Answer:
The region where the embryoblast contacts the trophoblast is called the embryonic pole. ... Just before implantation, the cells in the embryoblast start to differentiate into two layers - the epiblast (primary ectoderm), and an internal layer of cuboidal cells called the hypoblast (or primary endoderm).

Explanation:
2 is wrong because bacteria are unicellular. 3 is wrong because they're not the same shape. lastly, 4 is wrong because both the bean plant and frog are made up of cells.
Answer:
A. Cadherins in desmosomes would no longer be anchored to intermediate filaments
Explanation:
Cadherins are Ca dependent molecules (proteins) that are involved in cell-cell adhesion (they are type of cell adhesion molecule-CAM). Cadherins are composed of: a small cytoplasmic component, a transmembrane component, and the extra-cellular part.
There are types of cadherins called desmosomal cadherins which are involved in the formation of desmosomes (structure for cell-cell adhesion) and they bind to linker proteins and keratin intermediate filaments.
