During the rhythmic ativity of sleep, thalamocortical neuron activity neuron activity, that in turn, activity.
a) activate, inhibits
b) inhibits, activates
c) activates, activates
d) inhibits, inhibits

b) inhibits, activates

Explanation:

During the rhythmic ativity of sleep, thalamocortical neuron activity inhibits neuron activity, that in turn, activates thalamocortical activity.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

it would be heredity
