The temperature insensitive, thermostable, DNA polymerase was extracted from a bacterium found in hot springs can withstand the high temperatures needed to separate the double stranded DNA and the replication process can continue uninterrupted. The enzyme thermus aquaticus can withstand the high temperature used to separate double stranded DNA, so replication does not need to be interrupted by the need to add more enzymes.
Meiosis
Explanation:
The process in maple trees that decreases the chromosome number in the pollen cells from 52 to 26 is called meiosis.
Meiosis is an important cell division process in which diploid cells are turned into their haploid number.
- In meiosis the cells divides into half and produces four daughter cells from the diploid 2n cells.
- The cell divides twice here. It is common in all sexually reproducing cells.
- It also occurs in all single celled organisms that reproduces sexually.

The data supports the fourth choice, that increasing air temperature and CO2 levels correlate with a decrease in dust concentration.
The first choice is unlikely to reflect dust concentration, and is more likely to be for air temperature. The second choice is false, because the dust concentration is more of a decreasing trend. The third choice is not true, as the spikes in air temperature and atmospheric CO2 concentrations seem to occur simultaneously, implying a positive correlation.
