Answer:
15 years
Explanation:
Compound growth
Equation:
20000 x 1.05 to the power of how ever many years needed
20000 x 1.05 to the power of 15 takes it just over, with 41578 people alongside decimals.
Therefore, it is 15 years.
It can be explained by its surface tension.

I found the full exercise on the internet and it ends like this:
"<span>These genes are 30 cM apart on the third chromosome. Explain how this ratio arose." Attached is an image of the cross mentioned above.
Crossing over in the female contributed to the possible existing allele combination |e-ca| that did not exist in the parents genotypes. With this new allele combination, the new possibilities are |</span>♀e-ca/♂e-ca+|, |♀e-ca/♂e+-ca|, |♀e+-ca+/♂e-ca+|, and |♀e+-ca+/<span>♂</span>e+-ca|, leading to the respectively phenotypes ebony, claret, wild, wild. These results correspond to the obtained phenotype ratio.
Closed-ended questions<span> are those which can be answered by a simple "yes" or "no," while </span>open-ended questions<span> are those which require more thought and more than a simple one-word answer.</span>
