Sasha is testing the prototype of his lever design. He is using the design to see how changing the size of a block (fulcrum) changes the height to which a stone can be raised by the lever. Sasha's prototype is shown in the picture. Note that the same stone is used in all the tests. Before Sasha can begin his experiment, he must design a table to record his data. He has already made part of the table. What kind of data should go in the bottom row of Sasha's table? A. the mass of the stone after the measurement with each block B. the masses of the fulcrum blocks used in the tests C. the procedure for how Sasha fastened the stone to the ruler using a rubber band D. the height to which the stone is raised using the different sizes of blocks the correct answer is D

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.

i know can you plzz me with this question im sorry i didt answer your question i just need hel.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
