What is all regions of Earth where organisms live? biosphere
What is two or more atoms bonded together? molecule
What is the fundamental building block of all matter? atom
What is an individual that consists of one or more cells? organism
What is a substance that an organism needs for growth nutrient

What base do taxonomists tend to group organisms into biochemical traits
the same category?
In the scientific name, Pan paniscus; what does Pan Pan-genus; paniscus- species
represent and what does paniscus represent?
Which of the following organisms is a multi-celled oak tree
producer?
What is this single-celled or multicelled eukaryotic fungi
consumer that breaks down material outside itself, then
absorbs nutrients released from the breakdown.
What is the group that have no nucleus and are the most bacteria
numerous organisms on Earth?
What group is often found in extreme environments while archaea
having no nucleus, these organisms are closer genetically
to eukaryotes?
What does statistically significant mean? There is a very low probability that the difference in grades between the two groups
was due to chance or sampling error (usually less than 0.05)
The variables in the 2005 peacock butterfly experiment butterfly wing pattern color and sounds emitted
were
What is a control group an untreated group of individuals or subjects
Experimenter wanted to test effects of cigarette smoking control group

subset and results obtained from the whole?
What practice helps scientists avoid bias in their findings? publicly publishing their results
What is a theory? an explanation that is well documented and consistent with the evidence
What is a scientific theory? if a hypothesis stands after years of repeated testing, is consistent with data
gathered and helps make successful predictions
What is the Copernican model? the idea that Earth orbits the sun

The current rate of extinction is about how many times 1000
faster than normal?
