Most of the fossils we find were buried in flood sediments. Thus, rapid burial (preferably in an anoxic environment) aids in fossilization. Most of the fossils that ever existed were subsequently eroded away and obliterated by the same river systems where they were created. A second requirement, therefore, tends to be climate change, or some environmental disturbance (such as an earthquake or volcanic eruption) that changes the course of a river system, or gently uplifts a mountain range.
Some fossils, especially insects, are encased in amber. These are exquisitely well preserved, but it requires millenia for tree sap to harden into stone.
Second, for us to find the fossils, they must again erode close to the surface where fossil hunters can stumble across them and recognize them for what they are. Many fossils have been destroyed by people who did not recognize these strange things eroding out of the earth had any value.
There are three types of fossils. There are impressions, such as footprints or body parts molded in clay which subsequently hardened into stone. There is infilling, where calcium carbonate or some other substance fills in the spaces left by decaying organic matter. Both of these types of fossils can be created quite quickly. The last, mineralization, is the replacement of organic material with inorganic material. This replacement occurs over many thousands of years. It is an extremely slow process.
all three prerequisites
Not all organisms are preserved as fossils because the conditions required for fossilization are rare. Factors such as rapid burial, absence of oxygen, and the presence of minerals must align to preserve an organism as a fossil. Additionally, the soft tissues of organisms often decay before they can be fossilized.
The organism that Jason is studying most likely belongs to the Animalia kingdom. Organisms in this kingdom are heterotrophic, meaning they must consume other organisms for energy. This distinguishes them from plants, which produce their own energy through photosynthesis, and fungi, which absorb nutrients from decomposing matter.
The prerequisites for natural selection include variation within a population, heritability of traits, and differential survival and reproduction. Individuals must exhibit differences in traits that can be passed on to the next generation, and those traits must affect their ability to survive and reproduce in a given environment. This process leads to the gradual adaptation of populations over time as advantageous traits become more common.
An organism that eats other organisms is called a consumer.
It must die.

It depends on the organisms and their habitats. Most of the time, yes, organisms must compete, as this space also contains items necessary for survival such as food and water.
It depends on the organism. Most likely 6.5-7.5

Some schools will teach you the general stuff concurrently, and require no prerequisites, while other schools will ask that you've taken certain general college courses first.
The functional prerequisites that a society must satisfy if it is to survive include the following:AdaptionGoal AttainmentIntegrationPattern Maintenance
Heterotrophs are organisms that cannot produce their own food and must obtain nutrients by consuming other organisms. They rely on external sources of organic carbon for growth and energy production. Examples of heterotrophs include animals, fungi, and most bacteria.
Veterinary assisting is an entry-level position and most assistants are trained on the job. You do not earn a degree in veterinary assisting.
