How do you distinguish a sample of a calcarenite fossiliferous limestone from a sample of carbonite mudstone with fossil shells?
One way to distinguish between the samples is to examine the grain size and texture: calcarenite fossiliferous limestone typically has larger grains and a coarser texture compared to the finer grains and smoother texture of carbonite mudstone with fossil shells. Additionally, conducting a chemical test such as a reaction with acid can help differentiate between the two types of rock, since limestone will fizz when it comes in contact with acid due to its calcium carbonate content.
How would you distinguish a sample of peat from a sample of mudstone that contains fossil plant fragments?
Peat is a type of organic-rich soil made up of decomposing plant material, while mudstone is a fine-grained sedimentary rock made up of clay and silt particles. To distinguish between the two, you can perform tests like observing the color and texture of the samples, conducting a chemical analysis, and looking for specific plant fossils within the samples. The presence of distinct plant fragments in the mudstone may indicate its origin from peat deposits that underwent compaction and lithification.
What do scientists use to find a date on fossiles?
Scientists use radiometric dating methods to determine the age of fossils. This technique relies on the decay of radioactive isotopes within the fossil to estimate its age. By measuring the ratio of parent and daughter isotopes in a fossil sample, researchers can calculate how long ago the organism lived.
What evidence would a scientist use to determine the absolute age of a fossil found in a sedimentary rock?
A scientist could use radiometric dating methods, such as carbon dating or potassium-argon dating, to determine the absolute age of a fossil found in a sedimentary rock. These methods rely on the decay of radioactive isotopes within the rock surrounding the fossil to calculate its age.
What are the fallacies of fossil dating?
One of the biggest fallacies of fossil dating is that they use the rock layer to help determine the age of the fossils, but the fossils are also used to help determine the age of the rock layer.

How do you distinguish an adult blood sample from a newborn infant sample?
Cord blood is a sample of blood taken from a newborn baby's umbilical cord
What does 'properties' mean in science?
A property is what characteristics something has.
What is the measuring of the ratio of unstable and stable atoms in a rock sample to determine the age of the fossil it contains?
The process is called radiometric dating. It measures the ratio of unstable isotopes to stable isotopes in a rock sample to calculate the age of the fossil within the rock. Decay of unstable isotopes, like carbon-14 or uranium-238, into stable isotopes occurs at a known rate, allowing scientists to deduce the age of the fossil.
Distinguish between a gross sample and a laboratory sample?
In geology say, a gross sample would be a representative sample of the whole rock. A lab sample would be a fraction of that, refined such that measurements are able to be made on a single mineral. for example, a piece of basalt would be a convenient field (gross) sample, from which say, mica is extracted after grinding and separation, to enable the 'date' of the basalt to be determined. Similar concepts would apply in other fields, such as biology, botany, water sampling and so on.
Does Hoechst stain dead cells in a biological sample?
Yes, Hoechst stain can be used to stain dead cells in a biological sample. It is commonly used in fluorescence microscopy to distinguish between live and dead cells based on differences in their nuclear morphology.
Distinguish between a parse and pass?
Parse is something related to computers.. It is a syntactic analsis format. pass on the other hand is a computer program for estimating sample size..
Who measures the ratio of unstable to stable atoms in a rock sample to estimate the age of the fossil it contains?
A geologist or archaeologist would use radiometric dating techniques to measure the ratio of unstable to stable atoms in a rock sample to estimate the age of the fossil it contains. This process involves analyzing the decay of radioactive isotopes present in the rock to determine its age.
How can a doctor determine the type of diabetes one may have just from a sample of blood?
A doctor can determine which type of Diabetes, Type 1 or Type 2, a person has by checking a blood sample for autoantibodies that are common in type 1 diabetes. This helps the doctor distinguish between the two types.
Where do I find someone who could tell if I have a fossil or not?
In the first instance - contact your nearest museum. They will either evaluate the sample themselves - or refer you to someone else who can give you a definitive answer.
Uses of hassium?
No practical uses have not been found, because only seven atoms have ever been made, which is not a large enough sample to distinguish any features or find any uses.
