A scientist cites fossil evidence to argue that modern whales evolved from relatively small, land-dwelling mammals. The scientist claims that a variety of fossil findings can be ordered in a sequence that demonstrates the evolutionary lineage.

Which analysis of the fossils would be most useful to support the scientist's claim?

A. width and length measurements, which should be the same for homologous bones
B. mineralization analysis, which would identify the specific minerals in each fossils
C. radiometric dating, which would show the absolute age of each fossil
D. biogeography, which should show that all the species lived in the same region.

Scientists who study evolution may want to know whether two present-day species are closely related. Evidence for evolution can be structural, genetic, or bio geographical.  Fossil skeletons of horse relatives dating from various time periods. ... of fossils and living species may tell us how modern organisms evolved. so D

Explanation:

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.
