Question

1. what are fossils?

ordinary rocks found in the dirt
preserved remains of plants and animals
parts of plants stuck in mud

1. who studies fossils?

biologists
mathematicians

Explanation:

Question 1

Fossils are defined as the preserved remains (or traces) of plants and animals from the past. The first option is incorrect as fossils are not ordinary rocks. The third option is too limited (only parts of plants in mud, but fossils can be of animals too and not just in mud). The second option matches the scientific definition.

Biologists (specifically paleontologists, a sub - field of biology) study fossils to understand past life forms. Mathematicians study math, not fossils. So the correct option is the one with Biologists.

Answer:

B. Preserved remains of plants and animals (assuming the second option is labeled B; if original labels were different, adjust, but based on content, the option "Preserved remains of plants and animals" is correct)
