Explanation

• Carbohydrates are the body's primary source of instant energy.
• They are broken down into glucose.
• Which is absorbed into the bloodstream and transported to cells throughout the body.
• Where it is converted into energy.

Explanation

• Such as eye color, hair color, skin color, blood group and shape of nose and lips.

Explanation

• The Earth takes approximately 23 hours, 56 minutes, and 4 seconds to complete one rotation on its axis, which is called a sidereal day.
• This is the time it takes for the Earth to rotate once relative to the fixed stars.
• The extra 4 minutes is due to the Earth's slightly ellipsoidal shape and the effects of the Moon's gravitational pull.

Explanation

• The Earth rotates constantly from West to East.
• Which is why the Sun appears to rise in the East and set in the West.
• This rotation is also the reason why we experience day and night in a 24-hour cycle.

Explanation

• Sounds travel faster through solids than through both gases and liquids.
• Solids have a more rigid structure, allowing sound waves to propagate more efficiently and at a faster speed.

Here's a comparison of sound speeds in different materials:

• Solids (e.g., steel): up to 5,960 m/s (13,140 ft/s)
• Liquids (e.g., water): up to 1,482 m/s (4,862 ft/s)
• Gases (e.g., air): approximately 343 m/s (1,125 ft/s)

Explanation

• The temperature range of the clinical thermometer is 94°F to 108°F.
• A clinical thermometer is a device that measures the temperature of the body.
• A mercury bulb is located at the end of a long, narrow glass tube.
• The average body temperature is 37° C, but it can range between 35 and 42° C.
