Answer: 2.81 x 10∧14 baterias after 16 hours.
Explanation:
Hi, first we have to find how many 20 minute intervals are in 16 hours.
If 1 hour = 60 min, 16hours = 960 minutes (16 h x 60 min / 1 h)
If we divide the 960 minutes (16 hours) by 20 minutes we obtain 48. (960/48)
There are 48 twenty minutes intervals in 16 hours.
Now we have to apply the exponential growth formula:
P (t) = Po (1 +r) ∧t
Where:
P (t) = population at time t
P (0) = initial population (1)
r = growth rate (1)
t = time (48)
Replacing with the values given:
P (t) = 1 (1 + 1) ∧48= 2.81 x 10∧14
2.81 x 10∧14 baterias after 16 hours.
The correct answer is letter C.
Bryophytes have biflagellate gametes and cuticle. The cuticle serves as the covering of the soft tissue of the plant which provides protection and prevents damages on the walls of the plants. The biflagellate gametes develop also as a form of protection as well. These plants have an aquatic ancestry because of their dependence on water for reproduction and survival.

Explanation:
Small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive movements. Much of a cell's supply of metabolic energy may be spent maintaining these processes.
