if a sample known to be about 11,460 years old and has 400 carbon 14 Adams how many atoms are in the sample when organisms just died

There are 1600 atoms when organism just died.

Explanation:

The statement is incorrect. The correct statement is:

If a sample known to be about 11,460 years old and has 400 carbon 14 atoms. How many atoms are in the sample when organisms just died?

The amount of atoms associated with radioactive isotopes decreases exponentially in time by means of the following formula:

(1)

Where:

- Initial amount of atoms.

- Current amount of atoms.

- Time, measured in years.

- Time constant, measured in years.

In addition, the time constant can be calculated in terms of the half-life of the radioactive isotope (), measured in years:

(2)

If we know that , and , then the initial amount of atoms is:

There are 1600 atoms when organism just died.

1: the largest region of the brain is the:

2. the term "psychology" literally means:

the process or procedure of the science or study of the mind.

3. the area of the brain responsible for respiration, heart rate, and smooth muscle control of our blood vessels is t

medulla oblongata

4. the structure that conducts nerve impulses to and from the brain and serves as a reflex center for some sensory information without input from the brain is the:

spinal cord

5. the three-layered membrane that covers the brain and spinal cord and literally means membrane is called the:

meninges

6. the cord-like (string-like) structures that carry bio-electrical impulses from one part of the body to another are called

nerves

7. a group of nerve cell bodies that are found outside of the spinal cord and brain are referred to as:

ganglions or ganglia (pl.) “literal meaning knot”

8. the term that means spinal cord inflammation is:
