Answer; Radiometric dating
Explanation:How do scientists determine the ages of the rock layers?
The age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample. Radioactive isotopes break down in a predictable amount of time, enabling geologists to determine the age of a sample using equipment like this thermal ionization mass spectrometer.

Red blood cells and blood vessels belong to the circulatory system, which is responsible for the transport of nutrients, gases, and waste throughout the body.
In the case of the Tyrannosaurus Rex skeleton found by Bob Harmon and later studied by Dr. Mary Schweitzer, the structures which were found that were identical to modern red blood cells and blood vessels belong to the circulatory system. This system in the body is primarily responsible for the transport of nutrients, gases, and waste throughout the body via the blood, which collectively forms in a network of blood vessels, like veins and arteries, and is pushed through these networks by the heart.
