Answer:
The correct answer will be option-B
Explanation:
Three types of solution are formed based on the concentration of the solute which are:
1. High solute concentration- Hypertonic solution
2. Low solute concentration- Hypotonic solution
3. Equal solute concentration- Isotonic solution
When a cell contains a high amount of solute concentration and low concentration of water then it results in the generation of very high osmotic pressure.
If a cell is placed in an aquatic medium then due to high osmotic potential, the water will enter the cell which will lead to the rupture of the cell membrane. This process of rupture of the cell membrane is known as the plasmolysis.
Since the cell rupture due to the generation of very high osmotic potential, therefore, is the correct answer.
The stars that is very dim and red is called Red Dwarfs.

Answer: False
Explanation:
Conventionally pasteurized milk is not sterile it gets sterile after it is homogenized. The process of pasteurization involves sudden heating and sudden cowling of milk which does not kills all the microorganism but is intended to kill some of the bacteria and inactivates some enzyme.
Homogenization is a completely separate process which involve mechanical breakdown of fat molecules in the milk which increases the shelf life of milk by preventing the cream from rising at the top.
Hence, the given statement is False.
Answer:
<u>Option- D: </u>Is the best choice to choose from the given options.
Now, let us explain the term Cell cycle in a more comprehensive way.
<u>As the cell cycle is controlled at three checkpoints.</u>
- The integrity of the DNA is assessed at the G₁ checkpoint.
- Proper chromosome duplication is assessed at the G₂ checkpoint.
- Attachment of each kinetochore to a spindle fiber is assessed at the M checkpoint.
Explanation:
The cell cycle is controlled by three internal checkpoints that evaluate the condition of the genetic information.
- <u>The G₁ Checkpoint</u>:This stage determines whether all conditions are favorable for cell division to proceed. The cell can halt the cycle and attempt to remedy the problematic condition, or the cell can advance into G₀ (inactive) phase and await further signals when conditions improve.
- <u>The G₂ Checkpoint:</u> The most important role of the G₂ checkpoint is to ensure that all of the chromosomes have been accurately replicated without mistakes or damage.
- <u>The M Checkpoint:</u>It occurs near the end of the meta-phase stage of mitosis. it determines whether all the sister chromatids are correctly attached to the spindle micro-tubules
