Answer:

b. 80g

Explanation:

Three cycles of PCR would produce 3 doublings of the amount of DNA.

Cycle 1: 10x2 = 20pg

Cycle 2: 20x2 = 40pg

Cycle 3: 40x2 = 80pg

This can also be worked out for large cycle numbers by final mass = starting mass x 2ⁿ, where n is the number of cycles.

Is the water we drink today the same as the water that dinosaurs drank? Why or why not?

lesya692 [45]

Answer:

Yes and no

Explanation:

The water we drink today is the same the dinosaurs drank because no new water has been created since. However, the cycling of water in the planet requires for it to travel from one sink to another in a process that may last millions of years. For example, the water the dinosaurs drank may have sank to the bottom of the ocean and remain there for millions of years and thus would technically not be the same that we drink today.
