The correct answer is fallopian tube.
The fallopian tube, also known as uterine tube or oviduct, carries the egg from ovary to the uterus.
The fallopian tube has finger-like projections or branches called fimbriae which reach out into the pelvic cavity and pick up an egg that has been released from the ovary.
The egg is tenderly brought into the fallopian tube where it begins to travel to the uterus.
The fallopian tube also serves as the location where fertilization of the egg by a sperm cell occurs.

Explanation:
By understanding DNA and gene expression, humans have been able to understand how genetic diseases are caused, therefore they have been able to devise gene therapy and other technologies to treat such disease. Second, the understanding has also allowed humans to devise plants that are resistant to pests and drought hence increasing crop yields.
A negative aspect of this understanding is the issue of bioterrorism. In the wrong hands, this technology can be used against society. The technology can be used to modify organisms to make them deliberately harmful to humans. Second is the issue of bioethics. This technology can be used to enhance humans and result to an ‘arms race’ between human races that can tear down the social fabric.
Explanation:
Homeostasis is the term use to describe the internal stability needed for survival of an organism, including humans and animals while equilibrium is narrow to specific mechanisms.
