Ricardo is using polymerase chain reaction to quickly make copies of a segment of dna. ricardo needs to measure an exact amount of solution in order to place the solution in a test tube with the dna that is to be copied. which of the following tools should ricardo use to measure the solution? a. measuring cup b. micropipette c. scale d. a second test tube

How do temperature and salinity affect deepwater currents? they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water.
