Answer:

Six hours

Explanation:

Given that;

A microbiologist inoculates a flask of broth with 1 ml of 100 bacterial cells/ml

Also, the generation time of the species is 1 hour and there is no lag phase

i.e there is no  period where the individual bacteria are maturing, this will enhance a faster replication

So , since the generation time is 1 hour and we are being given 100 bacterial cells/ml

∴

After 1 hour = replication of the bacterial cells would have been doubled to =200 bacterial cells

2nd hour = 400 bacterial cells

3rd hour = 800 bacterial cells

4th hour = 1600 bacterial cells

5th hour = 3200 bacterial cells

6th hour = 6400 bacterial cells

∴ We can see that at the 6th hour, the culture has contained more than 6,000 cells/ml

How will wolf emigration affect a grassland ecosystem that supports rabbits, the wolf's primary prey?
svet-max [94.6K]

Wolf emigration will bring about the rabbit population increasing.

<h3>What is Emigration?</h3>

Emigration is defined as the movement of organisms away from a particular

area or habitat.

We are aware that Wolves feed on rabbits as a means of food in the

grassland ecosystem. This translates to the following below:

  • The greater the wolves the lesser the rabbit
  • The lesser the wolves, the higher the rabbit.

This therefore means that wolf emigration will bring about the rabbit

population increasing which makes option B the most appropriate choice.
