Behavior and Homeostasis BSCS Ch 5

What is the role of carbon dioxide in regulating breathing rate?

• It determines the acid-base balance of the blood

• It helps in generating heat internally

• It regulates the concentration of salts in the body

• It helps in maintaining electrolyte balance

What is the primary way in which animals regulate their temperature?

• By decreasing heat loss through insulation

• By relying on the external environment

• By increasing the rate of food breakdown

• By increasing heat production through exercise

What is the main difference between endotherms and ectotherms?

• Endotherms rely on the external environment to regulate their temperature

• Ectotherms generate heat internally to regulate their temperature

• Ectotherms have a wide range of behaviors to regulate their temperature

• Endotherms maintain a nearly constant temperature, while ectotherms do not

How do mammals and birds maintain relatively constant temperatures?

• By decreasing the rate of food breakdown

• By balancing heat production with heat loss

• By relying on the external environment for heat production

• By increasing heat loss through sweating and fast breathing

What is the purpose of small desert mammals living underground or being active at night?

• To maintain a nearly constant temperature

• To decrease heat loss through insulation

• To increase heat production through exercise

• To minimize the effect of hot, dry days

How do desert lizards maintain their body temperature between 36°C and 39°C?

• By increasing heat production through exercise

• By moving in and out of the sunshine and adjusting their orientation to the Sun

• By relying on the external environment for heat production

• By decreasing heat loss through insulation

What is the adaptation of marine reptiles like sea turtles for regulating salt concentrations?

• Special salt glands above their eyes that excrete excess salt

• Special salt glands in their kidneys that excrete excess salt

• Special salt glands in their beaks that excrete excess salt

• Special salt glands in their skin that excrete excess salt

How do humans restore their electrolyte balance after sweating?

• By moving to areas of lower or higher salt concentrations

• By excreting excess salt through special salt glands

• By relying on the external environment for salt regulation

• By developing sports drinks

What is the purpose of spider crabs moving to areas of lower or higher salt concentrations?

• To maintain their internal balance of salts

• To increase heat production through exercise

• To minimize the effect of hot, dry days

• To decrease heat loss through insulation

What is the unique capacity of humans in maintaining homeostasis?

• The ability to think and make choices about their behaviors

• The ability to rely on the external environment for heat production

• The ability to generate heat internally to regulate temperature

• The ability to maintain a nearly constant temperature
