The correct answer is geographic isolation.

Geographic isolation refers to a term, which signifies towards a population of plants, animals, or other species, which are distinguished from exchanging genetic substance with other organisms of the same species. Usually, geographic isolation is the outcome of a coincidence or an accident.

It is considered that geographic isolation is a usual way for the procedure of speciation to start: mountains rise, rivers change course, organisms migrate, continents drift, and what was once a spontaneous population is differentiated into two or more smaller populations.

Geographic isolation refers to the distinction of two populations of the similar species or breeding group by a physical barrier, like a body of water or a mountain. Geographic isolation may eventually result in the populations becoming distinct species by adaptive radiation.

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.
