Final answer:

A chick embryo will have a heartbeat by the end of the third week of incubation, which is approximately 21 days after fertilization, as this is when the heart starts beating and establishes early cardiac activity.

Step-by-step explanation:

The chick embryo you study will indeed have a heartbeat. This cardiac activity begins relatively early in the embryonic development. Specifically, the heart is the first functional organ to form and it starts beating at the end of the third week post-fertilization. Therefore, the correct answer is that the chick embryo will have a heartbeat after approximately 21 days or by the end of the third week of incubation. This early cardiac activity is crucial as it ensures that the growing tissues receive the necessary nutrients and have waste products removed through the developing circulatory system.
