Answer:

(a)

Protoplanets are built up through the collisions of planetesimals over millions of years. The protoplanets orbit stably around the Sun for a while, but eventually they collide with each other. In about 100 million years, several terrestrial planets, like the ones found in our Solar System, are formed.

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.
