HURRY In the process of photosynthesis, plants use carbon dioxide, water, and energy to form carbohydrates and oxygen Which of the following best explains how plants follow the Law of Conservation of Mass
The reaction uses energy to produce a product without energy
A gas (carbon dioxide) and a liquid (water) use energy to produce a solid (carbohydrates).
The amount of each element that begins photosynthesis equals the amount of each element that is produced
The amount of carbohydrates at the beginning of photosynthesis equals the amount of oxygen that is produced

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
