Structural, Functional and Behavioural Adaptations
Biology · 50 practice questions
Adaptive colouration and its functions; behavioural adaptations in social animals; structural adaptations in organisms, for obtaining food, protection/defence, securing mates, regulating body temperature and conserving water.
- Describe how structures, functions and behaviour adapt organisms to their environment.
- Categorize countershading and warning colouration.
- Differentiate castes in social insects and their functions.
- Account for basking, territorial behaviour, hibernation and aestivation under unfavourable conditions.
Try a few questions
- Practice question 1
Dormancy, as a general adaptation in some organisms, specifically allows survival through
- A.a factor entirely unrelated to surviving periods of unfavourable conditions
- B.periods during which conditions are, in fact, consistently most favourable
- C.no particular period of any kind, despite being described as an adaptation
- D.periods of unfavourable environmental conditions
Show the answer
D. periods of unfavourable environmental conditions
Dormancy, as a general adaptation in some organisms, specifically allows survival through periods of unfavourable conditions.
- Practice question 2
The thin, moist skin of an amphibian specifically is an adaptation that allows it to supplement lung breathing with
- A.additional digestion of food occurring directly across the skin
- B.additional excretion of solid waste occurring directly across the skin
- C.additional gaseous exchange occurring directly across the skin
- D.a factor entirely unrelated to additional gaseous exchange across the skin
Show the answer
C. additional gaseous exchange occurring directly across the skin
The thin, moist skin of an amphibian specifically is an adaptation allowing supplementary gaseous exchange across the skin.
- Practice question 3
The hard exoskeleton of many insects, besides providing support, specifically also functions as an adaptation to
- A.increase the rate of water loss from the body significantly
- B.increase the insect's own overall body temperature directly
- C.a factor entirely unrelated to reducing water loss of any kind
- D.reduce water loss from the body
Show the answer
D. reduce water loss from the body
The hard exoskeleton of many insects, besides providing support, specifically also functions as an adaptation to reduce water loss.
