VideoQuestions-Warm vs. Cold Blooded

What does thermoregulation divide into?

• Mammals or reptiles

• Hot-blooded or cold-blooded

• Warm environments or cold environments

• Endothermic or ectothermic; homeothermic or poikilothermic

What describes an animal that makes its own heat?

• Ectothermic

• Poikilothermic

• Endothermic

• Homeothermic

Which animals are considered endothermic homeotherms?

• Dinosaurs

• Most mammals and birds

• Fish and amphibians

• Reptiles and invertebrates

What term is used for animals that get heat from the environment and let their body temperature fluctuate?

• Mesotherms

• Homeothermic

• Endothermic

• Ectothermic poikilotherms

Which animals are capable of maintaining a constant temperature by moving from cold to warmer water?

• Leatherback turtles and lamnid sharks

• Chipmunks and some bats

• Siamese cats

• Sphinx Moth

What were dinosaurs likely considered in terms of thermoregulation?

• Endothermic

• Ectothermic

• Homeothermic

• Mesotherms

What term describes animals that use a combination of internal processes and environmental factors to adjust their body temperature?

• Poikilothermic

• Ectothermic

• Mesothermic

• Endothermic

Why do ectothermic animals behave sluggishly in cooler environments?

• Because they are preparing to hibernate

• Because their muscles contract slower

• Because they are sleeping

• Because they are conserving energy for mating

What advantage do endothermic animals have over ectothermic animals?

• They can survive without food longer

• They are better at the initial attack

• They can fly without warming up their muscles

• They can always outrun ectothermic animals

Why do mammals and birds have a high cost of maintaining their body temperature?

• Because they need to eat more

• Because they need to sleep more

• Because they need to migrate

• Because they need to mate more often
