the answer is A. A parasitic bacteria contaminated her food.

A parasitic bacteria contaminated her food.

Explanation:

Bacteria are simple prokaryotic single celled organisms which is capable of developing parasitic, mutualistic, commensalistic and predatorial relationships with other organisms.

According to the given situation, A parasitic bacteria contaminated her food. is the correct option this is because of the fact that bacteria are airborne organisms which are capable of colonizing the food we eat. When the food contaminated by bacteria is eaten by the host, it can infect as a parasite which means the bacteria will derive nourishment from the host body and disturbing the health of the host organisms.

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.

answer: c.
