Question

Which can be excluded due to the absence of fossil records? (1 point)
© the body of a jellyfish
© a dinosaur's backbone
© the shell of a snail
© the shell of a crab

Answer 1

The body of a jellyfish can be excluded due to the absence of fossil records. Jellyfish have soft bodies that do not easily fossilize. In contrast, structures like a dinosaur's backbone, the shell of a snail, and the shell of a crab are all hard parts that are more likely to be preserved as fossils.

Answer 2

so which one is it?

Answer 3

The correct answer is **the body of a jellyfish**. Jellyfish lack hard parts that can fossilize well, leading to a scarcity of fossil records for them.
