Answer:

The correct answer is- emission spectrum

Explanation:

When energy is absorbed by an atom or molecule the electron in the atom jumps into a higher energy state and when it slowly releases energy it occupies multiple energy states this shows that an electron can have multiple transitions which leads to many wavelengths that form emission spectrum.

So the range of wavelength produced or emitted by an atom which is stimulated by energy(heat or electric current) is called an emission spectrum. So here electricity is used to excite the electron present in the gas tube containing neon and when electrons emit energy it shows red color. So the correct answer is the emission spectrum.

A woman is taking a hike and sees a rattlesnake appear on the path near her feet. She is startled and as a result, her heart rat
Elena-2011 [213]

Answer: False

Explanation:

When there is any dangerous situation or someone is frightened, then the flight and fight system of the body gets activated.

At chemical level the body releases  a series of hormones which makes a person alert of the situation. Rather, the respiratory rate, heartbeat, perspiration also increases in the body.

Adrenaline is the hormone responsible for keeping the person alive and alert at this time and to help the body run out of the situation.

The fat and sugar makes our brochi open wider which increases the heart beat and breathing.

Normally the heart beat or heart rate is controlled by the parasympathetic and  sympathetic nervous system of the body. The sympathetic nervous system controls the fight and flight part and the sympathetic nervous system controls the rest and digest part of the body.

So, it is the sympathetic nervous system which controls the heart beat of the body at the time of flight or fight, not the homeostasis.
