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!
Gulls, crows and herons are all opportunists. They'll eat just about anything that they can get their beaks on. That includes fiddler crabs.

A dwarf is a recessive trait. In order for the plant to be shorter, it would have to have 2 recessive alleles. The plant is also purebread so it wont contain the tall allele. The gametes that are possible are tt.
<span><span>Mitosis is the process in which cells divide to
form new cells. The cell that is being described under the microscope is
already in the Anaphase stage in mitosis.
Anaphase is the process in which two sister chromatids separate and move to
opposite poles of the cell. These two sister chromatids contain identical
copies of DNA that are joined at the middle called centromere. The chromosomes
are separated by the mitotic spindle. Towards the end of the anaphase</span> the two sister chromatids now have their two
separate poles. The mitotic process then proceeds to the
Telophase.</span>
