Answer:

(A) fossil is the most useful.

It serves as an index fossil. The seashell is a great index fossil because it only appears in the sandstone layer in multiple locations in the same layer of time.

Explanation:

Index fossils are fossils used to define and identify geologic periods. Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends.

PIT_PIT [208]
The correct answer should be because they want to establish a sense of time passing by and things changing over the course of time. Each new era is influenced by the previous one so the way time passes is important because as time passes by things change and the historians monitor it and record it in a chronological order.

Why is the word translation used for protein production?
Elza [17]
During translation, a ribosome reads a sequence of mRNA (messenger RNA) in groups of 3 bases called codons. The ribosome then calls for a tRNA (transfer RNA) molecule with another group of 3 bases that correspond to the codon. This group of bases is called an anticodon. The ribosome strings the anticodons together to create an amino acid chain, and then final processing occurs to create the desired protein. In a way, the ribosome is translating the language the mRNA is using into a language that the tRNA can understand, hence why translation is used.
