12. How much current is drawn by a lamp that has a resistance of 150 ohms 1 point when a voltage of 50 volts is impressed across it?*
33 A
0.33 A
3 A
7,500 A

according to ohms law v= ir so i =50/150, =0.33

explanation:

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
