EVALUATE Why is it necessary for engineering processes to be iterative, instead of following a fixed sequence of steps?
O a. It encourages engineers to skip steps that do not seem necessary when time and
budget are limited.
O b. It helps to ensure that the problem is well defined, criteria and constraints are met,
and the best solution is chosen.
O c. It encourages engineers to follow the most efficient path to a solution as possible.
O d. It ensures that no mistakes are made in any of the three main stages of the
engineering design process.

"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."
