Question

Assertion (.A ) -. Colonies of yeast multiply in sugar solution. Reason (R) - Sugar is made of sucrose which provides energy for sustaining the life activities.​

Answer 1

Explanation:

assertion and reason both are true and reason is a correct explaination of the assertion

Answer 2

Both the assertion and the reason are correct and the reason is the correct explanation for the assertion.

• Whenever a yeast colony is immersed in water, it receives no nutrition.
• Sugar solution, on the other hand, is a nutritional beverage.
• As it absorbs nutrients and hence energy, the yeast grows and begins to produce buds.
• This is why yeast colonies do not grow in water but do in sugar solution.
• As a result, colonies of yeast tend to multiply in sugar solution since it provides energy for living activities.
• Thus, both the assertion and the reason are correct and the reason is the correct explanation for the assertion.
