rise to the
diversity of life.
Question 2
Which of the following correctly lists the levels of biological organization from
smallest to largest?
A) Biosphere, ecosystem, community, population, organism, organ system, organ,
tissue, cell, molecule
B) Molecule, cell, tissue, organ, organ system, organism, population, community,
ecosystem, biosphere
C) Cell, molecule, tissue, organ, organism, population, ecosystem, community,
biosphere, organ system
D) Molecule, tissue, cell, organ, organism, community, population, ecosystem,
biosphere, organ system
ANS: B
,Rationale: The levels of biological organization from smallest to largest are:
molecule, cell, tissue, organ, organ system, organism, population, community,
ecosystem, and biosphere.
Question 3
Which of the following best describes the process of natural selection as proposed
by Charles Darwin?
A) The process by which organisms acquire traits during their lifetime and pass
them to their offspring
B) The process by which individuals with advantageous traits are more likely to
survive and reproduce
C) The process by which all organisms are created at the same time and do not
change
D) The process by which evolution occurs through random chance alone
ANS: B
Rationale: Natural selection is the process by which individuals with traits better
suited to their environment are more likely to survive and reproduce, passing
those advantageous traits to their offspring.
, Question 4
Which of the following statements best describes the relationship between
structure and function in biology?
A) Structure and function are unrelated in biological systems
B) The structure of a biological component determines its function, and the
function often influences the structure
C) Function determines structure only in animals, not in plants
D) Structure determines function only at the molecular level
ANS: B
Rationale: Structure and function are closely related in biology. The structure of a
biological component determines its function, and the function often influences
the structure through evolutionary adaptation.
