Answer:
Chloroplasts
Explanation:
Chloroplasts are found in cells of leaves and green parts of the stem. They contain green pigment called chlorophyll which makes photosynthetic cells to appear green. They are sites of photosynthesis. Chlorophyll traps light energy from the sun. The energy is used to drive the manufacture of sugars from carbon dioxide and water, a process called photosynthesis.
Explanation:
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.
