Ultra violet radiation x-rays nitrous acid viruses fungal-infected peanuts all of the substances are which cause inheritable changes in genetic material. a) agents b) mutagens c) pathogens d) vectors

B) mutagens

Explanation:

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.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
