Answer 1

Answer #1

Hypocot is the shoot organ which detects light during germination in both monocot and dicot species.
Hypocotyl is the transition region of the embryonic axis.
It grows above the ground carrying cotyledons in the direction of light. By this process the cotyledons become green and leaflike structure.
In the upper part of the hypocotyl, the light detects during expression of phototropin1 (photo1) photoreceptor.
This expression of photoreceptor enables the photropic responses and elongation of hypocotyl takes place in both monocot and dicot germination.

Hope it will helpful to you. Thank you

All the best

4. During the industrial revolution, there were two phenotypes of a particular species of moth, dark gray and light gray. Before the industrial revolution, the population of moths consisted of 1839 dark gray moths and 121 light gray moths as dark grey moths could easily blend into trees and escape detection by predators. After the industrial revolution, the population of moths consisted of 1607 light gray moths and 523 dark gray moths as light gray moths could now easily blend...
