Answer: Scientists believe that about 25 of the known elements are essential to life. Just four of these – carbon, oxygen, hydrogen, and nitrogen– make up about 96% of the human body. Six common elements that are important in living things are carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus. These large molecules make up the structures of cells and carry out many many processes essential to life.

Answer:
Orbital
Explanation:
The orbitals is the area or region outside the nucleus where an electron can most likely be found
Given what we know, we can confirm that the change in kinetic energy is a negative value, given that the <u>final value </u>will be zero.
<h3>What is kinetic energy?</h3>
- This is the energy of movement.
- As the car is in motion, it has kinetic energy.
- However, as the car slows down, it loses this energy.
- Once the car stops,<em><u> it no longer has kinetic energy. </u></em>
- Given that the change in kinetic energy is the <em><u>final value </u></em>minus the <em><u>initial</u></em>, and the final is zero, this will cause the change in kinetic energy for the car to be a negative value.
Therefore, since kinetic energy is the energy of movement, we can confirm that the change in kinetic energy for the car will be a negative value caused by the car coming to a complete stop.

A: Black
B: the black is hotter because the color black absorbs better heat and white doesnt do so much
