<span>Maggie's training regimen may put her at risk to develop secondary amenorrhea. While amenorrhea is the absence of menstruation, secondary amenorrhea is the absence of the menstrual cycle in females who have started menstruating (having had at least one cycle) and then stop menstruating for a period longer than three months. Secondary amenorrhea occurs in times of extreme stress or weight loss (such as anorexia). Female soldiers have experienced secondary amenorrhea when they have gone to war or have become prisoners of war. Hormone shots, extreme weight gain, birth control, and certain medications also cause the condition.</span>

Question 2 of 9

Answer:

The correct answer is option D.  Light and some other factors are necessary for chlorophyll production

Explanation:

By this experiment, it is clear that light is the major factor that helps in the production of chlorophyll in seedlings or plants. In this study, placing the seeds in the light turns 75 seedlings green which is possible by the production of the green pigment, chlorophyll only. So, it is proved that light is a key factor in the production of chlorophyll.

Besides light, there must be some other factors (mineral nutrition and chemical metabolites) that also play role in the production of chlorophyll or increase or decrease of the chlorophyll production as few seedlings did not turn green in the study.
