mates over a lifetime. c) a mate for a breeding season. d) several mates over one breeding season.
2.3 Describe that some animals, in particular birds and mammals, have developed special
behaviours for rearing their young
2.4 Demonstrate an understanding of why parental care can be a successful evolutionary strategy,
including: a) increased chance of survival of offspring. b) increased chance of parental genes being
passed on by the offspring.
2.7 Explain how humans can make use of conditioning when training captive animals for specific
purposes, including: a) sniffer dogs. b) police horses. c) dolphins
2.8 Investigate animal behaviour using choice chambers
2.9 Describe how some animal behaviour requires communication
2.10 Explain how animals use a variety of types of signals to communicate, including: a) sound signals.
b) chemical signals (pheromones). c) visual signals (gestures, body language, facial expression).
2.10 Explain how animals use a variety of types of signals to communicate, including: a) sound signals.
b) chemical signals (pheromones). c) visual signals (gestures, body language, facial expression).
2.6 Describe the different behaviours exhibited by animals, including: a) innate behaviour. b)
imprinting. c) habituation. d) classical conditioning. e) operant conditioning.
2.5 Explain how, within the animal kingdom, parental care may involve
risks to the parents
2.12 Demonstrate an understanding of the work of ethologists, including: a) Tinbergen, innate
behaviour in gulls. b) Lorenz, imprinting in geese. c) Fossey, social behaviour in gorillas. d) Goodall, social
behaviour in chimpanzees.
2.13 Demonstrate an understanding of how plants and animals have co-evolved, including: a) flower
