They seem to be complex they are rapid and tend to spread
Explanation:
There is a LOOOONG process for this so here it is;
First things first.The animal dies. Soft parts of the animal's body, including skin and muscles, start to rot away. Scavengers may come and eat some of the remains. Before the body disappears completely, it is buried by sediment - usually mud, sand or silt. Often at this point only the bones and teeth remain. Many more layers of sediment build up on top. This puts a lot of weight and pressure onto the layers below, squashing them. Eventually, they turn into sedimentary rock. While this is happening, water seeps into the bones and teeth, turning them to stone as it leaves behind minerals. This process can take thousands or even millions of years.
I hope this answer helped. Thank you!
No, I am not preparing for a medical entrance exam
Receptor specificity Physical energy such as light, sound,
and heat is detected by specialized receptor cells in the sense
organs—eyes, ears, skin, nose, and tongue. When the action potential that
relays information about the stimulus through the nervous system to the brain. Sensory
receptors take in information from the environment, creating local electrical
currents; These currents are graded.
Khan Academy is great! Also, Alison (it's a website) has some free courses as well.
