What factor makes the hawaiian islands the perfect place for plant species to diversity

Either the isolation of the islands, the variety of ecosystems found on the islands, or the nutrient rich soils.  Idk...

The nutrient-rich soils.

Explanation:

The Hawaiian Islands surfaced between 400,000 and 5 million years ago. However, the entire undersea chain has been in existence for over 60 million years! Still, in geologic terms, the Hawaiian Islands are relative newcomers to Earth. These islands are isolated in the middle of the Pacific Ocean. They were created by volcanic activity from the "hot spot" in Earth’s crust. These underwater mountains eventually surfacecreating islands. The resulting volcanic soil is rich in nutrients. As Hawaii is located in a tropical region, the climate provides warm temperatures and an ample water supply. These resources provide all the requirements to support an abundance of plant life. An unoccupied landscape offers a wide variety of empty niches. This is the perfect recipe for plant diversification.

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.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.
