Answer:

A major change over long periods of time is best described as macroevolution.

Explanation:

Macroevolution would be referring to evolution on a larger scale where populations speciate etc. A, B and C are various forms of speciation and microevolution would be referring to smaller changes in evolutionary patterns e.g. in adaptive or physical traits which may not be deemed 'significant' enough to be considered a speciation event.

12In an experiment, a petri dish with a colony of bacteria is exposed to cold temperatures and then warmed again.
klemol [59]
<span>Let the equation be : at^2 + bt + c = P,
where t = time (hrs),
P = population (1000's).
 When t = 1, P = 3.03.
When t = 2, P = 1.72.
When t = 3, P = 1.17.
 Substitute these into the equation to obtain these 3 simultaneous equations : a + b + c = 3.03
4a + 2b + c = 1.72
9a + 3b = c = 1.17
 
Solving gives :
a = 0.38,
b = -2.45,
c = 5.1.
 
The equation is therefore,
P = 0.38t^2 - 2.45t + 5.1
 Testing with t = 0 to 6 gives the population values as provided, so it seems to be a valid model.
 At t = 9 hrs,
P = 0.38*9^2 - 2.45*9 + 5.1
   = 13.83.</span>
