What would happen if LH levels peak a few days before estrogen levels peak?

The higher levels of estrogen may promote the midcycle LH surge, which is what urine OPKs look for. If this happens, the surge might come a couple of days earlier. This is called positive feedback. On the other hand, the higher estrogen levels my inhibit LH (this is called negative feedback) delaying the surge.

More Helpful Information: It is hard to predict. The higher levels of estrogen may promote the midcycle LH surge, which is what urine OPKs look for. If this happens, the surge might come to a couple of days earlier. This is called positive feedback. On the other hand, the higher estrogen levels my inhibit LH, delaying the surge. You will need to test for ovulation to find out.

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.
