Well basically rotation causes Night and Day. The earth tilts on a 23.5 degree tilt and that is also a big part of day and night. Seasons are also affected by the tilt. When the earth is tilted towards the sun, it’s summer when it’s tilted away from the sun, it’s winter
I don't know if this helps or not but you would want to know the age of the rock (absolute dating) and from there you will be able to know the age of the fossil and what caused it to die.
I’m pretty sure it’s the refractory period!!
Hope this helps!
Lipids are essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection.
