Each fossil with the layer where it will be present based on are layer A-BIRDS, layer B -dinosaurs , layer C-amphibians, layer D-Corals ,layer E -trilobites.

<h3>What is the oldest fossil layer?</h3>

The Pilbara area of western Australia's Strelley Pool is home to the oldest known fossils. Stromatolites are fossilized mats of microorganisms wedged between sedimentary layers. The fossils have an age of 3.4 billion years.

<h3>How are the layers containing the fossils organized?</h3>

The Law of Superposition, which asserts that in undisturbed rock sequences, the bottom layers are earlier than the top ones, is the foundation for this theory. Because of this, certain fossil discoveries can be dated using the strata—a particular stratum of rock—in which they were discovered.

A section of DNA encodes a gene for an enzyme involved in cellular metabolism. If a mutation event occurs that results in the de
Lady_Fox [76]

Answer:

The correct answer would be C. The protein synthesized will contain many erroneous amino acids since the loss of one base will shift the reading of the encoded base sequence.

Deletion mutation that does not occur in the multiple of three bases can results in frame-shift mutation.

It changes the reading frame of nucleotide in DNA. Thus, the reading frame of codons in mRNA would also change.

Consequently, the sequence of amino acids in a polypeptide chain would change or alter. Thus, a protein would contain many erroneous amino acids.

An example of the same is shown below in the image.
