Meat is not a good source of protein because it does not provide the body with all the essential amino acids.
a. true
b. false

False.

Meat is a good source of protein. There are nine essential amino acids which are required under special conditions like illness.

These are-  Histidine, Leucine, Isoleucine, Valine, Threonine, Methionine, Lysine, Phenylalanine and Tryptophan. They cannot be synthesized by the body and therefore need to be taken from external protein sources.

Since meat contains all the essential amino acids, therefore it is considered as a good source of protein. Hence, the given statement is false.

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
