Snowcat [4.5K]

Answer:

The correct option is A

Countercurrent multiplication is the process whereby energy is used to generate an osmotic gradient in which water is reabsorbed from the tubular fluid to produced concentrated urine.

Explanation:

Countercurrent multiplication moves sodium chloride from tubular fluid into interstitial space deep within the kidneys. The concurrent multiplication process build up osmotic gradient interstitial fluid in a single effect. Here, sodium chloride is driven by active transport out of the tubular fluid in the thick ascending limb into the interstitial fluid, which becomes hyperosmotic. This result to water moving passively down its concentration gradient out of the tubular fluid in the descending limb into the interstitial space to a point where it attains a state of equilibrium.

Therefore,the correct option is A, where the ions leaves the ascending limb to make water comes out of descending limb.

Name two examples of catastrophic events which could lead to a mass extinction?
Lemur [1.5K]

Asteroid impact

Volcanic eruptions

Explanation:

Asteroid impact and volcanic eruptions are two common events that could lead to a mass extinction.

A mass extinction is an abrupt decrease in life on earth due some catastrophic event.

  • The collision of a large bolide on the surface of the earth is a catastrophe in itself.
  • The collision and its aftermath have destructive consequences on life.
  • The force of the collision can reverberate in form of vibration throughout the earth.
  • It can cause heating of the earth surface.
  • Volcanic eruptions can become global phenomenon that upsets the earth balance.
