1. explain how the process of how the zygote makes it to the uterus to implant.

movement to the uterus: the zygote, now a blastocyst, continues its journey down the fallopian tube toward the uterus. this travel is facilitated by the cilia lining the fallopian tubes, which help move the blastocyst along.
implantation: upon reaching the uterus, the blastocyst must implant into the uterine lining (endometrium) to establish a pregnancy. this process involves the blastocyst attaching to the uterine wall and beginning to burrow into it, which is crucial for receiving nutrients and support from the mother.

Explanation:

The zygote, now a blastocyst, continues its journey down the fallopian tube (facilitated by cilia lining the tube) towards the uterus. Upon reaching the uterus, the blastocyst must implant into the uterine lining (endometrium) by attaching to the uterine wall and beginning to burrow into it. This is crucial for receiving nutrients and support from the mother.

Answer:

The zygote becomes a blastocyst. It moves down the fallopian tube (cilia - facilitated). Reaches uterus and implants (attaches and burrows into endometrium) for nutrient/support uptake from mother.
