What else can I help you with?
What type of orgarnism is most likely to be fossilised?
Those that have body parts that are already mineralized. eg. shells and bones. A coral reef is a prime candidate.
The number and location of bones of many fossil vertebrates are similar to those in living vertebrates Most biologists would probably explain this fact on the basis of a the needs of the organisms?
No, b) a common ancestor.
What type of fuel forms the dead organisms acted on by temperature and pressure of the earth?
Fossil fuel forms from the dead organisms acted on by temperature and pressure of the earth over millions of years.
What important event in the animal evolution marks the beginning of the Cambrian?
Referred to as the "Cambrian explosion", most major animal groups first appeared in the fossil record beginning about 530 million years ago.
Evidence for the history of changing life forms on earth is most often found in?
The evidence for the history of changing life forms on Earth is most often found in the fossil record. Fossils are the preserved remains or traces of ancient organisms that provide important information about the evolution of life over time. The study of fossils helps scientists understand how different species have evolved and diversified throughout Earth's history.
For what animal is the most complete fossil record?
horse
For what animal is the most complete fossil record available?
horse
Do most animals and plants that once lived on Earth have left fossil evidence?
No, most animals and plants that have lived on Earth do not leave fossil evidence. Fossilization is a rare process that only occurs under specific conditions, so many organisms decompose before they can become fossils. This is why the fossil record is incomplete and biased towards certain types of organisms.
The fossil record is not complete because?
The fossil record of all species is not complete because the circumstances for fossils to occur is very rare. There must be a special type of sediment, a special type of death (not partially eaten). Therefore, not all species or mutations can be accounted for, however, there are documented fossils for most species or at least close relations
What is most likely to have a well-preserved fossil record?
Hard structures like bones or shells are more likely to be well-preserved in the fossil record compared to soft tissues. Organisms that lived in environments conducive to fossilization, such as those with frequent sedimentation or low oxygen levels, are also more likely to have well-preserved fossils.
What type of rock is a fossil?
A fossil is evidence of an organisms existence, not a type of rock. Most fossils are found in sedimentary rocks.
What fossils offer information on the activity and physiology of the creature that made them?
Probably a trace fossil; evidences of an organisms existence, without the body. Trace fossils include footprints, feces, burrow marks, and chemical signatures.
What type of orgarnism is most likely to be fossilised?
Those that have body parts that are already mineralized. eg. shells and bones. A coral reef is a prime candidate.
Do all organisms become fossil fuels?
Well its most likely everything will become fossil fuel from a human carcass,dog,cow and bugs.
Incomplete rock record most organisms do not become?
Fossilization requires specific conditions to occur, so most organisms do not become fossils. Factors such as rapid burial, lack of decomposition, and the presence of minerals are needed to preserve the remains. As a result, the fossil record is incomplete and doesn't represent the full biodiversity that has existed on Earth.
Which of the following is true about species whose evidence is preserved in the fossil record?
Most of the species have become extinct.
What does the term living fossil mean?
A living fossil generally refers to a living organism, animal or plant, whose species has been around long enough on the planet to be part of the fossil record. Most fossilized species are extinct, but there are a few which are either still in existence, or have descendents which closely resemble them.
