How do offspring inherit their traits? a. Spiders have genes!

b. The Gene Fairy gives an offspring their genes under their pillow

c. Their parents share 1 gene each to the offspring's DNA.

d. Offspring only get their traits from one parent.

Their parents share 1 gene each to the offspring's DNA

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

it is stable as it is in group 0 which have full outer shells of electrons
