The graph illustrates the relative activity levels of three common digestive enzymes, where 0 represents no activity and 12 represents the highest level of activity. which enzyme is most active at a neutral ph of 7?

C) amylase

Explanation:

Amylase, found in saliva, is most active at a neutral pH of 7. This pH is too high for pepsin and too low for optimum trypsin activity.

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.

your body is trying to warm itself up. or more precisely, sensors in your skin send messages to your brain to generate heat to your body.
