Semen is produced and originates from the seminal vesicle, which is located in the pelvis. The process that results in the discharge of semen is called ejaculation. Semen is also a form of genetic material. In animals, semen has been collected for cryoconservation. Cryoconservation of animal genetic resources is a practice that calls for the collection of genetic material in efforts for conservation of a particular breed.
The measure of this brightness is the luminance in candela per square metre6. 2.4.1 Luminance and Brightness We have used the terms luminance and brightness interchangeably.
The ampere per meter squared is a small unit of current density. Suppose a wire has a cross-sectional area of one millimeter squared (1 mm 2). This is 0.000001 meter squared (10 -6 m 2). If the current density in this wire is 1 A/m 2, then the wire carries 10 -6 A, or one microampere (1 ÂµA), a tiny current.
