Which process results in the embryo stage of a eukaryotic life cycle?
A. Body features change during molting.
B. Meiosis produces gametes.
C. Body features change during metamorphosis.
D. A zygote divides using mitosis.

The process that results in the embryo stage of a eukaryotic life cycle is a zygote divides using mitosis (option D).

Explanation:

Embryonic development begins after fertilization - when the egg or zygote is formed - and consists of a process of successive mitosis divisions, which lead to segmentation, or formation of the multicellular embryo.

Segmentation results in the formation of structures, such as the blastocyst and gastrula, and subsequently the formation of the three embryonic laminae -ectoderm, mesoderm and endoderm- from which the organs will be formed.

The other processes -molting, meiosis and metamorphosis- occur after birth in various animal species.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
