A selective permeable membrane sac filled with water and large molecules of starch is suspended in a break of distilled water then water will enter into the sack and it will swell.
This is the process of osmosis in which movement of water molecules form a solution with high concentration to lower concentration till the equilibrium attain. Starch does not pass through thee selectively permeable membrane.Water moves from outside if the cell to the inside leading to swelling of cells.
Small molecules diffuse faster than larger molecules through a membrane. The movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute.

The answer is d to the question!!!
The digestive tract is composed of layers of tissue which provide protection and aid in the digestion of food. Starting with the innermost layer, <u>these layers are:</u>
- <em>Mucosa</em>
- <em>Submucosa</em>
- <em>Muscularis</em>
- <em>Serosa</em>
<em></em>
<h3>What is the correct order the layers of the wall of the digestive tract starting with the innermost layer?</h3>
- The <u>mucosa</u> is the innermost layer of the digestive tract, and it is made up of epithelial cells that secrete digestive enzymes and absorb nutrients.
- The <u>submucosa</u> is a layer of connective tissue that provides support to the mucosa and contains small blood vessels and lymphatic vessels.
- The <u>muscularis</u> layer contains smooth muscle that helps move the contents of the digestive tract along.
- The <u>serosa</u> is the outermost layer of the digestive tract and is composed of a thin layer of connective tissue that helps protect the digestive tract from injury.
Each layer has its own <u>unique purpose</u> and contributes to the overall functioning of the digestive tract.

As temperature increases, the rate of transpiration rises as there is more evaporation.
As precipitation in the atmosphere rises, the rate of transpiration falls. Since precipitation means there is more water in the atmosphere as compared to inside the plant, less water is lost through osmosis.
