An open circulatory system simply
means that the blood flows out of vessels and into the spaces or sinuses. Invertebrates,
insects and crustaceans has an open circulatory system where pump blood goes
into a hemocoel and diffusing back to the circulatory system between cells. In
other animals, the heart pumps the blood into the body cavities, spaces or
sinuses, where the blood surrounds the tissues.

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.
