A boy holds a ball of clay above the floor. He drops the clay ball, and it speeds up as it falls to the floor. The clay ball flattens as it hits the floor and remains flat. When the clay ball hits the floor, the clay
and the floor get a little warmer. (Assume that no energy is transferred between the clay ball and the air
or between the floor and the air.)

Glucose is a form of sugar found in the blood cells use glucose as a source of energy, but too much or too little can cause serious health issues so, the body uses the hormone insulin to regulate glucose n the blood insulin maintain glucose levels in the blood if blood glucose lovels got very high, what would you expect to see happen to insulin levels?

Two students are working together on an experiment that measures the effect of different liquid fertilizers on the thickness of plants’ stems. which is most likely to result in the greatest amount of error in their scientific experiment? a.one student measures the plant stem widths by using calipers. the other student measures the widths of the same plant stems again by using a different pair of calipers. b.one student measures the plant stem widths by using calipers. the other student types the measurements as they are taken into a computer spreadsheet. c.one student weighs liquids for the experiment by using a calibrated scale. the other student weighs liquids for the experiment by using a different calibrated scale.

There are fewer than 100 naturally occurring elements in the universe, but there are millions of different unified substances. explain how this can be true.
