Me with these me no 19 what is homeostasis? what do unicellular organisms do to maintains homeostasis?

Homeostasis is the regulation of body temperature, ph, salt, water, pretty much balance in body

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.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface
