Question 1

Period of rhythm

Answer 1

Time it takes to complete one cycle of activity. Ex. Sleep cycle is 24hr, menstruation is 30 days, coming out at high tide is 12hr

Question 2

Phase shift

Answer 2

To change the start time of a rhythm, how much the activity or rhythm as moved forward or back. Ex. Phase shift changes in school holiday as we turn off alarm clocks - wake up later and later every day

Question 3

Endogenous

Answer 3

Regulated internal with no environmental stimulus needed

Question 4

Exogenous

Answer 4

Controlled by environmental stimulus

Question 5

Free running period

Answer 5

Length of behaviour when there are no external cues. Natural period

Question 6

Zeitgeber

Answer 6

Time signal for biological clock. Ex. Phone or opening curtains. What causes the biological clock to occur

Question 7

Entrainment

Answer 7

Forces the free running period to follow an external pattern which resets the biological clock. Alarm resets the behaviour back to waking up at 6am daily in comparison to waking up later in the holiday

Question 8

Answer 11

No regular pattern

Question 12

Territory

Area defended by an animal

Question 13

Klinotaxis

Answer 13

Taxis in which the orientation depends on receptors alternately comparing the intensity of the stimulus as the body moves from side to side

Question 14

Orthokinesis

Answer 14

Orientation response in which the strength of the stimulus determines the rate of the linear movement

Question 15

Nasties

Answer 15

Non-directional growth response, with the instantaneous movement of water in regards to the stimulus intensity
