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 defecation reflex involves two postive feedback loops. these loops are the stretch receptors in the rectal walls and the sacral parasympathetic system. Defecation reflex empties the rectum by peristaltic movements push fecal matter from the sigmoid colon into the rectum. Then this distension of the rectal walls stimulates stretch receptors which results in defecation.
The answer of this question is False
According to Charles Darwin's theory of Evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

Explanation:
Lamarck's theory of inheritance of acquired characteristics states that the physical changes in the body parts of an organism are inherited to their off spring from generation to generation. During his study of physical appearance ( phenotype) of organism Lamarck said that the characters adopted according to the changes in environment by organism as a physical change in body are inheritable e.g giraffes long neck due to shortage of food the giraffes in order to reach to higher trees had to make their neck long so their neck length was increased and they had long necks so the new offspring when burn had long necks so on this basis he said that the physical changes are inherited. Giraffes with long neck had more chances of survival in the environment.
