he embryo gains a human appearance ____ weeks after fertilisationGroup of answer choices3 weeks5 weeks2 weeks4 weeks

The embryo gains a more human-like appearance approximately 8 weeks after fertilization, but based on the options provided, the closest answer regarding significant development would be 5 weeks.

Explanation:

During the first few weeks after fertilization (around 2-3 weeks), the embryo undergoes rapid cell division and begins to form the basic structures that will develop into various organs. By 5 weeks, the embryo starts to take on a more recognizable human shape, with the formation of limb buds, facial features beginning to develop, and the heart starting to beat.

While the question asks for when the embryo gains a human appearance, it's important to note that true human resemblance develops at about 8 weeks when more defined features are present. However, considering the provided choices, "5 weeks" reflects the point at which significant developmental stages have begun to take place.
