Independent Variable:
Dependent Variable:
Structure and Function of Cells and Organisms: The Affect of
Temperature on Cricket Chirping Rate
Results:
Explain in words what the data is showing. List the average Chirps per minute at
each temperature. How does temperature affect the Chirping rate of the
crickets?
Conclusion:
1. Was your hypothesis correct? (Rewrite you hypothesis and state if you
were correct or incorrect and write what did happen)
Temperature and function of aquatic organisms (category 5)
1. What is cellular respiration? Give the equation with the product and
reactants.
2. Enzymes are needed for cellular respiration and for all reactions to occur
in an organism, what are enzymes?
3. Many conditions affect an enzymes activity. How does temperature affect
an enzyme? (address low temp. and high temp.)
4. If temperature affects how an enzyme works and enzymes are needed for
respiration, how do you think temperature change affects insects like the
crickets?
5. Oxygen is needed for cellular respiration. How does oxygen get to cells of
organisms? Remember Passive transport?
6. Carbon dioxide is a waste product from cellular respiration. How does CO2
leave the cells and the organism?
7. Some organisms are warm-blooded (endothermic) like a dog and you, and
some are cold-blooded (ectothermic) like a crab. What does endothermic
and exothermic mean?
8. Are crickets endo- or ectothermic? How do you know?
9. How does temperature affect an endo and exothermic organism?
10. Organisms, like the crickets, are affected by conditions in the
environment. Some conditions are abiotic and some are biotic. What do
abiotic and biotic mean? Give an example of each. Is temperature abiotic
or biotic?
11. Organisms need to be able to adapt to environmental conditions or they
may not survive. They need to maintain homeostasis. What is
homeostasis? How does a cricket maintain homeostasis?
12. What is a feedback mechanism and how can it relate to crickets?
13. What is Natural Selection?
14. What is adaptation?
15. What is variation of a species and what causes it? How does it relate to
Natural Selection and Adaptation?
