Explanation:
An atom is made up of three fundamental particles:
- Protons are positively charged particles in an atom
- Electrons are negatively charged.
- Neutrons carry no charges.
In a neutral atom, the number of protons and electrons are the same and equal.
Most atoms are usually depicted this way:
ᵃₙX
where a is the mass number of the atom.
n is the atomic number
X is the symbol of the atom
The mass number is the sum of the number of protons and neutrons
Atomic number is the number of protons.
In a neutral atom, the atomic number is also the number of electrons since the atom is neutral. It has not gained or lost any additional electrons.

Answer:
Because it is the standard operational range for measuring the body temperature of a living individual.
Explanation:
When making a measuring equipment like a thermometer, you attempt to keep the reading range (Span) as small as possible so that the reading is as accurate as feasible. Because sensors are often rated in percent of span (in this example, span = 45 C–32 C = 13 degrees Celsius), One percent of 13 equals 0.13 degrees Celsius, thus if your sensor has a usual accuracy of 1%, your temperature reading is accurate to roughly 0.1 degrees Celsius.
Your precision would be 0.2 degrees Celsius if you doubled the span. The reading accuracy is now becoming unsatisfactory. Readability is another advantage of analog and mercury clinical thermometers. The markings for 0.1 deg C would be ten times closer together if a mercury thermometer had ten times the range (span). There is a limit to the device's readability.

So there's no way for us to guide you to select the correct one, and
if I want to answer this question and scoop up a few points, I have to
invent an answer from scratch.
On a speed/time graph, a VERTICAL line segment represents something
that's physically impossible.
The top of the line segment is a speed that's faster than the bottom
of the segment, but the times are both the same.
A change of speed that takes no time would correspond to infinite
acceleration. That just simply sounds wrong, and it is. Can't happen.
