ILL GIVE BRAINLIEST PLZ HELP. Atoms of carbon-14 are radioactive. They decay into atoms of the element nitrogen. Suppose that a sample of rock is taken from a fossil. The sample has 500 atoms of carbon-14 and 1500 atoms of nitrogen. If carbon-14 has a half-life of 5700 years, how old is the fossil? 5700 years old 11,400 years old 17,100 years old 2850 years old

11,400 years old

Explanation:

The total  number of atoms present at the beginning = number of C-14 + number of N-14 atoms.

Hence;

1500 + 500 = 2000 atoms = No

At time t, N = 500 atoms of C-14 remains

Since the half life of C-14 (t1/2) = 5700 years

N/No = (1/2)^t/t1/2

500/2000 =  (1/2)^t/5700

1/4 = (1/2)^t/5700

(1/2)^2 =(1/2)^t/5700

2 = t/5700

t = 2 * 5700

t = 11,400 years old

raits that your monster will have. the dna code for each trait is given, so you will need to go through the process of transcription and translation to determine what protein is being made and then match that with the corresponding trait. you may even include a picture of your monster if you are feeling creati

where is the scientific experiment?
