One way to get more energy out of fuels is to increase the percentage of energy used for work.

Efficiency

Explanation:

Efficiency refers to the percentage of energy that is used to perform any work. The higher the efficiency of a fuel, the higher is percentage of energy used to do work. In other words, the efficiency of a fuel can be increased by increasing the amount of energy involved in any function. This would reduce the loss of energy and heat leading to more efficient fuels.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
