William is conducting an experiment to see whether objects float or sink in water depending on their density. He makes certain that each object he tests is the same shape and volume. He also uses the same amount of water in each trial. Which of these are constants in William's experiment?

answer: i say it foxes

explanation:

you need to give us the answer options to for me to offical decide.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

the answer would be d : p

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
