Layer A is the crust and Layer B is the mantle
One option is that the samples run through gel electrophoresis is too small to be recognized (shorter strands of DNA travel further through the gel and larger strands travel shorter). The other option in that the restriction enzyme did not cut the DNA in the proper spot or there was a mutation in the bases that allowed for a mistake in the cutting; that is why there are 800 base pairs in one sample (that's a lot) An example of a mutation is that lets say the restriction enzyme was supposed to cut at the second G in GGACC. But if that G was turned into an A, then the restriction enzyme wouldn't cut there.
For number 5, you might have 800 because of the restriction enzyme cutting it wrong, a mutation that allowed for the cutting to not take place, or a fault in the sample taking.
I am an AP Biology student right now in Wisconsin. I just finished that worksheet this morning :) anymore questions just hit me up
Answer:
A
Explanation:
Vegetative reproduction is a type of asexual reproduction that results in new plant ... Plants have evolved different reproductive strategies for the continuation of their species. ... The flower is the reproductive organ of plants classified as angiosperms. External plant structures such as leaves, stems, roots, flowers, fruits, and seeds are known as plant organs. Vegetative parts include roots, stems, shoot buds, and leaves; they are not directly involved in sexual reproduction. So yes, flowers can be characterized as part of vegetative in means of reproduction of flowers
