Bacteria cells can be used to produce insulin for the treatment of diabetes in humans. Which best explains how the bacteria cells are able to produce insulin for humans? (8.L.2.1) *
A. The bacteria have been grown on a petri dish containing insulin.
B. The bacteria have been genetically engineered to contain the DNA needed to produce insulin.
C. The bacteria have been exposed to radioactivity to create mutant strains capable of producing insulin.
D. The bacteria have been grown on a petri dish containing sugar; the bacteria produce insulin in response to the sugar.
Answer:
Your answer is B), I took this quiz already.
The statement 'bacteria have been genetically engineered to contain the DNA needed to produce insulin'' BEST explains how bacterial cells are able to produce insulin for humans (Option B).
Recombinant DNA (rDNA) refers to the genetic engineering strategies used to create genetically modified organisms capable of expressing exogenous DNA sequences.The rDNA technologies involve the use of specific proteins that cut (restriction enzymes) and paste (ligase enzymes) target nucleotide (DNA) sequences in order to design organisms containing such sequences.The recombinant DNA can be expressed into a suitable vector (in this case, bacteria) in order to produce a protein of interest (e.g., insulin).In conclusion, the statement 'bacteria have been genetically engineered to contain the DNA needed to produce insulin'' BEST explains how bacterial cells are able to produce insulin for humans (Option B).

what are the three domains in the new system of taxonomy.
Answer:Domain is the highest taxonomic rank in the hierarchical biological classification system, above the kingdom level. There are three domains of life, the Archaea, the Bacteria, and the Eucarya.According to this system, the tree of life consists of three domains: Archaea, Bacteria, and Eukarya. The first two are all prokaryotic microorganisms, or mostly single-celled organisms whose cells have no nucleus. All life that has a cell nucleus and eukaryotic membrane-bound organelles is included in Eukarya.

Answer in terms of livor and rigor, what stages and where in the body is it present
Answer:
The common cold and the flu may seem very similar at first. They are indeed both respiratory illnesses and can cause similar symptoms. However, different viruses cause these two conditions, and your symptoms will gradually help you differentiate between the two.
Both a cold and the flu share a few common symptoms. People with either illness often experience:
a runny or stuffy nose
sneezing
body aches
general fatigue.
As a rule, flu symptoms are more severe than cold symptoms. Another distinct difference between the two is how serious they are. Colds rarely cause additional health conditions or problems. The flu, however, can lead to sinus and ear infections, pneumonia, and sepsis. To determine whether your symptoms are from a cold or from the flu, you need to see your doctor. Your doctor will run tests that can help determine what’s behind your symptoms. If your doctor diagnoses a cold, you’ll likely only need to treat your symptoms until the virus has had a chance to run its course. These treatments can include using over-the-counter (OTC) cold medications, staying hydrated, and getting plenty of rest.If you have the flu, you may benefit from taking an OTC flu medicine early in the virus’ cycle. Rest and hydration are also very beneficial for people with the flu. Much like the common cold, the flu just needs time to work its way through your body.
