Verizon [17]
Clouds form as a result of the condensation of water vapor in the atmosphere. They are made of tiny droplets of water. Clouds tend to form between 3pm and 6pm because this is when the region starts to loose or has completely lost the heat form the daily sun. Water vapor will condense once temperatures are low or are decreasing.

In addition to E. coli, a risk factor for development of pyelonephritis is: a. urinary retention and reflux. b. nephrotic syndro
monitta

Answer:

One of the factors for the development of pyelonephritis, in addition to E. coli, is urinary retention and reflux (option a).

Explanation:

Pyelonephritis is an infection of the upper urinary tract caused by bacteria in the urine, such as Escherichia coli.

Under normal conditions, urine in the urinary bladder is aseptic, that is, without bacteria.  The presence of bacteria in the urine indicates a urinary infection.

Urinary retention is the limitation of the expulsion of urine from the bladder. This promotes:

  • <em>An increase in the amount of bacteria present in the bladder. </em>
  • <em>The pressure generated by urine retention causes the bladder to generate a retrograde flow - reflow - towards the ureters, leading the bacteria to the kidneys. </em>

The result of urinary retention and reflux - when bacteria are present - is an infection in the upper urinary tract, called pyelonephritis.

When antibodies bind antigens, the clumping of antigens results from _______. A. the antibody having at least two binding region
Pani-rosa [81]

When antibodies bind antigens, the clumping of antigens results from the antibody having at least two binding regions.

What's the function of the antibody-antigen complex?

Antibodies serve two primary functions: selective binding to antigens to initiate an immune response and activation of other immune system components to combat infections.

  • Immunoglobulins' capacity to combat a wide range of diseases is based on their inherent ability to distinguish between distinct antigens.
  • Because of their antigen specificity and affinity, antibodies have shown to be a significant and important tool in research, diagnosis, and treatment.
  • Although it appears to be a straightforward move, the connection of an antibody and its antigen to form an antigen-antibody complex is made up of a plethora of non-covalent interactions.

Hence, the correct answer is option A
