Photosynthesis takes place in leaves. leaves contain blank that allow for the exchange of gases during the process, and also with the process of blank. 1. a: lubricants b: stomata c: chlorophyll 2. a: traspiration b: transportation c: reproduction

1 ; b stomata.

2 ; a transpiration

B: stomata; A: traspiration

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.
