Question

answer the following questions about the blastulas drawn below. which embryo (1 or 2) is a frog embryo? which letter (a, b, c, or d) points to the animal pole? which letter (a, b, c, or d) points to the vegetal pole? which letter (a, b, c, or d) points to the blastocoel? which letter (a, b, c, or d) points to a blastomere?

Explanation:

In frog embryos, the yolk - rich vegetal pole is at the bottom and the animal pole at the top. The blastocoel is the fluid - filled cavity. Blastomeres are the individual cells that make up the embryo. By comparing with the characteristics of frog embryos and the labeled parts in the diagrams, we can identify the correct answers.
