Any foreign substance that can enter an organism by diffusion can seep into an organism and replace its hard parts.
An index fossil is formed from the remains of an animal that evolved and lived for a precisely defined (and hopefully short) period of time, they are used to define and identify geologic periods. The best index fossils are wide spread (globally) and numerous (commonly found). They frequently (but not always) bottom dwelling or burrowing organisms with hard parts to their body structure because such organisms are most likely to regularly leave remains that can be fossilized.
The two parts of an ecosystem are Producers and Consumers. Producers are plants and other organisms that produce their own food. Consumers are the organisms that eat producers to survive.
Rapidly buried by sediments
I belive that is a biome, correct me if it is wrong.
Paint is a great example of a very well-mixed substance, though when it sits, it separates into its different chemical parts based on the weight of each substance.
carbon films can preserve the delicate parts of plants leaves and insects, and preserved remains can preserve entire organisms.
Most protist heterotrophs feed on bacteria, algae, other protists, and organic matter in their environment. They use various mechanisms such as phagocytosis, osmotrophy, or absorption to obtain nutrients.
Organic remains are the leftover parts of living organisms that have not completely decomposed or been fossilized. These remains can include things like bones, shells, or plant materials, and can provide important information about past life forms and ecosystems.
Yes, fossils are real. Fossils are the preserved remains or impressions of plants, animals, and other organisms that lived in the distant past. They provide valuable information about Earth's history and the evolution of life.
I think it is Fossilization too but it says it isn't. I am trying to get help a lot so I can do good on my quiz tomorrow on fossils, and this crossword puzzle saying that it starts with an "O" which I haven't seen a word that starts with that letter and has 15 letters either. Help me please?
they are original remains
There have been organisms from the beginning of time that have had hard parts on their body. This is described in creationism.
Hard parts
No , because organs are only body parts of organisms.
Regeneration is important for some organisms because it allows them to replace lost or damaged body parts, helping them survive and adapt to their environment. This ability to regrow tissues or organs can increase their chances of survival and reproduction.
Northwestern Tibet remains largely unspoiled.
The process that allows some organisms to replace parts is known as regeneration. This biological phenomenon enables certain species, such as salamanders and starfish, to regrow lost limbs, tails, or other body parts through a complex interplay of cellular signaling, growth factors, and stem cells. During regeneration, specialized cells called blastemal cells proliferate and differentiate into the necessary tissues to form the new structure. This remarkable ability varies widely among organisms, with some capable of complete regeneration while others have more limited regenerative capabilities.
