I only need help on the first one. Please help me

No, it is not an example of a mutation.

Explanation:

Mutations occur in the chromosomes of the organism, in this case the fly. A mutation is a permanent alteration in the DNA of the fly. Therefore, if the fly were to have purple wings when it was born then it would be a mutation. However, in this case we dyed the wings of the fly purple. This does not alter or change the DNA in any way to cause a mutation.

Hope this helps!!

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

answer
