diploid

Answer 43

- Fertilization (Zygote in fallopian tubes) - 2 cells (goes down fallopian tubes) - 4 cells (goes down fallopian tubes) - morula (goes down fallopian tubes, entering uterus) - Blastocyst (now in uterus and implanted) - human germ - embryo - fetus

Question 44

How is nutrients transferred between the mother and fetus?

Answer 44

the mother's blood will go around the placenta diffusing nutrients ( NOT BLOOD) to the child. These nutrients will go thru the umbilical cord and to the fetus.

Answer 57

right after the child becomes a embryo, cells make up the ecto, meso, and endoderm. This occurs when specific genes are turned on to make specific cells
