Explanation

The atmospheric pressure at any place is measured by a Barometer.

The barometer was invented by Evangelista in 1644.

Explanation

The nephron is the structural and functional unit of the kidney.

Renal Corpuscle:

This is the initial filtering unit. 

Glomerulus:

A network of tiny blood vessels that filters blood, allowing small molecules, waste, and fluid to pass into the tubule. 

Bowman's Capsule:

A cup-shaped structure that surrounds the glomerulus and collects the filtered fluid. 

Renal Tubule:

An epithelial tube extending from the Bowman's capsule where reabsorption and secretion occur. 

How it Works 

Filtration:

Blood enters the glomerulus, where its smaller components are filtered into the Bowman's capsule.

Reabsorption:

As the filtered fluid moves through the renal tubule, essential substances (water, minerals, nutrients) are reabsorbed into the bloodstream.

Waste Concentration:

The remaining fluid, now concentrated with wastes and excess water, becomes urine.

Explanation

Geothermal, Solar, and Hydropower all come from naturally replenished sources.

These energies are renewable because they do not deplete with use and are environmentally friendly.

Renewable sources of energy include:

• Solar energy
• Wind energy
• Hydropower
• Geothermal energy
• Biomass

Explanation

After sunrise, trees perform photosynthesis, using sunlight to convert CO₂ and water into food.

During this process, oxygen is released as a byproduct into the air.
