Answer:
True
Explanation:
The embryo stage covers from day 1 of embryonic development, which is still called zygote, until the eighth week of gestation. During this period of time, the embryo increases in size, multiplying its cells and undergoes strong cell changes. During this stage organs and the respiratory, digestive and nervous systems are developed. Due to the rapid development, this stage is a critical period in which the embryo is more vulnerable to the influence of the prenatal environment.
