Adult flatworms have symmetry. radial no bilateral none of the above

Bilateral symmetry

Explanation:

Bilateral symmetry is the symmetry in which when an organism is divided into two parts. When flatworms are cut into two halves by the central axis, then it is divided into two equal halves.

The bilateral symmetry of an organism creates two matching halves. If a line is drawn starting from the head of the organism which reaches to the tail divides the organism into two sides reflecting each other.

Hence, the correct answer is Option C

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

explanation:

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