16 + b^2 = 324

-16              -16

b^2 = 308

square root them

b = 17.55

Step-by-step explanation:

1 Independent

Since you know there are 5 republicans for every 4 democrats you can divide 55/5 and get 11. Then you would multiply 11 by 4 for the number of Democrats. Then you would add 55+44=99. So there would be 1 independent.

Some highly-conserved regions of the human genome (similar to comparable regions in other species) don't code for proteins. Why? 1. Such regions coded for proteins in genomes of distant human ancestors, but over time they became noncoding; however, conserving their sequence remained unchanged.2. Such regions play a significant role in gene regulation. That is why they remain conservative under the influence of natural selection.3. Such regions are the sites of DNA recombination. They should remain conservative to provide an accurate recombination process during cell division.4. Such regions remain conservative because the mutation rate differs along the genome. In other words, such regions remain conservative accidentally. 1: active or passive? Watercolors had been used by the illustrator. 2: active or passive? Lucinda had planted those marigolds.
