Answer :

Final answer:

The fertilized egg after conception is called a zygote, and major organ formation begins in the 2nd month of pregnancy. Touch develops first in the fetus, and the embryonic period lasts from 3 to 8 weeks. The placenta is key for nutrient exchange during development.


Explanation:

Understanding Prenatal Development

The fertilized egg formed after conception is referred to as a zygote. Following this, various stages of development occur, leading to the formation of an embryo, then a fetus. Most major organs begin to form during the 2nd month of pregnancy, as this is when the embryonic stage progresses into significant organ development.

Regarding the sensory abilities of the fetus, touch is the first sense to develop. This is followed by the ability to respond to sound and later, vision. During pregnancy, the embryonic period spans from 3-8 weeks, which is a critical time for organogenesis.

One of the notable signs of learning in the womb during the fetal period is the recognition of the mother's voice, showcasing the fetus's ability to hear even before birth. The placenta plays a crucial role throughout prenatal development, as it facilitates nutrient and waste exchange between the mother and the developing fetus.
