IRISSAK [1]3 years ago

DNA is the genetic composition of the cells in the human body, think of it as the coding for a computer but for cells. These carry your genetic composition (blue eyes, Brown hair, tall, short blah blah blah) and traits like smart, funny, shy.
Hope that helps.

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.
Hope this helps

Root hairs have what kind of roles in absorption and transport of water and minerals?
Leni [432]

Explanation:

Root hairs are found in the plant it is a hair-like structure present on the surface of the root tip and Root hairs have large surface area that increase the absorption rate of water and minerals.

Water is absorbed by root hair cells through the process called Osmosis and Minerals ions is  absorbed  root hairs by the process called active transport.

The function of root hair is to collect the minerals and waters present in the soil and then transfer these nutrients and water through roots to different parts of the plant.
