True
For Apex the answer is “True“.
Assuming that you mean not (p or q) if and only if P ~(PVQ)--> P so now construct a truth table, (just place it vertical since i cannot place it vertical through here.) P True True False False Q True False True False (PVQ) True True True False ~(PVQ) False False False True ~(PVQ)-->P True True True False if it's ~(P^Q) -->P then it's, P True True False False Q True False True False (P^Q) True False False False ~(P^Q) False True True True ~(P^Q)-->P True True False False

True
Coelom. It is partitioned by septa, which is a divider between segments of the worm.
yes it do hav a true body cayity or a coelom.
True coelom is body cavity lined by mesothelium on both sides as in chordates .
It was appeared in nematodes.Annelides had first true coelom.
The body cavity is a true coelom because it is lined by a layer of coelomic epithelium of mesodermal origin.
The coelom is the body cavity of an animal. A true coelom is a body cavity that is complete from mouth to anus with no breaks; there are animals that have pseudocoeloms - mouths and anuses but no solid connection between the two.
chordata
No, mollusks have a true coelom instead of a pseudocoelom. The coelom is a part of mollusks and annelids that is a cavity within the mesoderm that is filled with fluid.
A coelomate animal is the one which has a body cavity in which well developed organs can be accomodated.
Cockroaches do have a true coelom, because their bodies are made up of the three layers of cells. It is called a haemocoel because the body of the body cavity is filled with blood.
Yes, they do. They have true coeloms, i.e. their coeloms (body cavities) are lined with mesodermal (referring to the embryonic germ layer which forms the muscles, nervous system, and generally the "meat" of the body") cells forming its inner lining.
No. Neither Cnidarians nor Sponges have a true coelom, or space around the gut. This is reserved for triploblastic organisms, or organisms with 3 germ layers.
