• They have one-way valves that prevent blood from flowing backwards and ensure it keeps moving towards the heart.

Explanation

We can measure our blood pressure on our own using a digital blood pressure monitor for automated readings or an instrument called a sphygmomanometer for manual readings.

A sphygmomanometer also known as a blood pressure monitor,  is a device used to measure blood pressure.

Explanation

• Paleontology is the scientific study of fossils and ancient life forms, focusing on the history of life on Earth, evolution, and extinction.

Explanation

Water has maximum density at 4-degree celsius

while 

When Water is in its Solid form (Ice) below 0 C

Explanation

Because sound is just vibrating air, space has no air to vibrate and therefore no sound in a vacuum.

Sound waves below 20 Hz are known as infrasound.

Sound waves above 20 kHz are known as ultrasound

Sound waves transmit a medium such as a gas, liquid, or solid.

• The speed of sound in air is about 343 meters per second
• The sound travels at 1,481 m/s in water 
• The speed of sound in a vacuum is zero meters per second,
