Within a decade of the introduction of a new insecticide, nearly all of

dose. The most likely explanation for this immunity to the insecticide
is that ____.

eating the insecticide caused the insects to become resistant
to it

eating the insecticide caused the insects to become less
resistant to it

population and that provided immunity to the insecticide

Part 2: Finding
Connections
Finding Connections
What 2 macromolecules
are found in ALL living
organisms that allow for
the continuity of life?
• Nucleic Acids
• Proteins
Finding Connections
Explain what the word
fitness means as it
pertains to natural
selection.
• Fitness is the ability to obtain resources in
order to survive and reproduce.
Finding Connections
Is it ok to say that a scientific
theory is just a theory?
( YES / NO )
Explain the difference between
a scientific theory and the
venacular use of the term
theory.
• No
• A scientific theory is an overarching
explanation of a natural occurrence that is
heavily supported by evidence and has been
tested many times by many different
scientists. A theory in the vernacular sense is
an idea, believe, or philosophy that may or
may not be supported by scientific data.

Which of the 2 following organisms are
closest in relationship: Salamander,
Turtle, and Leopard. And why?
