Experimental Design
A testable explanation to solve a problem
What is a hypothesis?
Cells that do not have a nucleus.
What are prokaryotic cells?
All living things are made of these.
What are cells?
This organism starts all food chains and food webs.
What is the producer?
Differences in traits within a population.
What is variation?
The variable that the scientist changes.
What is the independent variable?
These are two ecological reasons that bacteria are useful.
What are decomposers and producers?
An organism runs away when it hears a noise in the woods.
What is respond to the environment?
The accumulation of a toxin in the fatty tissue of an organism.
What is bioaccumulation?
This scientist said that organisms are born with traits that either help them survive or do not. Those individuals that have traits that help them survive will pass them onto future generations.
Who is Darwin?
The dependent variable.
What is the data that the scientist collects?
These bacteria have a thick layer of peptidoglycan.
What are gram + bacteria?
This characteristic means that all organisms must be able to maintain internal conditions.
What is homeostasis?
In a food chain involving producers, primary consumers, secondary consumers, and tertiary consumers, this level is the most affected by biomagnification.
What is the tertiary consumer?
Organisms must do these two things to be considered "fit."
What is survive and reproduce?
These are three requirements needed for graphing.
What is a title, axes labeled, and the graph spread out.
These are the three shapes of bacteria.
What are coccus, bacillus and spirillum?
The ability of an organism to undergo chemical reactions.
What is metabolism?
A species introduced into an ecosystem that causes harm to the organisms living there.
What is an invasive species?
What is the sharp teeth?
This graph is used when showing changes over the independent variable.
What is a line graph?
This is the area in which bacteria are unable to grow due to being killed.
What is the zone of inhibition?
This situation is when one organism produces two identical organisms.
What is asexual reproduction?
The type of growth exhibited when there are unlimited resources.
What is exponential growth?
An environment changes so that it is now very hot and dry and the remaining plants have very tough fruit that is hard to break into. In a species of birds, with hard tough beaks and long, thin beaks, this one would have the best chance of surviving and reproducing in this new environment.
What is the hard, tough beak?
