UNIT I: CHEMISTRY
Question 1: Which of the following best exemplifies the core concept of "structure and
function" as described in Chapter 1?
A) A population of finches evolving different beak sizes over generations.
B) The coiled shape of the elastin protein allowing it to stretch and recoil.
C) The flow of genetic information from DNA to RNA to protein.
D) The cycling of carbon through the biosphere.
Correct Answer: B) The coiled shape of the elastin protein allowing it to stretch and
recoil.
The core concept of structure and function states that a biological structure determines
its function. The coiled structure of elastin directly enables its elastic function. Option A
describes evolution, Option C describes information flow, and Option D describes
energy and matter transformations.

Question 2: A community is composed of different populations of animals and plants.
A) True
B) False
Correct Answer: A) True
A community in ecology is defined as an assemblage of different populations of species
living and interacting in the same area. This includes all plants and animals.
Question 3: All tissues are composed of cells.
A) True
B) False
Correct Answer: A) True
The cell is the fundamental unit of life. In multicellular organisms, cells of the same type
associate to form tissues. Therefore, all tissues are composed of cells.
Question 4: A flower on a plant represents which level of organization?
A) atom
B) cell
C) organ
D) organism
E) population
Correct Answer: C) organ
An organ is a structure composed of two or more types of tissues that performs a
specific function. A flower is composed of different tissues (e.g., epidermal, vascular,
reproductive) working together for reproduction.
Question 5: Boa constrictors on an island are an example of a(n)
A) cell.
B) organ.
C) organism.
D) population.
E) ecosystem.
Correct Answer: D) population.
A population is a group of individuals of the same species living in the same area at the
same time. The boa constrictors on the island represent a population.
