Explanation

• The spine has 33 stacked vertebrae (small bones) that form the spinal canal. 

• The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx.

• Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused.

Additional Information "Important For exam point of view"

• The femur is the longest bone in the human body and the shortest bone is the stapes found in the middle ear. 
• A newborn child has 300 bones.
• ***
• The human skull is generally considered to consist of twenty-two bones—eight cranial bones and fourteen facial skeleton bones.
• The human hand has 27 bones

Explanation

Infrared radiation is strongly absorbed by water and by the atmosphere.

Although invisible to the eye, infrared radiation can be detected as warmth by the skin.

Nearly 50 percent of the Sun's radiant energy is emitted in the infrared region of the electromagnetic spectrum, with the rest primarily in the visible region.

Explanation

• according to some scientists, 100 Billion galaxies are there in the universe
• ***
• Hubble reveals an estimated 100 billion galaxies in the universe or so,
• but this number is likely to increase to about 200 billion 
  
• ****
• IN 2021:
• a previous measurement by the Hubble Space Telescope suggested there were 2 trillion galaxies spread across the universe. But the latest discovery counts only hundreds of billions of galaxies instead
• ***
• in 2022:
• The Hubble Deep Field, an extremely long exposure of a relatively empty part of the sky, provided evidence that there are about 125 billion (1.25×1011) galaxies in the observable universe.
• ****
• Hubble is the name of the Space Telescope named by Edwin Hubble, in the 1920s

Explanation

•  The film of the Camera is analog to the retina in the human eye 
  
• ****
• The retina is a thin membrane that covers the internal lower back of the attention.
• Like film in a camera, the retina is the light-touchy surface in which photos from the outdoor international come to a focus.
• ***
• The retina gets those photographs with thousands and thousands of microscopic photoreceptor cells called rods and cones. 
• The retina includes two regions known as the macula and the fovea. 

Explanation

Silicon is not the conductor

***
Aluminum and gold are metals so they are good conductors of electricity.

Now graphite is an allotropic form of carbon and is the only nonmetal that can conduct electricity.

Silicon is a semiconductor.

Explanation

A sudden violent shaking of the ground, typically causing great destruction, as a result of movements within the earth's crust or volcanic action.

Explanation

The seismic velocity increases gradually with the depth of the mantle as the pressure increases with depth  and therefore the density increases.
