TB. It is open to change.he thing about science is that a discovery may be made today and written up but by tomorrow something else is found that edifies what was found or proves it incorrect or make it obsolete. .Therefore the answer is <span>B. It is open to change</span>
Lipids serves as the fluid interface between the intracellular and extracellular environments
<span>The answer is c. Chromosomes carry the codes for hereditary traits. Chromosomes are thread-like structures made of proteins and DNA. Codes for hereditary traits are present in a molecule of DNA. Chromosomes can be found in the nucleus of each cell. Humans have 46 chromosomes in each cell (not 460) arranged in 23 pairs (not 230). Hope this helps. Let me know if you need additional help!</span>
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.
