If a scientist finds fossilized remnants on a bone sample, they can conclude that the bone is likely ancient and has undergone fossilization, a process where organic material is replaced by minerals over time. This discovery may also suggest the bone belonged to a species that existed in a specific geological period, providing insights into the organism's environment and evolutionary history. Additionally, the context of the find, such as the surrounding sediment and other fossils, can help the scientist make further inferences about the ecosystem in which the organism lived.
This bone was near blood vessels or organs.

The word "mole" was introduced around 1896 by Wilhelm Ostwald who derived the term from the Latin word moles meaning a 'heap' or 'pile'.The unit mole was accepted in 1967 to provide a simple way of reporting a large number - the massive heap of atoms and molecules in a sample.
False. Radiometric dating is a common method used by scientists to determine the age of rocks. By measuring the ratio of radioactive isotopes to stable isotopes in a rock sample, scientists can calculate how long ago the rock formed.

This bone had nerve running through it.
This bone was near blood vessels or organs.
The presence of formania on a bone sample could indicate bacterial or fungal contamination. Further investigation would be needed to determine if the formania is derived from environmental sources or intrinsic to the bone itself. It is essential to rule out any potential artifacts or contamination during sample handling and processing.

Finding a foramina on a bone sample suggests that it is a passage for nerves and blood vessels to pass through, indicating a vital function in the body. The presence of foramina can help scientists identify the bone's location in the body and potentially infer information about the individual's health and lifestyle.

Yes, because each DNA is unique and and the scientist can just match the DNA up with andother DNA.
To identify the mineral sample as a carbonate, the scientist can perform an acid test. If the sample fizzes or produces bubbles when acid is added, it indicates the presence of carbonate minerals. Additionally, spectroscopic analysis can be used to detect the specific chemical composition of the mineral, confirming its classification as a carbonate.
At least two types of bacteria are contained in the natural water sample.
The forensic scientist can assume that the number of adenine molecules in the DNA sample is equal to the number of thymine molecules, as adenine always pairs with thymine in DNA. This is known as Chargaff's rule. By determining the number of thymine molecules, the scientist can indirectly infer the number of adenine molecules present in the DNA sample.
It is used every day by analytical scientist to find out the amount of substance in a sample.
