Mutagens are substances that causes mutation. Mutation involves alteration of the genetic materials of an organism.
Substances such as ultra-violet radiation, x-rays, nitrous acid, viruses, fungal-infections e.t.c leads to the physical, chemical and biological alteration of genetic sequences to produce a mutant. A mutant is an organism whose genetic sequence has been altered.
Note: Pathogens are disease causing organisms. Vectors are carriers of pathogens.
M(S)=1 g
m(O)=1.5 g
M(S)=32 g/mol
M(O)=16 g/mol
n(S)=m(S)/M(S)
n(O)=m(O)/M(O)
n(S)=1/32=0.03125 mol
n(O)=1.5/16=0.09375 mol
S : O = 0.03125 : 0.09375 = 1 : 3
SO₃ - is the empirical formula
Answer:
Bacteria, Archaea and Eukarya are the three domains of life.
