What is more appropriate than a laboratory experiment when the problem or question being investigated
requires real-world evidence.

answer; i believe that the correct answer is(d) nondisjunction during meiosis;

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

is this a question? wassup
