(a) If the substance can be hammered to convert into sheets then it is metal if it is broken into pieces then it is non-metal. 
(b) Set up the circuit arrangement using bulb, battery, wire and switch. Place the object between the ends of circuit. If the bulb starts glowing then the substance is a metal otherwise it is non-metal because metals are good conductor of electricity.
Generally above methods can be used to identify metals and non-metals. But there are some exceptions also for example sodium is metal which is not malleable in fact it is brittle. Graphite, allotrope of non-metal carbon, is a good conductor of electricity.

The formation of germ-cells or sperms takes place in the testes. These are located outside the abdominal cavity in scrotum because sperm formation requires a lower temperature than the normal body temperature. We have discussed the role of the testes in the secretion of the hormone. testosterone, in the previous chapter. In addition to regulating the formation of sperms, testosterone brings about changes in appearance seen in boys at the time of puberty. The sperms formed are delivered through the vas deferens which unites with a tube coming from the urinary bladder. The urethra thus forms a common passage for both the sperms and urine. Along the path of the vas deferens, glands like the prostate and the seminal vesicles add their secretions so that the sperms are now in a fluid which makes their transport easier and this fluid also provides nutrition. The sperms are tiny bodies that consist of mainly genetic material and a long tail that helps them to move towards the female germ-cell.
