S phase is the DNA synthesis phase. During this portion of the cell cycle, the cell replicates its entire complement of DNA. It also forms the centrosome, which is the microtubule-organizing center that will eventually help the cell pull apart the DNA that will be divided between daughter cells.
Answer:
Waxing crescent and first quarter
Explanation:
A waxing crescent moon is when the Moon looks like crescent and the crescent increases ("waxes") in size from one day to the next. This phase is usually only seen in the west. The first quarter moon (or a half moon) is when half of the lit portion of the Moon is visible after the waxing crescent phase.
