Give two reasons why dna evidence analysis is an imperfect science

Biology
1 answer:
Virty [35]3 years ago
7 0

Answer:

DNA samples might be planted and it is possible to synthesize a nucleotide sequence to incriminate a person

Explanation:

In a criminal case, DNA evidence may be considered to be fraudulent because DNA samples might be planted around the crime scene. Moreover, specific genomic profiles of an individual stored in the database can be used to manufacture a DNA sample matching this profile without the necessity to obtain tissues of the person. In consequence, DNA evidence may be considered to be imperfect. Nonetheless, it is important to highlight that DNA evidence is one of the most important modern advances used during criminal trials, and it has proven to be a very useful (and effective) tool available in law enforcement.

Setler79 [48]

Animals with a three-chambered heart would include Amphibians.

  • Amphibians have three-chambered which comprises of two Atria and one ventricle. Examples of Amphibians include Frog, Toads, Salamanders.
  • In Amphibians heart blood from the single ventricle travels to the lungs, skin, and body, where it is oxygenated. Before being pumped out of the heart, deoxygenated and oxygenated blood are mixed in the ventricle.
  • This is because the Amphibians have low rate of metabolism and thus requires less oxygen for their metabolism.
  • As a result heart's load to deliver oxygenated blood to body is lowered.

Thus, from the above pointers we can conclude that only Amphibians from the option have three-chambered heart.
