Anaphase is a stage of cell division, specifically during mitosis and meiosis, where sister chromatids are pulled apart to opposite poles of the cell. Generally, at the start of anaphase, the cell is still considered to be a single cell, though it is on the verge of dividing into two.
In terms of cell count, there is 1 cell undergoing anaphase. Therefore, if the question revolves around how many cells are in the anaphase stage, the answer is 1. However, if you are counting cells that are in the process of dividing but only considering the anaphase stage specifically, it is still 1 cell.
But if you're providing your response based on the options (14, 19, 41, 10), none of them correspond to the correct answer. If the context implies counting all cells in a population and assuming you see multiple cells going through cell division, please clarify or provide more details about the scenario.
