They turn brown because they begin to decompose..which is why bananas are biodegradeble because they are able to become decomposed by other living things
It depends.... lets say that a mom is a carrier of colorblindness, so only one of her sons will have colorblindness and one of her daughters will be a carrier but if it is on both X's (of the female's) then both of her daughters will be carriers and her sons will both be colorblind.
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!
<span>the main difference between the two is ivertebrates doesnt have no backbone or spinal cord... vertebrates do have a back bone like humans</span>
