Four groups of scientists, in different parts of the world, are dating fossils found in a rock layer of the same geologic time period. To validate the age of their fossils, the results of their tests would need to be

The options are

Complex

Identical

Inconsistent

Non-testable

The Answer is Identical

Explanation:

The groups of scientists in different parts of the world who are dating fossils found in a rock layer of the same geologic time period. The findings have to have some common characteristics which links it to being in the same geologic time period.

This however validates the fossils having to be identical to match those found in other parts of the world.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
