Question 24 : The answer is D. Delta Waves, because Delta waves are recorded in an EEG which is associated with a deep sleep state 3 of NREM (Non Rapid Eye Movement) sleep.

Human sleep is described in a succession of five recurring stages – four Non – REM (Rapid Eye Movement) and the REM stage. The period of non- REM Stage (stages 1-4) lasts from 90 to 120 minutes in younger adults.

Question 26 : The answer is D. Synapses. Compared with environmentally impoverished rats, those rats housed in enriched environments experienced a dramatic increase in the number of their synapses which showed greater sensory, cognitive and motor stimulation. Enriching the housing conditions showed to have an alter in the behaviour, and hormonal levels among the rodents.

Question 27 : The answer is C. Dizygotic, because fraternal twins are non – identical who come from separate eggs. They develop in the uterus separately.

Question 28 : The answer is A. Temperament. The two children are different individuals with different personalities and hence they differ in temperament. Sleep patterns are dependant on the temperament of the individuals. Some may be hyper - active and have unpredictable sleep pattern and others may be much relaxed and have predictable sleep patterns.

Question 29 : The answer is B. Interaction. Because the interaction between nature and nurture evokes responses based on patterns which are predictable to some extent.
