EXAM SOLUTION GRADED A+
List the characteristics of life (9). - CORRECT ANSWERS Order, Response, Reproduction,
Adaptation, Growth and development, Regulation, Homeostasis, and Energy processing.
Order - CORRECT ANSWERS Organisms are highly organized. Even cells perform specialized
functions.
Sensitivity and Stimuli Response - CORRECT ANSWERS Movement toward a stimulus is
considered a positive response, movement away from a stimulus is considered a negative
response.
Reproduction (2) - CORRECT ANSWERS One celled organisms reproduce by binary fission,
budding, or cloning. Multicellular organisms reproduce by asexual or sexual reproduction.
Multicellular organism - CORRECT ANSWERS Organism made up of many cells.
Diploid vs. Haploid - CORRECT ANSWERS Diploid: Human cells having 2 copies of each
chromosomes.
Haploid: Human cells with only 1 copy (half the DNA).
DNA and RNA are macromolecules.
T or F - CORRECT ANSWERS T.
Adaptation - CORRECT ANSWERS All living organisms exhibit a "fit" to their environment.
Survival of the fittest.
List the hierarchy of life (13). - CORRECT ANSWERS Atoms > Molecule > Organelles > Cells >

Molecule - CORRECT ANSWERS Most fundamental and stable components of matter.
Macromolecules - CORRECT ANSWERS These are large molecules that are formed with
combined smaller units (monomers).
Organelle - CORRECT ANSWERS Sub-unit of a cell and is a membrane bound compartment
within it.
Cell - CORRECT ANSWERS Basic unit and building block of life that is bound by a cell
membrane and has a nucleus.
Cell theory (3) - CORRECT ANSWERS The idea that all living things are composed of cells,
cells are the basic units of structure and function in living things, and new cells are produced
from existing cells.
Growth and Development - CORRECT ANSWERS Organisms grow and develop according to
specific instructions coded for their genes.
Regulation - CORRECT ANSWERS Functions such as transport of nutrients, response to
stimuli, and coding environmental stresses.
Homeostasis (4) - CORRECT ANSWERS The ability of an organisms to maintain constant
internal condition. Negative feedback is the normal response, which stops the initial
response. Positive feedback increases the initial response. This could be deadly except in
certain situation.
Movement is a property of life.
T or F - CORRECT ANSWERS F.
Is a virus considered living (3)? - CORRECT ANSWERS No, because even though it has DNA
and RNA, it cannot reproduce without a host cell and has no cellular structure. It is an
intracellular parasite.
