11) During photosynthesis, plants take in water and carbon dioxide from the environment and use
sunlight to fuel a series of chemical reactions that ultimately build small sugar molecules.
Which of the core concepts of biology is exemplified by photosynthesis?
A) Evolution
B) Structure and function
C) Information flow, exchange, and storage
D) Pathways and transformations of energy and matter
E) Systems
12) The phenomenon through which populations of organisms change over time due to mutation,
natural selection, and genetic exchange is
A) homeostasis.
B) growth and development.
C) reproduction.
D) biological evolution.
E) organization.
13) The protein elastin plays an important role in providing elasticity and resilience to many
tissues in the body. Elastin has elastic properties because of the way the protein can change
shape. In a relaxed condition, the protein has an overall coiled, or looped shape. When
stretched, the protein extends into a straighter, more linear form. When the stretching force is
removed, elastin recoils back into the relaxed form. Which core concept of biology does the
elastin protein exemplify?
A) Evolution
B) Structure and function
C) Information flow, exchange, and storage
D) Pathways and transformations of energy and matter
E) Systems
14) Children often resemble their parents. The transmission of an eye color gene from parent to
child is an example of which core concept of biology?
A) Evolution
B) Structure and function
C) Information flow, exchange, and storage
D) Pathways and transformations of energy and matter
E) Systems
