Answer:

radiometric dating methods

Explanation:

The oldest rock layer will be at the very bottom, and as time goes on, more layers will form making the top layer the youngest layer and the bottom layer the oldest. This method can determine the amount of radioactive decay of certain elements which can help them make a geologic time scale.

G you extracted your dna from cheek cells. the concentration of your dna sample is 250 ng/μl. the dna template for pcr should be

Karo-lina-s [1.5K]

You should mix 4µl of DNA sample and complete it with 96µl (100-4) of water.

You can figure this out by using C1.V1 = C2.V2
C1 = 250 <span>ng/μl (Sample Concentration)
</span>V1 = ? (the necessary volume to take from the DNA sample)
C2 = 10 <span>ng/μl (PCR concentration)
</span>V2 = 100 µl (total volume)

V1 = $\frac{C2 . V2}{C1}$ = $\frac{10 . 100}{250}$ = 4µl

For the water: 100µl (total volume) = 4µl + Water
Water volume = 96µl
