Growth and development in organisms can result when there is an increase in a. the number of cells. b. the sizes of cells. c. the quantity of cellular products. d. all of these

i would say D because its like adaptaion and it would help the animal to survive

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.
