I believe it would be 'D' because reprimand means to rebuke something.
Answer:
1. Number of DNA molecules after 30 Cycles of PCR = 1.02 x 10^9
2. No. of mutant DNA molecules = 1.07 x 10^9
Explanation:
1. You just have to take the exponential of 2 to the power of the number of PCR cycles (2^n)
2. All copies were normal at cycle 10 that are about 1024 copies. At cycle 11 single point error, all further copies are mutated.

Scientists developed the time scale by studying rock layers and fossils world wide.
Radioactive dating helped determine the absolute divisions in the time scale. so mass extinction help because there is more to study
During growing season when the plant photosynthesises (spring and summer) they travel down to the roots to be stored.
they go upwards when photosynthesis doesn’t occur (winter) to provide nutrients and cellular energy to parts like the leaves.
hope this is what you needed!!
