Explanation

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

There are almost 1000000 of nephrons in each kidney in the human body

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

Nephrons are the microscopic, structural, and functional units of the kidneys.

They are responsible for filtering waste products from the blood to produce urine,

This helps to regulate the body's fluid and electrolyte balance and maintain homeostasis.

Explanation

 The majority of food digestion is completed in the small intestine.

While digestion begins in the mouth and stomach, the small intestine,

With its three sections (duodenum, jejunum, and ileum),

It is where most chemical digestion and nutrient absorption occur,.

The pancreas and liver also contribute enzymes and bile to the small intestine to aid in this process. 

Explanation

The majority of nutrient absorption in the digestive system occurs in the small intestine,

Where the final stages of digestion take place.

This organ's structure, featuring villi and microvilli, creates a large surface area optimized for absorbing digested nutrients and most water into the bloodstream.

Explanation

Step 1: Find 1/10 of 120

1/10​×120=12

Step 2: Find quarter of that (i.e., 1/4 of 12)

1​/4×12=3

Explanation

1/10 = 0.1

Explanation

A quarter means 1/4​.

Now take 10% of a quarter:

So,

Final Answer:

Explanation

Mitosis is a type of cell division that results in two daughter cells, each with the same number of chromosomes as the parent cell, producing somatic cells (body cells).

It is responsible for:

• growth
• repair
• asexual reproduction in organisms.
