Hello everyone.
00:02
So here our answer is a drag, sorry question is a drag and drop type question.
00:07
So this is a draggable items and we have to fill in these blanks.
00:11
So before dragging this, we have to number these draggable items in order for in order to the easy answering.
00:19
So this coelomic cavity as one foot as two heels as three mantle cavity as four mantle as five radula as six shell as seven and trochophore as eight.
00:41
Now we'll see the question.
00:45
The mollusks are the most successful invertebrate phylum after the arthropods and they occupy marine freshwater and terrestrial habitat.
00:57
So the mollusks are divided into seven classes each of which exhibits variation on the basic mollusk and body plan.
01:05
Three defining body features are the dash which secretes a protective calcareous dash.
01:12
So the one one of the most defining feature of this mollusk is the presence of the mantle.
01:20
So here we will write as five.
01:23
So the mantle is responsible for secreting a protective calcareous shell.
01:29
So here we will write here as seven.
01:33
Now in many species the muscular dash which is modified in various ways for locomotion or foot capture...
