Using at least 3 steps explain how to make a wet mount slide with an Elodea plant​
Masja [62]
Step One - Obtain a clean microscope slide.

Step Two - Place a drop of liquid on the slide. This is the “wet” part of the wet mount. The liquid used depends on the type of cell being viewed:
If examining a plant cell, tap water can be used.
If examining an animal cell, physiological saline (or contact lens solution) must be used, because if plain water is used, the cell will explode from osmotic pressure. Unlike plant cells and bacteria, animal cells have no cell wall to structurally support them.

Step Three - Obtain the specimen to be used. Some introductory biology classics for viewing include:
Skin of an onion bulb: In order to view the cells, a very thin layer of skin must be obtained. Take a single layer of onion and bend it towards the shiny side. After it snaps, pull gently, and a transparent layer of skin, similar to Scotch tape, will appear.
Elodea leaf: Elodea leaves are two cell layers thick. The cells in one layer are smaller than the cells in the other, so elodea leaves can be used to better understand a microscope's depth of field.
Cheek cells: Human epithelial cells can be obtained by gently rubbing a toothpick on the inside of the mouth, and then swirling the toothpick in the physiological saline on the slide.
Pond water: Obtaining some water from a pond makes wet mount preparation a breeze, since the water and the specimens are both included.

A huge amount of water − 7 to 9 l − moves from the blood into the bowel every day, through osmosis and digestive secretions. sin
Alexus [3.1K]
The event order should be:

1. Ingesting food, the small bowel filled with food solutes and become hypertonic. It will attract water from the blood which is hypotonic
2. Food digested, some of it absorbed. The osmotic pressure inside bowel will be reduced.
3. All food is absorbed, the osmotic pressure reduced significantly makes it hypotonic. The blood attracts water as it is hypertonic. This will increase the blood volume
