If one cell is isolated and all the cytosine molecules are labelled with a radioactive tag and then allowed to undergo DNA replication with normal nucleotides, how much radioactive cytosine would be found in the daughter cell DNA and in the next generation’s DNA?

1. desertification

2. captive breeding

3. black rhinoceros

4. renewable resources

in any element all atoms are the same

elements in a compound are always in a constant ratio: apex

and after water is usually warmed by the sun the water temperature raises and then evaporates .
