question 5 (1 point)
which statement describes the difference between ectothermic and endothermic animals?
question 5 options:
ectothermic animals live in cold climates, and endothermic animals live in warmer places.
ectothermic animals live in the water, and endothermic animals live on the land.
ectothermic animals have a lower body temperature than endothermic animals.
ectothermic animals have a body temperature that is the same as their environment, and endothermic animals have a constant body temperature.
question 6 (1 point)
as the temperature drops, a cold-blooded animal is likely to
question 6 options:
slow down as a response to the cooling temperature.
move around faster to raise its body temperature.
begin sweating in order to cool off.
show no response.
question 7 (1 point)
sweating is one way that warm-blooded animals
question 7 options:
prevent from getting to cold.
keep their bodies from having too much water.
release odors that can attract a mate.
generate heat loss through evaporation.

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
