Answer:
I believe the scientific property referes to the composition, on an atomic level, of an element or compound. It's property(ies) are what constitutes the element in an isolated state, but also how it reacts to changes in environment: (temperature, humidity, etc..); but also how it reacts to other elements. What changes occur and if it has the potential to change it's molecular "structure".
The correct answer is the letter C. acids.
An acid contains hydrogen that has the capability of donating proton (+) in a solution. So when an acid is dissolve in a solution, it releases hydogen ions.
At first it will be filled with weeds and insects. In about 5 years, a wider variety of plants will be growing there and larger animals will live there. They are there because of the food and shelter. Then in 100 years, there would be more soil (because of decomposing dead organisms). WIth more soil, bigger plants could grow and larger animals could live.
Answer:
RBC burst when placed in pure water , Ans C -The water rushes into the cell. Cell swells and burst.
Explanation:
This can be understand by understanding OSMOSIS
Movement of water molecule from its higher concentration to its lower concentration through a semipermeable membrane is called OSMOSIS.
If cell is placed in any solution in which solute concentration is higher than inside the cell (HYPERTONIC SOLUTION), means water content in cell is higher then outside environment. Then the water molecule will flow from cell to the outer medium. Water molecule movement continues till concentration of solutes reaches same both in cell as well as in medium.
IF cell is placed in any solution having solute concentration lower than inside the cell. In this solution water content will be higher and solute concentration will be low (HYPOTONIC SOLUTION). Water movement will be inside the cell from the outer environment.<u><em> As the result Cell swells and ultimately burst because of excess water content.</em></u>
IF cell is placed in ISOTONIC SOLUTION, where concentration is same both in cell and outer environment, No movement of water molecules takes place.
