Because the rays of the light might reflect and crack the lens
Answer:
Yeah, so basically the image is showing restriction enzymes. The job of restriction enzymes is mainly involved in research when scientists use them for cloning human genes. But that's besides the point...
Main thing you have to understand is that restriction enzymes cut at very specific places along DNA sequences. If you look at the restriction enzyme Rsa 1, you can notice that it cuts only between a thymine nucleotide base and an adenine nucleotide base. Next, if ya look at Sty 1 (be careful b/c W can represent adenine or thymine), it cuts only between two directly adjacent cytosine nucleotide bases!
SO.... if we go to Rsa 1, we can find the answers by dividing up the sequences between the pattern we saw in the gray box. It only cuts between adenine and thymine bases. Based on that, we can find the number of fragments created, and the segment lengths (basically just like how many nucleotide bases are in each strand). Hope ya found this helpful!
The three methods of carbon dioxide transport in the blood are dissolution in blood plasma, binding to hemoglobin, and carried in the form of bicarbonate. About 7% of the carbon dioxide is dissolved in the blood plasma. The majority of the remaining 93% is carried as part of the bicarbonate buffer system while the rest binds to hemoglobin.
