I think it’s an open source
You have to write a letter to a friend about what u learned in Science class. Here is a example
Dear Jamie, I want to tell u about some interesting things.I learned in Science class today. About
~ Cloning - the process of producing similar populations of genetically identical individuals . PUT in own words.
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’.
