Hank was studying how genetic information is passed on during sexual reproduction. He drew these pictures, each on a different flash card, to show different stages of meiosis. Later in the day, he accidentally mixed up his flash cards. Which choice below lists the stages that Hank drew in the correct order? Hint: Remember that meiosis involves two cell divisions: meiosis I and meiosis II. 1, 2, 4, 3, 5 3, 4, 1, 2, 5 3, 1, 4, 2, 5 5, 2, 4, 1, 3

An alcohol thermometer makes use of alcohol's changing in order to measure temperature. as the temperature goes up, the alcohol contained in the thermometer increases in volume, filling more of the thermometer's tube.
