Answer:
False.
Step-by-step explanation:
Hello!
Developmental changes are age-related changes that occur to humans trough their life. These changes are influenced by various factors such as genetic predisposition, environment, behavior, cognitive process, etc.
This means that both one's genetic blueprint and the environment were the people are growing are factors that affect the developmental changes.
Remember, the environment does not only refer to what surrounds you after birth. Before birth, the environment where the embryo develops is the intra-uterine environment, i.e. the mother's health condition, diet (if its or not balanced), consumption of determined substances (alcohol, drugs), etc... affect directly the development of the child.
I hope it helps!
