Answer:
The correct answer will be option-A
Explanation:
Colchicine is the drug that prevents the assembly of the mitotic spindles which halts or stops the cell cycle.
The colchicine acts by inhibiting the microtubule polymerization thus mitotic spindles which takes place after the condensation of the chromosomes during prophase and pre-metaphase.
This acts as checkpoint which can halt the cell cycle at the phase of chromosome condensation.
Thus, option-A is the correct answer.
Answer:
I would say B) Blow over water in a bowl to produce ripples.
Answer;
-Honey contains a considerable amount of sugar (about 82% carbohydrate) and therefore when a microbe (e.g., a fungal spore or bacterium) lands on honey the process of osmosis causes water to be drawn out of the microbe thus blocking its ability to live and proliferate.
Explanation;
Antibiotics are used to kill or inhibit bacteria growth. Honey contains hydrogen peroxide, which may account for some of its antibacterial properties. It also has a high sugar content, which can help stop the growth of certain bacteria.
-Additionally, honey has a low pH level. This works to pull moisture away from bacteria, causing the bacteria to get dehydrated and die off.
