Answer:
21 minutes or 0.35 hours
Explanation:
The formula for exponential population growth is

where
initial population of E.coli i.e 100
k is the rate of population growth i.e 2 as the population doubles
t is the time period i.e 20 minutes
Substituting the given values in above equation, we get -

Generation time
minutes
or 0.35 hours
Answer: A

because I used it during the quiz an I passed so, that is the correct answer.
Scientific INFERENCES are logical conclusions that are drawn from scientific observations. :-)
Answer:
The cell will swell.
Explanation:
The cells react distinctly when placed in different solutions like hypertonic, isotonic and hypotonic solutions. In the mentioned question, that is, in the fluid surrounding the cells, the concentration of salt reduces, which makes the solution hypotonic. Hypotonic solution exhibit high water potential and low solute concentration.
This makes the water move from the hypotonic solution to the inside of the cell as the osmotic movement occurs from high solvent concentration to low solvent concentration, thus, swelling of the cell takes place.
Answer:
The answer is C.
Explanation:
Due to fewer capillaries, mitochondria, myoglobin, and lower oxygen transport, type II- fast twitch muscle fibers are "fast" or quick to fatigue. With their short-term contractions, they also create greater force and strength.
