<em><u>DNA technology has a great and a wide variety of important uses, which ranges from,paternity testing, to matching the DNA samples of suspects collected at a crime scene, to matching relatives to a missing person's DNA.</u></em>
However, <em><u>use of DNA in forensics may have negative consequences which includes, the backlogs of forensic evidence and also present of untested DNA samples which delays the whole process.</u></em>
<em><u>Having untested DNA samples refers to presence of evidence collected from the crime scenes that is untested and instead it is stored in the law enforcement evidence rooms and has not been submitted to crime laboratory to be analyzed. </u></em>
Having untested DNA sample can be considered as the negative consequences of the using the DNA technology. The results of the DNA technology are accepted worldwide in the criminal justice system, in paternity and maternity disputes, and in identification of the missing person. Keeping the untested DNA sample can make the sample useless. Also making report without applying the DNA technology and only using the presumptive test can make the results unconfirmatory.
The cardio-respiratory system works together to get oxygen to the working muscles and remove carbon dioxide from the body. During exercise the muscles need more oxygen in order to contract and they produce more carbon dioxide as a waste product.
