Endotherms and Ectotherms Quiz

What was the main focus of the previous video tutorials?

• Genetic mutations and inheritance

• Cell division and growth

• Photosynthesis and respiration

• Enzyme function and homeostasis

What does a change in ambient temperature refer to?

• A change in the organism's metabolic rate

• A change in the temperature of the external environment

• A change in the humidity levels

• A change in the internal temperature of an organism

How do endotherms maintain a consistent internal temperature?

• By moving to different locations

• By changing their color

• Through their internal metabolism

• By absorbing heat from the environment

Which of the following is an example of an endotherm?

• Tree frog

• Australian barking gecko

• Australian bear-nosed wombat

• Desert lizard

What is a key characteristic of ectotherms?

• They maintain a constant internal temperature

• They generate heat through metabolism

• Their internal temperature depends on the external environment

• They have high metabolic rates

Which of the following is an example of an ectotherm?

• Platypus

• Kangaroo

• Koala

• Australian barking gecko

How do endotherms and ectotherms differ in their temperature regulation?

• Endotherms use homeostasis, while ectotherms rely on external temperature

• Both use homeostasis

• Endotherms rely on external temperature, while ectotherms use homeostasis

• Both rely on external temperature

What behavioral response do wombats exhibit in hot temperatures?

• Basking in the sun

• Burrowing deep underground

• Flattening their bodies

• Lifting their bodies off the ground

What physiological response do wombats exhibit to conserve energy?

• Moving to different locations

• Increasing their metabolism

• Lowering their metabolism

• Changing their color

What is vasodilation?

• Decrease in metabolic rate

• Increase in metabolic rate

• Expansion of blood vessels

• Constriction of blood vessels
