How Are Radioactive Materials Used to Determine the Age of an Object

question 55

Multiple Choice

How are radioactive materials used to determine the age of an object?

• A)Both the amounts of radioactive and decay material are measured. Using these with the radioactive material's half-life, the age can be estimated.
• B)The amount of radioactive material is measured. Using this with the radioactive material's half-life, the age can be estimated.
• C)The amount of decay material is measured. Using this with the radioactive material's half-life, the age can be estimated.
• D)The amount of heat generated by radioactive dating is measured to determine age.

Definitions:

Schwann Cells

Peripheral nervous system cells that produce myelin, insulating axons to increase the speed at which electrical impulses are conducted.

Multipolar Neuron

A type of neuron characterized by having one axon and multiple dendrites, allowing for the integration of a large amount of information from various sources.

Bipolar Neuron

A type of neuron that has two extensions (one dendrite and one axon), commonly found in the sensory systems like retina and olfactory system.

Neuroglial Cell

Non-neuronal cells in the nervous system that provide support and protection for neurons, playing a crucial role in maintaining homeostasis and forming myelin.
