Higher Biology Unit 2 KA5 Metabolism and Adverse Conditions

Which of the following is not an adaptation to allow an organism to survive in adverse conditions?

• torpor

• aestivation

• hibernation

• migration

Which of the following would not occur during dormancy?

• increased metabolic rate

• decreased metabolic rate

• decreased body temperature

• decreased breathing rate

Why are periods of dormancy important for some organisms?

• To allow survival during a period when the costs of normal metabolic activity would be too high.

• To allow survival during a period when the costs of normal metabolic activity would be too low.

• To allow organisms to avoid adverse conditions.

• To allow organisms to maintain a high metabolic rate when the external conditions are outwith a tolerable range.

Which of the following types of dormancy is used to survive low temperatures / wintery conditions?

• hibernation

• aestivation

• daily torpor

Which of the following types of dormancy is used to survive high temperatures / drought?

• hibernation

• aestivation

• daily torpor

Which of the following types of dormancy occurs fairly regularly in some organisms with metabolic rates?

• hibernation

• aestivation

• daily torpor

Which of the following allows an organism to avoid adverse conditions?

• aestivation

• migration

• daily torpor

• hibernation

Which of the following is true about migration?

• The cost of migration is low.

• It is purely innate.

• It is purely learned.

• It allows organisms to avoid metabolic adversity.

When organisms become dormant after the onset of adverse conditions this is known as..

• predictive dormancy

• consequential dormancy

• advance dormancy

• delayed dormancy

When organisms become dormant before the onset of adverse conditions this is known as..

• predictive dormancy

• consequential dormancy

• advance dormancy

• delayed dormancy
