Options:
An electron has the same amount of energy in all orbitals.
An orbital can contain a maximum of two electrons.
An electron cloud represents all the orbitals in an atom.
An atom’s lowest energy level has only one orbital.
Answer: An electron has the same amount of energy in all orbitals
Explanation: An electron has the same amount of energy in all orbitals is the statement that is not true and all other statements are true.
In an atom, we have three subatomic particles which are protons, neutrons, and electrons. Electrons cannot have the same amount of energy in all orbitals because they revolve in orbits around the nucleus. That means that level of energy in electrons is always different in all orbitals.
Answer:
Walter Cannon's
Explanation:
Walter Cannon in his fight or flight theory notes that the human brain is designed to react as fast as possible to keep us safe by ensuring our body is prepared for action. Theresa being able to slam on her brakes after panicking conforms to the fundamentals of this theory. Also Cannon also in another theory known as the Cannon-Bard theory of emotion stated that in human beings, there is a simultaneous feeling of emotion and physiological reactions such as trembling, sweating, racing hearts.
Answer:
The Spanish-American War influenced the emergence of the United States as a world power in two key ways:
Explanation:
The first way is that it showed the military prowess of the U.S., a relatively young nation at the time (a little over 100 years old), against a much older nation, Spain, that had been a world-encompassing empire just a century earlier.
The second way is that it gave the United States possession of some of its first territories or colonies: Cuba, Puerto Rico, and the Phillippines. These made the United States an Empire, that had colonies just like the old European Empires like Britain and France.
