Answer:
One strand of all the isolated DNA double helices would have C-14 labeled thymidine.
Explanation:
DNA replication is a semiconservative process which means that each newly formed DNA double helix contains one parental strand and one newly formed strand.
Since the medium has thymidine labeled with C-14, all the newly formed strands formed during DNA replication would have radio-labeled thymidine.
Therefore, by the end of 20 minutes, one out of two strands on each double helix would have labeled thymidine nucleotides.

It let's more fluids flow through unlike Model A
There are living organisms that do these processes alongside one another to sustain a balanced cycle.
Really depends on what layer of crust could be a earth quake or sunami or just even a mountain forming
