1. Answer;
Monkey
Explanation;
-Scientists can compare the DNA of two organisms; the more similar the DNA, the more closely related the organisms.DNA-DNA hybridization, this process hybridizes the genetic information from two different organisms to determine similarities between them.
-In this case the DNA of housefly, bettles , butterfly and grasshopper are very similar as they are closely related organisms.
Therefore; Monkey's DNA would be expected o be least similar to the housefly’s.
2. Answer;
The sample yields very little DNA,
which means that it must be amplified to produce enough quantity to detect on a gel
Explanation;
-Polymerase chain reaction, or PCR, is a technique used to take a piece of DNA and make many copies of it. This technique is very similar to the natural process which cells use to make new copies of DNA, but it is also a little different.
-PCR is a necessary step in the analysis of a DNA sample taken from a crime scene because the sample yields very little DNA, which means that it must be amplified to produce enough quantity to detect on a gel.
<span>Well, since there is little genetic variation, all the animals in the population are fairly similar, from a purely physical standpoint. Therefore, if there was some new form of whale lice that kills northern right whales, then presumably at least nearly 1/3 of the population would be vulnerable to this new form of whale lice. This is over simplified, but in essence a huge portion of the population is much more vulnerable to a single threat due to common disease resistances, or the lack thereof.</span>
Answer: biological food contamination

Answer:
water
Explanation:
the molecular structure of water is H2O, where the O stands for oxygen.
