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.
There is only one measure of "evolutionary success": having more offspring. A "useful" trait gets conserved and propagated by the simple virtue of there being more next-generation individuals carrying it and particular genetic feature "encoding" it. That's all there is to it.
One can view this as genes "wishing" to create phenotypic features that would propagate them (as in "Selfish Gene"), or as competition between individuals, or groups, or populations. But those are all metaphors making it easier to understand the same underlying phenomenon: random change and environmental pressure which makes the carrier more or less successful at reproduction.
You will sometimes hear the term "evolutionary successful species" applied to one that spread out of its original niche, or "evolutionary successful adaptation" for one that spread quickly through population (like us or our lactase persistence mutation), but, again, that's the same thing.
