Answer:
The correct answer would be the use of differential and selective growth medium.
Explanation:
The mixed colonies states of certain species can be developed on the differential and specific media relying on the morphology saw in the general media. These types of selective and differential media will allow certain microorganisms to grow only and not all the rest species present on the media.
It will help in recognizing species present in the mixed colonies present in such a growth medium. Different tests like catalase can be performed to dispose of certain choices not long before the utilization of the differential and particular media.
Thus, the correct answer would be the use of differential and selective growth medium.
The correct answer is: 6.173 seconds.
Explanation:
The formula for half life (of reaction) is:
Half-life = --- (A)
Where,
K = Rate constant = 0.54
I = Initial concentration = 0.30 m
Plug in the values in equation (A):
Half-life =
Hence, the half life is 6.173 seconds.
