Answer:
Two processes that are involved as the chick grows into the chicken are -:
- Cell growth due to taking in nutrients.
- Cell growth due to fertilization​.
Step-by-step explanation:
- Cell growth due to taking in nutrients -: Within the egg, Special temporary organs or embryonic membranes develop both to protect the embryo and to provide nutrition, breathing, and excretion for it. The yolk sac, amnion, and allantois contain these organs include the yolk sac, amnion, and allantois.
The yolk sac provides the embryo with food. The amnium provides protection by enclosing the embryo. As a respiratory organ, the allantois collects minerals from the shell and treats waste. Until the moment of hatching, these temporary organs act inside the embryo.
- Cell growth due to fertilization​ -: In the single cell produced by the union of two parental cells, the egg and sperm, the development of the chick starts in the process known as fertilization. Division of the cells stops as the egg is laid and cools. After the egg is laid, cooling the egg does not result in the embryo 's death after the egg is laid.
Hence , the correct options are A and D.
