Answer:
set distances were electrons can be sensed.
Explanation:
Energy levels are set distances from the nucleus of the atom where electrons can be sensed. Electrons are small, negatively charged particles in the atom that pass through the positive nucleus in the center. The energy levels are a little like the steps of the stairs. You may stand on one step or the other, but not between the moves. The same thing goes with electrons.

The cap-like acrosome covers the head of the sperm and releases enzymes that will help the sperm penetrate the egg.
<h3>What is acrosome?</h3>
The acrosome is a unique membrane organelle found over the anterior region of the sperm nucleus that has been largely preserved throughout evolution. This acidic vacuole includes a number of hydrolytic enzymes that, when produced, aid sperm penetration of the egg covers.
<h3>What is acrosome made of?</h3>
The acrosome is formed from the Golgi complex of the spermatid. The acrosome is made up of a protein matrix core and multiple hydrolytic and glycolytic enzymes that are essential for fertilization.
