Kelly is crime scene investigator. She is examining a stain that she suspects is blood. Presumptive tests indicate blood, so she is choosing which confirmatory test to use. What are the disadvantages of confirmatory tests? Kelly considers using the test to confirm whether the stain is blood; however, she knows that it could be unreliable because the stain is on a leather boot. Kelly considers using the test, but she believes the stain may be about 35 years old, and this test is not as reliable for stains over 20 years.

acidosis is when the human body attempts to return the bloods ph levels back to normal when the blood is acidic

i think it would be b. tissue because an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.

hope this

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
