Can you guys check my answer to this? i think its c but i'm not really sure. could you ? this is the question: the mitochondrial dna sequence that is shared by two species has a steady mutation rate. scientists determine the sequences of these two species to be as follows:

species a: caggccattatg
species b: ccagcctatagg

this dna sequence has a known mutation rate, which the scientists used to calculate that the species diverged from a common ancestor 80 million years ago. using this information, how much more time do you predict will pass before these species differ by a total of eight base pairs?
a.) 160 million years
b.) 32 million years
c.) 48 million years
d.) 240 million years

How many variables are altered in a good experiment? a.1 b.0 c.2 d.3

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).

Acceleration is a direct result of a.) balanced forces b.) unbalanced forces c.) gravity d.) velocity
