Ammonia-NH3
NEXT QUESTION
Geologic Time - 300
If 1.0 g of a radioactive isotope had a
half life of 1 billion years, how much
would be left after 3 billion years?
Answer:
0.125 g
NEXT QUESTION
Geologic Time - 400
What organism was most
helpful in creating an
environment on land that was
Answer:
habitable?
Photosynthetic
bacteria.
NEXT QUESTION
Geologic Time - 500
How are radioactive isotopes used to
determine the age of material ?
Answer: Radioactive isotopes decay at a specific
rate. The rate is known as its half-life. This is the
amount of time it takes for ½ of the material to
decay.

type of evidence?
NEXT QUESTION
Evidence - 400
Anatomical structures that have a similar
function, but did not evolve from a recent
ancestor are called what?
Answer:
Analogous structures
NEXT QUESTION
Evidence - 500
List three types of Answer:
morphological
Vestigial,
evidence for
Homologous,
and
evolution and one
example of each. Analogous structures.
Examples will vary.
NEXT QUESTION
The theories of life - 100
The idea that living
things could arise
from non-living
material is called
what?
Answer:
Spontaneous
generation.
NEXT QUESTION
The theories of life -200
What is
endosymbiosis?
Answer:
When a prokaryotic cell
with heterotrophic
characteristics
engulfed(endo) an
autotrophic cell. They lived
in harmony, (symbiosis).
NEXT QUESTION
The theories of life - 300
How was Louis
Pasteur’s experiment
to disprove
spontaneous
generation different
from either Francesco
Redi’s or Lazarro
Spallanzani’s?
Answer:
Louis had an
experimental flask
that was open to the
air containing the
“Vital Force”with a
swan neck. The broth
did not support life.
NEXT QUESTION
The theories of life - 400
What did Miller
and Urey’s
experiment
demonstrate?
Answer:
That early
atmospheric
gases could
have formed
organic
compounds.
NEXT QUESTION
The theories of life - 500
Define natural
selection
Answer:
Organisms that are
more adapted to an
environment will survive
and reproduce to pass
on those traits to their
offspring.
NEXT QUESTION
Natural Selection - 100
Will evolution occur if organisms mate
randomly? Explain your answer.
Answer: No. There is no selection for the better
trait. Unwanted traits, such as poor health,
may be inherited.
NEXT QUESTION
Natural Selection - 200
Why will a small
population
evolve faster
than a larger
population?
NEXT QUESTION
Answer: It takes
more time to see
genetic changes
in the larger
population.
Natural Selection - 300
The change in the
allele frequency
of a population
over time due to
random chance
is called what?
Answer:
Genetic drift
NEXT QUESTION
Natural Selection - 400
Answer:
The introduction
of new alleles
into a population
is called what?
Gene Flow
or immigration.
NEXT QUESTION

The process by which
unrelated organisms come to
look like one another is called
What?
Answer:
Convergent evolution.
NEXT QUESTION
First life forms - 100
What is the
significance of
the experiment
Urey & Miller
performed?
Answer:
They were able to create
organic compounds from
inorganic compounds in
conditions that replicated
Earth’s early atmosphere.

significance
of coacervates
and
microspheres?
• Cell like structures,

What is the
difference between
chemosynthesis and
photosynthesis?
• Answer:Both are
capable of creating

What role did cyanobacteria have in
changing the early Earth’s
