How does your reaction time to the voluntary action of your quadriceps in activity 2.2.3 compare with your reaction time to the simple reaction task in this project? the task in the previous lab involved hearing a sound and reacting with your foot. the task in this lab involved seeing a signal and reacting with your finger. what do reaction times tell you about how these signals are processed?

give me abc and i will get it for u.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
