Answer:

Some fossils, known as index fossils, help geologists balance rock layers. A fossil must be broadly dispersed to be a valuable index fossil and indicate a form of organism that has lived for a short time. Index fossils are valuable when the relative ages of the rock layers are told.

1) Index fossils are of organisms that lived over a wide area. They lived for a fairly short period of time. An index fossil allows a scientist to determine the age of the rock it is in.

2) Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.

What role does iodine play within the thyroid?

lesantik [10]

Iodine it is an element that is required for the thyroid gland to produce thyroid hormones.
The body does not produce iodine on its own so it needs to come from dietary sources like eggs, prunes bananas, shrimp, cod, etc or you can take supplements of iodine.
When you consume iodine it quickly absorbed and enters into your bloodstream and thenyour thyroid that has tiny cells that capture the circulating iodine and takes in and oxidizes it so it can begin to be used to create (T3) and (T4 which are thyroid hormones.
