Labeled nucleotides were supplied to a cell culture before the cells began DNA replication. A simplified representation of the process for a short segment of DNA is shown in Figure 1. Labeled DNA bases are indicated with an asterisk (*). Which of the following best helps explain how the process represented in Figure 1 produces DNA molecules that are hybrids of the original and newly synthesized strands? (Hint: template refers to the parent strand that is used to make a copy)

Students in a class measured the mass of various living organisms. They then kept the organisms in the dark for 24 hours before remeasuring them. None of the organisms were provided with nutrients during the 24-hour period. The data are as follows. Change in mass in different organisms after 24 hours with no food Organism Starting Mass (g) Final Mass (g) Elodea (submerged aquatic plant) 15.10 14.01 Goldfish 10.10 9.84 Sea anemone 25.60 24.98 Which of the following is the best explanation for the pattern of change in mass of the organisms over time?
