Deforestation increases precipitation. D. Tree roots improve soil water retention. Please select the best answer from the choices provided A B C D.

Tree roots improve soil water retention

Deforestation increases the risk of floods in an area tree roots improve soil water retention.

Why does deforestation result in higher flood risk?

When deforestation takes place, the top layer of soil can be dislodged – this is also known as soil erosion.

Answer:

The structural and functional units of the kidney are called nephron.

Fun Facts about Nephron:

Nephron is the structural and functional unit of the kidney.

Its primary purpose is to maintain the concentration of water and soluble chemicals such as sodium salts in the blood by filtering it, reabsorbing what is needed, and excreting the excess as urine.

The glomerulus and renal (kidney) tubule are the two primary structures in each nephron. Each human kidney contains around 1,000,000 nephrons.

The structural and functional units of the kidney are called the nephrons. Each human kidney contains 8-10 lakhs nephrons.

What do you mean by Kidney?

A Kidney may be defined as a pair of bean-shaped organs that eliminate waste and extra water from the blood and help keep chemicals balanced in the body.

Each nephron contains two structures i.e. Glomerulus and Tubules. The Glomerulus is a tough capillary through which a large amount of fluid is filtered from the blood.

Tubules are the other structure of the nephron in which the filtered fluid is converted into the urine.

Therefore, the structural and functional units of the kidney are called nephrons.
