A sedimentary rock containing a fern fossil was found. What does this tell about the area at the time the rock was formed
Stella [2.4K]

Answer:

D) The area was on land.

Explanation:

We can tell that this is the answer because of the process of elimination.

- It is not A or C, because there is not enough information given to us to determine whether the area was hot or cold.

- It is not B, because ferns do not grow in the ocean. (Unless it a specific type of water fern that have not heard about... but this is <u>highly unlikely</u>, so don't worry.)

- This leaves us with: D) The area was on land. This is the correct answer because ferns do grow on land, and a sedimetary rock containing a fern fossil is much more likely to be found on land than on the ocean floor.

Hope I could help!

Major cell parts function just like the structures and people who work together in a factory. Cells have strong cell walls and a cytoskeleton to keep their shape; the walls are made of fiber for protection just like a factory building has sturdy walls for support.

Where do duplicated chromosomes line up during metaphase?
Mekhanik [1.2K]
During metaphase, the cell's chromosomes align themselves in the middle of the cell through a type of cellular "tug of war." The chromosomes, which have been replicated and remain joined at a central point called the centromere, are called sister chromatids.
