The property of all ionic compounds that makes chalk particularly useful for writing on a chalkboard is : Hardness and Brittleness
Those properties make chalk leaves residues on the board every time friction happen between the chalk and the board
hope this helps<span />
Answer:
The correct answer would be - the cell will get water and expand.
Explanation:
If a cell with a higher salt concentration is placed ins a low salt concentration solution then the water will move through the cell membrane into the cell and the cell will swell or expand.
Water always moves from a low solute concentration to a high concentration area, therefore, if the cell has more salt concentration than outside the cell water move inside the cell which leads to an increase in the water concentration inside the cell and expands its size.
The creation of DNA fragments with ends that can join with other DNA is achieved by the use of restrictive enzyme analysis.
<h3>What are restriction enzymes?</h3>
They are enzymes utilized in genetic engineering or gene recombination technology to cut DNA at some specific points in other to have sticky ends.
The sticky ends DNAs are able to join with other DNAs using these ends. Another enzyme (Ligase) is utilized to join the DNA back once the desired DNA has been inculcated.

This indicated that Photosynthesis was occurring.
Photosynthesis- Green plants employ a process called photosynthesis to produce their own sustenance. Life on Earth depends on photosynthesis. Without it, there wouldn't be any green vegetation, and there wouldn't be any creatures either. Interactive. Sunlight, <u>chlorophyll</u>, water, and carbon dioxide gas are necessary for photosynthesis.
Chlorophyll- Chlorophyll is a pigment found in certain living creatures and all green plants. It is necessary for the process of photosynthesis, which turns light energy into chemical energy. The pigment chlorophyll is what gives plants their green color.
Pigment- A chemical that may be found in animal or plant tissue and gives off a distinctive color, such hemoglobin in red blood or chlorophyll in green plants.
