Answer:

Stars shine brightly because they are hot and made up of gases. As we know that the fire gives off the light.

They are a source of energy and nuclear reactions continuously takes place there.

The best example is the sun which shines so bright because of the nuclear fission in it. the hydrogen is converted into helium continuously and this process emits heat and light.

Answer:

May not

Explanation:

Adaptation is made possible as a result of an organism being exposed to different environmental conditions. These exposure makes it adopt different techniques for its survival which eventually results in it being adapted to the condition and is then passed on as traits to its offsprings. They are then able to survive when met with such environmental condition.

When an organism is exposed to the same conditions all the time then there is lack of genetic variation and adaptation may not occur.

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.
