Match the layer of the earth with its best description.

1. inner core made of solid iron
2. outer core layer that includes the asthenosphere
3. lower mantle thin, rigid surface of Earth
4. upper mantle made of large plates that move
5. crust very dense liquid of iron and sulfur
6. lithosphere layer just outside of the outer core
7. asthenosphere plastic portion of the upper mantle of the earth

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.

the sphincter muscles at the end of the digestive tract is the anus.

good lesson

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).
