Explain the process of evolution through isolation that results in speciation.

Isolation results in speciation through many evolutionary factors. There are four main types of isolation mechanisms: geographical, anatomical, temporal, and behavioral. Geographical isolation occurs due to physical boundaries, such as mountain ranges or rivers. Anatomical isolation occurs when species cannot physically mate or their offspring cannot survive/infertile, for their genitalia/gametes are not compatible. Temporal isolation occurs when species do not interbreed because they breed at different times. Behavioral isolation occurs when there is a difference in courtship or other behavior prevents mating. Biogeographical isolation is a mechanisms for evolution. A single species can evolve into several different species. Species evolve in order to fill a unique niche, the role an organism plays in the environment in which it lives.

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.
