<span>the nurse should dispose the dressing in a red bag labeled as hazardous material. Remember that any material coming from an infected patient is considered as infectious. it is potentially infectious to the human body, especially to those who are immunocompromised. Vancomycin resistant enterococci is a bacteria which is resistant to the antibiotic Vancomycin. it means this type of antibiotic is not working to kill the bacteria, moreover this type of bacteria is highly infectious that's why precaution is observed. </span>
A) DNA fulfils all three conditions:
<span>(1) copy itself precisely - in the process of replication, DNA copies itself and two molecules of DNA are formed. This process is very precise thanks to the great number of proteins involved in these process that prevents error occurring and proteins that can fix the error if it occurs.
(2) be stable but able to be changed - DNA is very stable molecule otherwise, it cannot be a genetic material. However, its chains can separate in a short length so the translational machinery can attach to it and the process of transcription can occur. Also, in crossing over, during meiosis, </span>the exchange of genetic material occurs and chromosomes change a bit.<span>
(3) be complex enough to determine the organism’s phenotype - it contains a number of genes responsible for different traits. All of this results in the </span>organism’s phenotype.
B) DNA copies itself. <span>Meselson and Stahl conducted the experiments on DNA replication in which they used </span>E. coli<span> bacteria as a model system. After they labelled all bacteria's DNA with heavy 15N by using medium with heavy 15N, they switched bacteria to medium with light 14N. After several generations, all bacteria's DNA was labelled with light 14N. This experiment evidenced that the self-replication of DNA is semi-conservative process.</span>

Answer:
for starters we pollute the air and were causing global warming with all the c02 in the air, its really a toll on our atmosphere point blank
and were taking up space where the animals live
Explanation:
<span>work together to perform one or more functions</span>
