Answer: Hey so I do not know the answer to the first one because the question above is cut off. But for question 4 the answer is Fallopian tube.
Explanation: In the fertilization process it usually occurs in the (Fallopian tube) that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing. If you show the question to the top one I can edit this and give you the answer to that one too!
