Answer: gastrula, archenteron, blastospore
Explanation:
a) Gastrulation is a dramatic reorganization of the hollow blastula into a two-layered or three-layered embryo called a gastrula.
b) Invagination of cells into the blastocoel forms a tube called the archenteron.
c) The open end of the archenteron is called the blastospore..

(30%) gorilla babies die within the first few months of their lives because of inherent weakness of the infant or disease.
What is inherited disease?
Genetic factors play a role in almost all health conditions and traits, but there are some conditions in which genetic alterations play a role in almost all of the causes that cause the condition.
Genes are passed from parent to child, so are DNA changes within the gene. DNA changes can also occur spontaneously, first appearing in children of unaffected parents. This is called a new mutation, and the word mutation means change.
Therefore, (30%) gorilla babies die within the first few months of their lives because of inherent weakness of the infant or disease.
