Q: why does body temperature matter?
Answer:
-reactions occur faster at higher temperatures, but enzymes have an optimal
temperature at which they work the best at temperatures too low or two high,
enzymes will lose their ability to bind to substrate and eventually denature
Q: cellular respiration
Answer:
-Organisms release the energy stored in the chemical bonds of food
molecules they eat (or the sugar they produce in photosynthesis) and use it as fuel
Energy-rich bonds are broken and ATP synthase is used to create ATP
Occurs in mitochondria
Body heat comes from energy produced from the electron transport chain that is
released
from pores

Q: endotherm (endo=inside)
Answer:
an animal that gains most of its body heat from internal metabolic
processes (cellular respiration); need more food energy and O2 at a Lowe
temperature
Q: use more oxygen at lower temperatures
Answer:
Q: ectotherm (ecto=outside)
Answer:
an animal that gains most of its body heat from external sources
as opposed to metabolic processes
Q: use less oxygen at

Q: NOT all homeotherms are endotherms (and vice versa)
Answer:
some homeothermic animals can
have a constant body temperature through behavior or a constant environment (like
reptiles
sunning on rocks or living in the tropics) rather than metabolic processes
Q: Hardy-Weinberg principle
Answer:
the principle of genetic equilibrium that relies on random mating,
a large population, no immigration or emigration, no natural or sexual selection, and
no
mutations
Q: what is the purpose of the Hardy-Weinberg principle?
Answer:
to create a model system: to observe a model population and see how frequently
genes flow

Q: five basic Hardy-Weinberg assumptions
Answer:
no mutation, random mating, no gene flow, infinite
population size, and no selection
Q: what will violations of different Hardy-Weinberg assumptions lead to?
Answer:
mechanisms of evolution: mutation, non-random mating, gene flow, genetic drift,
and natural selection
Q: antibodies
Answer:
immune system cells that attack cells with foreign antigens
