The question is related to bilateral animals.
00:09
So let's see, bilateral symmetry.
00:13
The animals body can be divided into two identical halves in only one plane are said to have bilateral symmetry.
00:50
Now that bilateral symmetry begin from phylam platyhelmethease with an exception of adults of echinodermatum.
01:34
All other phyelums have bilateral symmetry.
01:39
So the tissue grade organization of platy hemorrhanex, other phylams, is found to be triple plastic.
02:21
That is, they have three germ layers.
02:32
The answer for the third part of question is option b, triple plastic.
02:41
Option b is our answer.
02:44
The next question is about nematodes.
02:52
Nematodes are commonly known as roundworms...
