I can conclude that the mineral that the scientist found is harder than chalcopyrite, pyrite, and orthoclase, but not harder than quartz. I can also conclude that the unknown mineral is a relatively hard mineral. Which ideas did you include in your answer? Check all that apply.

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

a plastic spoon that has a temperature of 78° f is placed into a bowl of soup that has a temperature of 84° f. which of these correctly describes what will happen?

energy as heat moves from the soup to the spoon.
