D. Enzymes and substrates fit together like a lock and key.

d

Explanation:

a is wrong as enzymes function is to increase the rate of a chemical reaction.

b is wrong as enzymes are proteins that function as catalysts in living things

c is wrong as each enzyme can catalyse a single reaction as they all have an unique pattern

hope it helps...

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.

archaebacteria are found in in forest soil.

hope i spelled it right lol

hope i
