Can you guess the title of my next video?

Write your guess in the comments section below.

Diabetes is a disease in which glucose or
sugar levels in our blood remain high.

Is it higher than the Statue of Liberty??

Most of our food is converted into glucose
and released into the bloodstream.

Insulin helps glucose get into the cells.

However, in some people, the insulin production is inadequate or it is not used well.

Hence, glucose stays and builds up in the blood, increasing the blood glucose level and thus, causing diabetes.

Diabetes type 1 occurs when our immune cells destroy the cells in pancreas which make insulin, resulting in less or no insulin production.

Diabetes type 2 occurs when pancreas cannot produce enough insulin or our bodies cannot use it well.

Gestational diabetes occurs in pregnant women.

Diabetes can lead to blindness, kidney failure, heart attacks, etc.

Hence, diabetic people should always maintain their blood glucose levels.

It might be because portable electronic devices like cell phones and tablets emit radio signals.

These signals can interfere with the flight
controls.

They may also disrupt the communication with the air traffic controllers on the ground.

Besides this, cellular towers are miles below the airplane.

Hence, cell phones try to emit a stronger
radio signal to detect the network.

This can increase the possibility of causing interference with the airplane electronic equipment.

Hence, portable electronic devices are told
to be either turned off or to be kept on airplane mode or flight mode.

This prevents the emission of radio signals, thus helping to keep all the onboard equipment working properly.

So that when we get bored we can pop them for timepass!!

A knuckle is a joint in the finger where two
bones come together or connect.

This joint is filled with a fluid called synovial fluid.

Synovial fluid is a viscous fluid containing
dissolved gases like oxygen and carbon dioxide.

When bones move, the synovial fluid prevents them from grinding against each other.

When we stretch or bend our finger, the space between the two bones increases.

This causes the synovial fluid to stretch,
thus creating low pressure in it.

Now, as gases are less soluble at low pressure, the dissolved gases in the synovial fluid undissolve.

Resulting in the formation of a bubble, which we hear as the pop sound.

Looks like you are searching for a treasure
hidden in a sunken ship!!

It will emit ultrasounds and help you locate
the ship!!

A music system will make ordinary sound!!

I know that the music system is the right
choice!!

Do you know how a sonar could locate the sunken ship??

Ultrasounds are sounds having very high frequencies which start from 20,000 Hertz.

So, is ultrasound used in sonar because of
its high frequency??

Due to its high frequency, an ultrasound can penetrate to a greater depth.

Thus helping us to locate the depth of the sea, sunken ships, etc.

But, I'm not able to hear the ultrasound??

It is because human beings can hear sound frequencies from 20 Hertz to 20,000 Hertz.

As ultrasounds have frequencies higher than 20,000 Hertz, we cannot hear them.
