Diploblastic blastopore - gastrovascular cavity
Protostome blastopore - mouth
Deuterostome blastopore - anus
Explanation:
Blastopores are structural indentations formed on the embryo during the gastrulation stage and this develops into mouth or anus depending upon the type of the embryo.
Diplolbastic (cnidarians) blastopores develop into the gastrovascular cavity in organisms like hydra
Triploblasts with three embryonic germ layers includes acoelomates, eucoelomates, and pseudocoelomates and the blastopores transform accordingly.
The blastopores of the triploblastic eucoelomates like the protosomes (mollusks, arthropods, annelids) transforms to the mouth, denoting ‘mouth first’; while that of the deuterostomes (chordates) transform to anus, denoting ‘mouth second’.
At the end of telophase 1, there are 43 pairs of chromosomes. At the end of telophase 2, there are 23 chromatids in each gamete.
Answer:
Ball-and-stick models show the bonds between atoms, but not the relative sizes of atoms. Space-filling models show the relative sizes of atoms, but not the bonds between atoms.
Answer:
the system of nomenclature in which two terms are used to denote a species of living organism, the first one indicating the genus and the second the specific epithet.
