Amy studies two plant cells in biology class. one cell measures 8ร10โ6 meter across. the other cell measures 4ร10โ5 meter across. question 1 part a amy compares the sizes of the cells using these steps: 1. divide the whole-number factors: 8รท4=2. 2. divide the powers of 10: 10โ5รท10โ6=101=10. 3. multiply the products: 2ร10=20. she concludes that the larger cell is 20 times the size of the smaller cell. which correctly describes amyโs conclusion and process? amy is correct. she divided the whole-number parts of the expressions and then the powers of 10. then she multiplied the two products to get the correct answer. amy is not correct. she should have divided 10โ6 by 10โ5 to get 10โ1. then she would have concluded that the larger cell is 2ร10โ1=0.2 times the size of the smaller cell. amy is not correct. she should have divided 4 by 8 to get 0.5 and then divided 10โ6 by 10โ5 to get 10โ1. she should have then multiplied 0.5 by 10โ1 to conclude that the larger cell is 0.05 times the size of the smaller cell. amy is not correct. she should have divided 4 by 8 to get 0.5 and then multiplied 0.5ร10 to find that the larger cell is 5 times the size of the smaller cell.
