Plasma has electrons, which are also located inside lightning bolts, which gives them a negative charge. Through plasma, the lightning bolt is able to travel from the sky towards the ground

age range would be the answer

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.
