Biology 6/E Robert Brooker


Chap 1. An Introduction to Biology.

1) A community is composed of different populations of animals and plants.

⊚ true
⊚ false

2) All tissues are composed of cells.
⊚ true
⊚ false



3) A flower on a plant represents which level of organization?
A) atom
B) cell
C) organ
D) organism
E) population



4) Boa constrictors on an island are an example of a(n)
A) cell.
B) organ.
C) organism.
D) population.
E) ecosystem.



5) Molecules are made up of
A) atoms.
B) cells.
C) organs.
D) organisms.
E) populations.

,6) Which is the smallest of all levels of organization?
A) atom
B) cell
C) organ
D) organism
E) population



7) A community of organisms interacting with their physical environment is a(n)
A) population.
B) organism.
C) biosphere.
D) ecosystem.
E) macromolecular community.



8) In multicellular organisms, cells of the same type can associate with each other to form
A) atoms.
B) molecules.
C) macromolecules.
D) tissues.
E) populations.



9) Which level of organization is present in all life forms?
A) cell
B) tissue
C) organ
D) organelle
E) colony



10) Which level of organization includes all of the others in the list?
A) cell
B) tissue
C) organ
D) organism
E) population

,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

, 15) Vertical evolution, whereby living organisms evolve from a common ancestor ("tree of life"),
is the only mechanism of evolution on Earth.
⊚ true
⊚ false



16) All genetic mutations are harmful to an organism.
⊚ true
⊚ false



17) In the process of biological evolution, new species may evolve through exchange of genes
from one species to another. This process is called
A) proteome transfer.
B) horizontal gene transfer.
C) vertical evolution.
D) vertical descent with mutation.
E) genomic sciences.



18) How does evolutionary change occur?
A) Through the modification of characteristics in a preexisting population.
B) It may involve vertical descent with mutation.
C) It may involve horizontal gene transfer.
D) All of these choices are correct.
E) None of these choices are correct.



19) A variety of finch species within the Hawaiian Islands have acquired different types of beaks
needed for utilizing specific food resources. What is the likely process by which these
different species of finches came about?
A) vertical descent with mutation
B) horizontal gene transfer
C) an accumulation of harmful genetic mutations
