Pam is pregnant, and her baby already has all the genetic information needed to determine its sex, hair and eye color, skin color, and even some personality traits. What stage of development has her baby achieved? blastocyst
zygote
embryo
fetus

Fetus

Explanation:

A zygote, embryo, and blastocyst, are within the first few weeks for pregnancy. By weeks 7-9 the baby starts to grow arms, legs, ears, eyes, and more. And by 9 weeks, the baby's hair follicles grow, and so do the arms and legs as they grown longer. So by about week 10, you might be able to see and predict the baby's eye colour, and so forth.

Which leads up to the point that the baby is a fetus.

Hope this helps! :)

when you rub, you also apply pressure, that pressure can urge the poop to come out. i think that when your rubbing, you also might be slightly breaking it up and that can further fill the stomach.
