a. a clone will be physically identical to the original, but won’t be genetically identical

have a good day!

a chemical reaction happens

explanation:

passing a magnet thought the

mixture , because iron gets attracted to magnet .

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
