Stratosphere
The ozone layer protects life on earth by absorbing harmful ultraviolet radiation. The ozone layer is located between seventeen kilometers and thirty-five kilometers above the earth's surface in the stratosphere (2). The ozone layer is also known as the earth's shield. This layer contains high concentrations of ozone. It is interesting to note that Ozone is made up of three oxygen molecules; water consists of one hydrogen molecule and two oxygen molecules. It absorbs about ninety-seven percent of the sun's ultraviolet rays.

Answer:
Emission
Explanation:
Semen contains sperm and the secretions released by the accessory sex glands such as seminal vesicle and prostate gland. Before the ejaculation of semen, the muscles of the epididymis, ductus deferens, seminal vesicles, ejaculatory ducts, and prostate gland exhibit peristalsis. This results in the release of the secretions from the accessory glands and reproductive duct into the urethra. Since semen is present in the urethra, a small volume of semen is discharged even before ejaculation during emission.
