Explanation:

Learned behavior: The learned behavior is the one that the organism develops as a result of experience. Learned behavior contrasts with innate behavior, genetically programed that are performed with no previous experience. This behavior is not inherited from parents to progeny; instead, it is developed during life as a result of experience and environmental influence.  Learned behavior allows the individual organism to adapt to changes in the environment, and they modify by the different experiences.  Insight learning: Learning that the individual gains when faces a problem for the first time and behaves to resolve it.  Trial-and-error learning: Learning that the individual gains when facing a situation and trying to solve it in different alternative ways that might fail, until one of them is the correct one.  

When the animal or the organism faces a problem or a situation for the first time, with no previous knowledge or innate knowledge of how to solve it, it must deal with the situation in different ways until finding the solution or the correct way to get over it. Once the animal gets over the situation, it learns how to behave the next time.

The proton has a positive charge while the neutron has no charge they both make up the nucleus of the atom while the elections have a negative charge and surround the nucleus of the atom. the protons and electrons are used to calculate the atom's mass whereas the neutrons don't affect the mass
