Answer:

Take medicine to destroy the germs.

Avoid contact with other people's bodily fluids.

Eat healthful foods such as fruits and vegetables.

Explanation:

For the spread of disease, there is usually a host who bears the infectious agent, the agent exits through a port of exit from the host, is carried by a mode of transmission, then enters a susceptible second host through a port of entry. To stop transmission, stopping the infectious agent can include;

  1. Stopping the agent from leaving the host through port of exit – e.g quarantine the patient
  2. Curtailing the modes of transmission – e.g killing disease vectors
  3. Protecting the ports of entry in the susceptible second potential host – e.g by improving immunity

What technique did Hershey and Chase use in their experiment that led to the conclusion that DNA, not protein, was the genetic m
Olenka [21]

Answer:

They used radioactive labeling techniques to build two different types of phage.

Explanation:

In 1952, a set of experiments were carried out by American biochemists Alfred D. Hershey (1908-1997) and Martha Chase. They prepared two separate virus samples, one contained DNA labeled with a radioactive isotope and the other contained protein labeled with a different radioactive isotope. They grew the two types of viruses separately, infected bacteria with the two sets of phages and analyzed the bacteria for radioactivity. From the results obtained, Hershey and Chase concluded that the viral genetic material was DNA and not protein, reinforcing the observations previously made by Avery.

Do the information given and the map best describe adaptive evolution, convergent evolution, or coevolution? Explain your respon
miss Akunina [59]

Hi, the given question is incomplete, it is missing a diagram, the diagram is given in the attachment below,

Answer:

The correct answer is adaptive evolution.

Explanation:

Based on the given information, it is clear that it best illustrates the phenomenon of adaptive evolution. It is known that different species of finches exhibit an ancestor, which is common, however, all the species have shown adaptation based on the kind of food they are getting within their surroundings.  

The evolutionary modifications that arise by getting adaptive to the specific environment are termed as adaptive evolution. These changes arise due to the phenomenon of natural selection, which further enhances the tendency of reproducing or survivorship after going through some of the challenges presented by the surroundings.

Predict the most likely outcome of culturing transformed E. coli in the presence of tetracycline.Justify your prediction.
My name is Ann [436]

Answer:

E.coli is a bacterium which is preffered for transformation due to its rapid growth and high efficiency of introduction of DNA molecules into cells.

Tetracycline is an antibiotic used to treat several infections such as cholera, plague, brucellosis, and malaria etcetra.

Plasmid is a small, extrachromosomal DNA molecule present in cell which is seprated from chromosomal DNA and have ability to replicate independently.

When a plasmid resistant to tetracycline and kanamycine is inserted into E.coli, the process is called transformation. E.coli might not be able to survive due to absence of plasmid but the transformed strains having antibiotic tetracycline and kanamycine will probably be able to survive it.

Hence, the culture of bacteria carrying plasmid will be able to survive only.
