The solution might be hypotonic.
When a drop of blood is added in the hypotonic solution, it may hemolyse Or bursting of cell take place, this is because the solvent comes inside the cell due to lower concentration of solute and it becomes hemolysed.
There are three types of solutions.
- Hypertonic condition of the solution occurs when the concentration of solute outside is higher than that inside the cell.
- Hypotonic condition of the solution occurs, when the concentration of solute outside is lower than that inside the cell.
- Isotonic condition of solution occurs when concentration of dissolved solute outside is equal to the concentration of solute inside the cell.

Answer:
C. Carbon
Explanation:
The central atom in an amino acid that all the groups connect to is a carbon atom.
Amino acids are monomeric units of proteins. They are bifunctional in that they have an amino group and a carboxyl group. These groups are attached to a carbon atom, α-carbon, in a molecule.
This is common to all amino-acids.
Answer: <u>Option B; 100</u>
Explanation: If the cell is placed in a solution with 75 ppm calcium ions, then the cell will die, because water will enter the cells and they can burst. 75 ppm is quite a hypotonic solution for survival of bacterial cells. Same is the case will 125 ppm, here the cells will die because of dehydration. The increased solute concentration will make the bacterial cells to loose water and this principle is used in preservation.
100 ppm will provide the most stable environment because the water movement will occur at a same rate and the processes of the cell can proceed at required rate.
Answer:
results in many diffuse wources in contrast to point sources where they are identifiable
Conduction and convection are means of transferring heat, the important difference is the medium through which the heat travels. Conduction occurs when heat is transferred through solid objects, like a bar.
