Answer:
Most peppered moths used to be grey with dark spots, but have evolved to be mostly black. This is because pollution from the Industrial Revolution threw soot on the trees causing them to look black. This gave the black moths camouflage from predatory birds meaning they survived and reproduced. By survival of the fittest, the peppered moths became black like the trees.
Explanation:
The second generation was the one that was allowed to self pollinate
, is a form of asexual reproduction<span> and cell division </span><span>used by all poekaryotes</span><span> (bacteria and archaebacteria) and some organelles within eukaryotic</span><span> organisms.</span>
After the 1st half-life 250 g of the radioactive material will be left.
<span>After the 2nd half-life 125 g of the radioactive material will be left. </span>
<span>After the 3rd half-life 62.5 g of the radioactive material will be left. </span>
<span>Therefore after 60 minutes, 3 half lives would have occurred. </span>
<span>Therefore the half-life = 60 / 3 = 20 minutes when 250 grams of the original material would have remained radioactive. </span>
<span>Therefore the answer is A) About 250 gram of the material decayed in 20 minutes.</span>
