What are facts about carbon films fossils?
Carbonaceous film fossils are traces of plants or animals preserved as a thin film of carbon. All living organisms contain carbon. If they are compressed by layers of sediment fine details of the organism may be preserved.
A difference in an inherited trait of an organism that may lead to new species?
variation
What substance may seep into an organisms remains and replace it's hard parts?
Any foreign substance that can enter an organism by diffusion can seep into an organism and replace its hard parts.
How a mutation may not affect an organisms traits?
A mutation does not affect an organism trait for a reason. It is neutral which depends on the environment.
What types of evidence do scientists use to place an organism on a phylogenic tree and what does that placemnt tell you?
They use dna for sure and they may or may not use similar specification of genes
What is Carbonaceus film?
Carbonaceous film fossils are traces of plants or animals preserved as a thin film of carbon. All living organisms contain carbon. If they are compressed by layers of sediment fine details of the organism may be preserved.
What is a carbon films fossil?
It is an extremely thin coating of carbon on a rock that perseveres the delicate parts of an organism.
What was the preserved remains of ancient organisms called?
The preserved remains of animals of evidence of their existence are Fossils Fosssils that provide evidence about the past are called trace fossils.
What is a not preserved fossil called?
A not preserved fossil is often referred to as a "trace fossil." Trace fossils are geological records of biological activity, such as footprints, burrows, or bite marks, rather than the remains of the organism itself. They provide valuable insights into the behavior and movement of ancient creatures, even though the actual organisms may not have been preserved.
Molds filled with sediments sometimes produce?
Molds and casts may be produced when sediments fill molds left by decayed organisms.
Definition of a carbonaceous film fossil?

Depending on when the cancer is first detected, and depending on the size.the entire larynx may not need to be removed. Radiation, chemotherapy, or partial removal can be done in lieu of complete removal. In these cases, the voice may be preserved.
What type of asexual reproduction involves an organism starting to grow out of the parent organism and that may or may not remain attached to the parent organism?
Fragmentation is a type of asexual reproduction that involves an organism starting to grow out of the parent organism that may or may not remain attached to the parent organism.
Why do organisms need reproduction to survive?
The organism that is reproducing is not doing it so that it may live, but so that its genes may be passed on. Without reproduction a population would dwindle rapidly and lead to the extinction of an entire species.
Are preserved animal tracks index fossils?
According to the definition of "Index Fossils" the answer is no. The definition of an "Index Fossil" is - remains of an organism that lived in a particular geological age. While the track itself may indicate the age of sediment, it is not a fossil.
