Vinegar could usually be added to pickles because the added acid of the vinegar inhibits any sort of bacteria from entering the substance, and this would help keep them fresh for a longer period of time too.
Answer:
The answer is A.
Explanation:
During logarithmic growth phase bacteria grows exponentially doubling every x minutes (x depends on the species). In this question doubling time/generation time is every 15 minutes and log phase takes 5 hours, which equals to the 300 minutes. During 300 minutes bacteria doubles 20 times (300/15 = 20) which equals 2^20. Bacteria culture has been started with 1000 bacterial cells so it must be added to the calculation therefore right answer is: 1000 X 2^20.
After a tornado or a hurricane the local ecosystem will be very damaged, and when the wind stops blowing, or all the water is drained/dried, the ecosystem will start recovering:
- The earth will recover
- Plants will regrow.
- Animals will come back.
- The ecosystem will slowly rebuild.

The forest A which is near to the village will be saved by the local volunteers and hence suffers less damage as compared to forest B which was far away. Both the forest will go under secondary succession.
<h3>What is Ecological Succession?</h3>
Ecological succession is the process of changes in the species structure of an ecological community over time. The time scale for a succession to take place can be decades or more or less.
Succession begins with a relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable as a climax community.
The reason of succession is the cause of ecosystem change. It is the impact of established organisms upon their environments.
Succession is of two types: Primary Succession and Secondary Succession. When succession takes place on a bare rock then it is called primary succession as no species ever existed on that rock. However, when a forest catches fire the succession is secondary as species once existed on that place which were destroyed.
The time for secondary succession is less than the primary succession. The forest A which was near to the village will be saved by the local volunteers and hence it suffers less damage as compared to forest B which was far away.
