c. giraffes that stretch their necks more than other giraffes will have babies with longer necks.
d. natural selection acts on individual organisms.
e. adaptive traits allow individual organisms to better survive and reproduce.

c. Giraffes that stretch their necks more than other giraffes will have babies with longer necks.

Explanation:

Giraffes that stretch their necks will not have babies with longer necks. A trait only shows in next generation if it is genetically inherited i.e. the gametes carry the trait to the next generation.

When giraffes stretch their necks, they are modifying their actions in their life time which will have no effect on the gametes. Hence, this trait wont be passed to the next generation and babies will not have longer necks.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
