Explanation

• The male reproductive part of a flower is called the Stamen.

It consists of two parts:

1. Anther (produces pollen grains)
2. Filament (supports the anther)

Explanation

A hydrogenation reaction occurs when vegetable oils are converted to fats.

The double bonds of vegetable oils are broken down resulting in a saturated fat i.e. ghee.

Explanation

• Sound travels fastest in diamond, with a speed of approximately 12,000 meters per second (m/s).
• This is because diamond has a very high stiffness and density, which allows sound waves to propagate quickly through the material.

The speeds of sound in different materials:

• Air: 343 m/s
• Water: 1433 m/s
• Wood: 3300-3600 m/s
• Brick: 4176 m/s
• Steel: 6100 m/s
• Diamond: 12000 m/s

Explanation

Osmosis is the movement of water molecules through a semipermeable membrane from an area of higher water concentration to lower concentration.

It is a vital process in biological systems for maintaining cell balance.

Explanation

• A habitat is the natural environment in which a living thing resides.
• Including all the living and non-living factors that affect its survival and growth.

Explanation

The SI unit of electric resistance is the ohm (Ω).

1 Ω = 1 V/A.

while

The SI unit of resistivity is an ohm-meter.

Explanation

Light year refers to speed of light expressed in miles per year

(it is about ten trillion kilometers or six trillion miles).

Light year is a unit of distance.

Light Year: the distance that light can travel in one year. 

The distance light travels in one year is known as the light year.

Explanation

Decibel (dB) is the unit used to measure sound intensity.

Which is related to the amplitude of a sound wave.

The amplitude of a sound wave determines the loudness of the sound

One decibel (0.1 bel) equals 10 times the common logarithm of the power ratio.
