Exam 7: Animal Adaptations to the Environment

Some species of animals in cold environments lower the freezing point of water in their tissues by increasing solutes in their body fluids,especially

An advantage of homeothermy is

Immediately prior to flight in cool temperatures,some insects

The regulation of body temperature by internal metabolism is called ectothermy.

In marine mammals,lipids are typically deposited as a layer of fat just below the skin,referred to as ________.

Which of the following would have the most surface area assuming the same volume?

In which of the following is countercurrent heat exchange not known to occur?

The respiration rate of homeotherms is proportional to

Daily torpor is more likely to be used by large mammals than small mammals to conserve energy when inactive.

Birds and reptiles have a ________,which is a common receptacle for the digestive,urinary,and reproductive tracts that reabsorbs water back into the body.

Which of the following is the concept associated with an animal shivering in a cold environment to stay warm?

Which of the following animals has the highest mass specific oxygen consumption?

________ is the maintenance by an animal of a relatively constant internal environment in a varying external environment.

Some aquatic poikilotherms (e.g.,sharks)are able to maintain a higher internal body temperature than the surrounding water.

Aquatic organisms that have a lower salt concentration in their bodies than the surrounding water are considered ________.

Several amphibian species survive the winter using antifreeze chemicals by the process of

Freshwater aquatic organisms are faced with the problem of preventing excessive uptake or retention of water.

Thermal ________ is the ability of an organism to transmit heat.

According to Bergmann's rule,as global temperature increases,

As the surface area of a body increases,its volume increases at the same rate.
