1. Contains their own DNA
2. Contains ribosomes that closely resemble prokaryotic cells
3. Reproduce by fission, and they are independent from cells.
Increases genetic variation, which in and of itself has extreme benefits such as protection against disease, capability to evolve, etc
Answer:
The answer is A
Explanation:
Because available energy decreases as you go up
Answer:
The answer is D.
Explanation:
The way x-rays are produced is as follows; using a vacuum environment in a tube, the cathode is heated to a degree where it releases electrons, then these electrons collide with the anode releasing energy that create the x-rays.
All of the options are correct. Although the electron most likely won't stop, it will slow down and change direction after the collision. The law of conservation of energy is also applied in this situation, meaning that the kinetic energy of the electron released by the cathode will transfer to the anode to produce the x-rays. Most of the energy after the collision is converted into heat, which is why the metal used as the anode can heat up to 2000 degrees celcius.
I hope this answer helps.
