D.) none of the above is human induced cause of extinction
Option a is the correct answer
I think its a and b, but i dont know what kind of rock it is. my guess is a metamorphic or sedimentary.
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.V2C1 = 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 =

=

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