- Organisms can be
classified on the basis of their heat source. An organism that directly gets its heat from the sun is
referred to as a/an ___heliotherm__________________,
whereas an organism called a/an ____thigmiotherm________
obtains its heat from the substratum or surrounding environment.
what a Q10 value of 1.0 means in terms of reaction rate or metabolism.
Reaction is not temperature dependent
are designing an experiment to measure metabolic rate. Based on the
equation for cellular respiration, what are two different components that
could be measured? (Hint: you measured one in lab!)
Oxygen consumption or carbon dioxide production
why there is not a one-to-one correlation between metabolic rate and body
Must take into account the surface area
was the purpose of aerating the crayfish tanks and the respiratory
Maintain a high level of oxygen
does temperature relate to biological activity?
An increase in temperature will cause reactions to increase until a
point where enzymes are denatured.
- Organisms that are
temperature conforming are called _____ectotherms_________________
while organisms╣ whose source of heat is from chemical reactions within their
body are called _______endotherms_______________________.
