Nebular hypothesis.
Explanation:
- The first version of the nebula hypothesis was proposed by Immanuel Kant and Pierre Laplace.
- Today the hypothesis has been revised to fit into more current and update realities about how our solar system emerged.
- The hypothesis is the widely accepted explanation to the origin and evolution of the solar system.

Melatonin is a hormone being produced by small gland in the brain called pineal
gland that helps control sleep and wake cycles. It is also called the sleep
hormone because it gives signal that it’s time to sleep. People
also used this hormone to adjust the body’s internal clock. It is the hormone
that released in response to exposure to sunlight. When the sun sets and night
falls, the pineal is activated and begins to vigorously produce melatonin. The
