Biology
2 answers:
Vikki [24]3 years ago

Answer: D) The amount of air in a room never changes.

Explanation: Equilibrium is defined as the state in which the concentration of reactants and products is constant or the rate of forward direction is equal to the rate of backward direction.

a) The percentage of nitrogen gas in a room decreases steadily: the amount decreases that means the reaction is taking place in one direction and hence the reaction is not in equilibrium.

b) A blade of grass grows taller : the plant gets taller that means the reaction is taking place in one direction and hence the reaction is not in equilibrium.

c) The amount of water in a cup decreases as it evaporates: The amount of water is decreasing that means the reaction is taking place in one direction and hence the reaction is not in equilibrium.

d) The amount of air in a room never changes: the amount of air does not change as the amount of air leaving the room is same as that of the air entering the room and hence the  reaction is in equilibrium.

(Hello! Could someone help me with this asap? Will mark whoever is first Brainliest.) Nephrons, the functional unit of kidneys,
lidiya [134]

The matching of each situation to the step in the urine formation process where the problem lies are as follows:

  • Step 1: Stella's urine contains protein due to inadequate filtration.
  • Step 2: High toxin levels in the blood are due to Secretion.
  • Step 3: Increased Metabolic wastes are due to inadequate Reabsorption.
  • Step 4: The presence of vital Vitamins in urine is due to inadequate Reabsorption.

Thus, Step 1 belongs to filtration, Step 2 belongs to secretion, and Steps 3 and 4 belong to reabsorption.

<h3>What is the important function of Nephron?</h3>

The important function of the nephron may include the removal of all waste products through urine, secretion of numerous substances, excess water from the blood, etc.

Therefore, it is well described above.

To learn more about Nephron, refer to the link:

What drives deep ocean currents?
OLEGan [10]

Answer:

B) difference in water density

Explanation:

The deep ocean currents are the cold ocean currents. They appear in the Arctic and Antarctic circles. As the warm ocean currents come from the low latitudes toward the high latitudes, they bring in warmer water on the surface. They start to cool off though as the near the high latitudes, so gradually they become cold ocean currents. As they become cold, the water is sinking below the less dense warmer water that is coming from behind, making a turn in the opposite direction and moving as deep ocean current toward the low latitudes. Once it reaches the low latitudes, this water will get warmer, and it will move toward the high latitudes, and the process constantly continues.
