in frogs, the animal and vegetal cytoplasm mixes after fertilization, forming a region that contains beta - catenin, a molecule that directs early development.
a. what is the term for this mixing/rearrangement of cytoplasm? cortical rotation
b. what is the name of the region formed by this mixing of cytoplasm? grey crescent
c. what body axis does beta - catenin instruct the developing embryo to form? dorsal - ventral

Explanation:

A. Cortical rotation is the process of cytoplasmic mixing in frog eggs after fertilization.
B. The grey crescent is the region formed by this cytoplasmic mixing, which contains important developmental signals.
C. Beta - catenin plays a role in establishing the dorsal - ventral axis in the developing frog embryo.

Answer:

A. cortical rotation
B. grey crescent
C. dorsal-ventral
