✔✔Matter is anything that takes up space, by having a volume, and has mass. Matter can
6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6
exist in a solid, liquid, gaseous, or plasma state. All matter is made up of certain basic subst
6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6
ances called elements.

Explain the difference between essential and trace elements. - ans-
6 6 6 6 6 6 6 6 6
✔✔Essential elements are required for human life. Trace elements are required only in sm

all quantities.
