Question

page(s) 438 - 441 22.5 describe the stages of prenatal development in humans.
match the developmental events with the trimester in which they occur.
taste buds develop. heartbeat is audible. facial characteristics*(mouth, eyes, ears)begin to develop.
drag each item above to its appropriate location in the image. note that every item may not have a match, while some itemsmay have more than one match.
first trimester
embryo differentiates
second trimester
fetus grows
third trimester
fetus can survive if born

Explanation:

• First Trimester: Facial characteristics (mouth, eyes, ears) begin to develop. During this stage, the embryo is undergoing rapid differentiation, and the basic structures of the face start to form.
• Second Trimester: Heartbeat is audible. As the fetus grows in the second trimester, the development progresses to the point where the heartbeat can be detected.
• Third Trimester: Taste buds develop. In the later stages of pregnancy (third trimester), more refined developments like the formation of taste buds occur as the fetus continues to mature.

Answer:

• Facial characteristics (mouth, eyes, ears) begin to develop: First Trimester
• Heartbeat is audible: Second Trimester
• Taste buds develop: Third Trimester
