Explanation:

according to your picture when humans have sexual intercourse the sperm is ejected inside the vagina from there the sperm starts to swim towards egg they both unite in the fallopian tube . The fertilized egg is known as the zygote which will then move towards the uterus, the cell division will take place approximately 24 to 36 hours after conception. through the process of mitosis the cell starts to divide. then you will get the embryo the embryo fixes it self to the wall of the uterus where it will get its nutrients and food from the mother this process is called implantation. then around 4th week the head nose and eyes ears and mouth start to form in the 5 th week legs and arms will form this when the embryo has now completely developed into a fetus.

and after water is usually warmed by the sun the water temperature raises and then evaporates .
