An antibiotic was effective 20 years ago against a specific type of a specific type of bacterial infection no longer works again
Sliva [168]

c. Resistant bacteria have survived and reproduced at a greater rate than nonresistant bacteria

Explanation:

The antibiotic is no longer effective as it was 20 years ago because the resistant bacterial have survived and reproduced at a greater rate than the non-resistant bacteria.

  • The antibiotics have specifically designed to exterminate the disease causing bacteria strain from the body.
  • While at that point in time, it is potent and does the work. Along the line, it will cause the structures of some other strains to change.
  • This will lead to the development of resistant breeds with time.
  • The resistant breed will then be able to survive the onslaught of the antibiotics making it not a good fit.

We used the enzyme, taq polymerase, which is derived from the thermus aquaticus bacterium, in our pcr procedure. Why is this enz
wel

The enzyme Taq polymerase is required in the PCR process because it is the main enzyme that synthesizes the new DNA strands complementary to the template strand and without the activity of this enzyme the PCR will be useless and it cannot make the copy of the given strand in any way. Thus, this enzyme is very much necessary for the efficient working of the PCR.

Polymerase Chain Reaction is a very efficient technique that can able to detect and copy even a small amount of DNA by performing a set of reactions at different temperatures.

The PCR process begins with the denaturing of the template strand at 95°C, followed by annealing in which the appropriate primers bind to the single strands of DNA at 50-56°C, followed by extension at 72°C in which the thermostable Taq polymerase synthesizes the strand complementary to the template DNA.

Is human development best characterized as a slow, gradual process, or is it best viewed as one of more abrupt change?
ankoles [38]

Answer:

Heyya!

Human development is a slow and gradual process. There seems to be slow and gradual change that becomes abrupt change. The mind has many connections and works according to past habits. A person who seeks to improve themselves will gradually change specific areas within their life. After a while there is a cascade effect that causes linked areas to be altered. Skills and methods that required practice and habit forming transition to being a natural part of life.  When the personality suddenly changes, I use the term evolution. Whenever one occurs, the person will probably see their past self as problematic.
