Answer:
0.325 microliters
Explanation:
1 microgram = 1000 nanograms
DNA sample concentration= 1000 X 0.6 = 600 nanograms / microliters
We need a total of 50 microliter reactions, and the concentration should be 3.9 nanograms per microliter.
So, we need total 50 X 3.9 = 195 nanograms in 50 microliters.
Therefore, it required 195 / 600 = 0.325 microliters of DNA sample to be transferred.
Answer: B
Explanation: because birth and immigration is making the group bigger zero deaths and animals leaving
Most invertebrates leave their young to fend for themselves while vertebrates help their young till they are ready
The biogeochemical cycle in which carbon is exchanged between Earth's terrestrial biosphere, hydrosphere, geosphere, and atmosphere is called the carbon cycle. The global carbon budget is the balance of the fluxes of carbon between these four reservoirs.
