How does the muscular sytem/muscles help with walking
pls asnwer asap

they work with the skeletal system and joints to expand and contract, making a motion.

Explanation:

muscles in your knee pull, then release. do that again and again, and you'll be walkin

You're able to walk because of your skeletal muscles

Explanation:

Muscles move body parts by contracting and then relaxing. Muscles can pull bones, but they can't push them back to the original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint.

Hope this helps :)

c. electrical charges of ionic bonds.

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.
