Why is the ability to respond to stimuli critical?

Chemistry

1. Because that shows that you're a living thing because all living things can respond to stimuli.
2. Because an example of stimuli is a virus. If you couldn't respond to it (by fighting against it) you would probably die.

Hope it helps

Answer & explanation:

The stimuli are captured by the sensory system receptors through electrical impulses, being translated by the central nervous system (CNS) into sensations and generating responses.

Thanks to the stimuli, we can react to the cold or heat on our skin, see the things and colors around us, taste and smell foods and hear and interpret sounds.

The sensory system, responding to stimuli, maintains the functioning of the five senses, in addition to controlling the immune system, the organs and the functioning of the other systems of our body.

An atom of 125Sn has a mass of 124.907785 amu. Calculate the binding energy in MeV per atom. Use the masses: mass of 1H atom = 1
Ksenya-84 [330]

Answer:

1.06×10³ MeV/atom

Explanation:

Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.

Also, atomic number of Sn = 5 0

Thus, the number of protons = 50

Mass number is the number of the entities present in the nucleus which is the equal to the sum of the number of protons and electrons.

Mass number = Number of protons + Number of neutrons

125 =  50 + Number of neutrons

Number of neutrons = 75

Mass of neutron = 1.008665 amu

Mass of proton = 1.007825 amu

Calculated mass = Number of protons*Mass of proton + Number of neutrons*Mass of neutron

Thus,  

Calculated mass = (50*1.007825 + 75*1.008665) amu = 126.041125 amu

Given mass = 124.907785 amu

<u>Mass defect = Δm = |126.041125 - 124.907785| amu = 1.13334 amu </u>

The conversion of amu to MeV is shown below as:-

1 amu = 931.5 MeV

<u>So, Energy = 1.13334*931.5 MeV/atom = 1.06×10³ MeV/atom</u>

How much work is done if an object moves 4.5 m in has 12 Newtons of force on it
Cloud [144]

The formula of work is Work (Joules)=Force (Newtons) · distance in the direction of the force (meters), therefore its just a matter of replacing factors.

Work done = 12 · 4.5= 54 joules

Compare the potential energy of two atoms chemically bonded to their potential energy when separated.
ikadub [295]

Answer:

See explanation

Explanation:

The essence of chemical bonding is in order to attain minimum energy. The minimum energy state is the most stable state of a chemical system.

As the distance of separation between atoms decreases, the potential energy of the system decreases accordingly.

An optimum distance is reached when the two atoms attain the lowest potential energy. This is designated as the bond distance of the two atoms.

Hence two atoms have lower potential energy when bonded than when separated at large distance.
