Answer:
D. Nuclear fusion begins under high pressure.
Explanation:
A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.
Some of the examples of stars are;
- Sun (closest to the Earth)
Stars are typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He). The chronological order in which the formation of a star occur are;
1. Gravity pulls gas and dust together to form dense cores.
2. A protostar forms as mass increases.
3. Nuclear fusion begins under high pressure.
Hence, the final event that occurs when a star is forming is that nuclear fusion begins under high pressure.
We would over populate the eart leading to no water or no food, we would eventually go into a fallout and have nuculer war and then everything is gonna go to sh and we are going to have to repopulate

Explanation:
The endocrine system is a complex of glands that secrete <u>hormones</u> as a chemical messenger. These hormones carry information and instructions throughout the bloodstream from one part of the body to another. These hormones control many body functions such as respiration, sensory perception, metabolisms, growth, reproduction, the mood among others.
On the other hand, the nervous system is made up of neurons that communicate with each other to extend a message (from our own body or the outside) to the brain, for analysis and further decision of what to do with that information. A group of neurons, sensory neurons, respond to several stimuli such as touch, light, and sound to let the brain know about the surrounding environment. Another group of neurons, motor neurons, work inside the body and carry signals to active muscle or glands.
