The noble gases already have a full outer shell. The noble gases break the trend by being less reactive than the elements to their left.
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.

The four types of macromolecules in cells are nucleic acids, lipids, proteins, and carbohydrates.
In order to determine this, we will require some pieces of meat, preferably taken from the same animal and from the same area and of similar size. After the pieces of meat are obtained, they are sealed in a container with equal quantities of meat tenderizer. Then, keep the containers in different temperatures.
After fixed time intervals, say 3 hours, record the appearance and texture of the meat. Repeat this until readings for 5-6 time intervals have been obtained.
