match the developmental events with the trimester in which they occur. organs begin to differentiate. develops head hair and fine hair covers body. heartbeat becomes audible. drag each item above to its appropriate location in the image. note that every item may not have a match, while some items may have more than one match. first trimester embryo differentiates second trimester fetus grows third trimester fetus can survive if born

Explanation:

• Organs begin to differentiate: This occurs in the first trimester. During the first 12 weeks (first trimester), the embryo undergoes rapid development, and organ systems start to form and differentiate.
• Develops head hair and fine hair covers body: This is a second - trimester event. In the second trimester (weeks 13 - 28), the fetus grows, and features like hair (lanugo, which is the fine hair) start to develop.
