Not all of those offspring are likely to live to adulthood, whereas the parent penguin can pay attention to the one chick it has so it is more likely to live to adulthood
Answer : True
Enrichment cultures are used to increase a small number of desired organisms
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’.
