(b) formation of specific organs from Germ layers
(c) formation of three germ layers embryo from single layer embryo
(d) attachment of blastocyst to the uterine wall

Answer 1

Answer:

d) is the right answerrrr......

Answer 2

Formation of three germ layers embryo from single layer embryo

Step by step explanation:

• Gastrulation is a process in embryonic life cycle during which a blastula gets developed into three layered gastrula.
• Gastrulation takes place after their is cleavage formation in blastula.
• The three layers into which it gets developed are Ectoderm, mesoderm and ectoderm.
• These layers further get developed into different internal structures.
• Internal structures like: Ectoderm- nervous system and epidermis, mesoderm-muscle cells and connective tissues, endoderm- columnar cells found in the digestive system and many internal organs.
