 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

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.
  

Explanation

A series of mitotic divisions in the zygote is called cleavage, 

This rapidly divides the single-celled zygote into a multicellular structure known as the morula,

Composed of individual blastomeres.

Unlike typical cell division, the embryo's size does not increase during cleavage

Instead, the zygote's volume is divided into smaller cells. 

Explanation

Given:

• Cost Price (CP) = Rs. 500

• Selling Price (SP) = Rs. 700

Step 1: Profit

$$\text{Profit}=SP-CP=700-500=200$$

Step 2: Profit Percentage

Profit %=Profit/CP ​×100
=200/500​×100
$$=0.4\times 100=40\%$$
