Muscles perform what types of energy transformation?
a.) Kinetic to Potential
b.) Kinetic to Electrical
c.) Thermal to Radiant
d.) Chemical to Kinetic

d

Explanation:

Inside of your muscles, there are fibers that are always ready to use your body's energy currency - ATP - and convert that into motion. Since they use ATP, which is a form of chemical energy, and turn it into motion, or kinetic energy, the correct answer is d. Hope this helps!

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
