<span>Groundwater is a water under the surface of the
Earth. It is widely used as a source of freshwater. Thanks to
its underground position, it is not as much vulnerable to pollution such as surface
water. However, some leaking of landfills, septic systems and agricultural
chemicals that can reach it deep down under the surface can cause groundwater
pollution.</span>
Answer:
Vas deferens → Male reproductive system
Fallopian tube → Female reproductive system.
Explanation:
In vertebrates, there are paired gonoducts for the movement of gametes from the gonads. Humans are no different.
1. Vas deferens is a male gonoduct that transports sperm away from the testes in preparation for ejaculation. Vas deferens collects secretion from seminal vesicle and becomes ejaculatory duct before draining in male urethra.
2. The fallopian tube is a female gonoduct that receives ova from the ovary when ovulation occurs. Fertilization occurs in the fallopian tube, and the early embryo moves from the tube to the uterine cavity.
3. Ciliated pseudostratified epithelium lines the vas deferens, while ciliated columnar epithelium lines the fallopian tube.
An agent, such as radiation or chemical substance, which causes genetic mutation.
