Answer:
The answer is c) The plant seeds are more likely to germinate after exposure to red light than after exposure to far-red light
Explanation:
Phytochromes are involved in the biological cycle of the plant, from germination to flowering and tubing. The red light (660 nm) activates the phytochrome, while the ultra-red or far red light (730 nm) inactivates it. In both positive photoblastic seeds (response of the seeds to light) and in the negative photoblastic seeds the red light stimulates germination, while the distant red light inhibits it.
Answer:
A woman creates new immature ova in the ovary each time she has a menstrual cycle.
Explanation:
During the menstrual cycle, hormones present in the body make the immature eggs 'mature' ones, in the ovary. About in half of the cycle, hormones make the release of the mature egg from the ovary and travels towards uterus. It can remain there for 24 hours and if not fertilized the it breaks down and released out.
