Which can be excluded due to the absence of fossil records? (1 point)
• the body of a jellyfish
O the shell of a snail
• a dinosaur's backbone
• the shell of a crab
The answer is the body of a jellyfish.
The body of a jellyfish can be excluded due to the absence of fossil records.
To determine which of the given options can be excluded due to the absence of fossil records, we need to consider which organisms have a higher chance of leaving behind fossilized remains.
Fossils typically form when the remains of an organism are preserved over millions of years. However, not all organisms have an equal chance of fossilization. Some factors that affect fossilization include the type of organism, its body structure, and the environment it lived in.
In this case, the body of a jellyfish can be excluded due to the absence of fossil records. Jellyfish have soft and delicate bodies that are unlikely to be preserved as fossils. Their bodies are made up of mostly water and lack hard parts like bones or shells, which are more likely to be preserved in the fossil record.
On the other hand, the shell of a snail, the shell of a crab, and a dinosaur's backbone can potentially be preserved as fossils. Snails and crabs have hard exoskeletons or shells, which have a better chance of being fossilized. Similarly, dinosaurs had bones, which are often well-preserved in the fossil record.
Therefore, the option that can be excluded due to the absence of fossil records is the body of a jellyfish.
