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.

Looking at the drawing carefully, the message the artist was trying to pass about invasive species is that they are monsters that suffocate, hinder, or devour other species found in the environment.

Generally, invasive species are species of living organisms that have the capacity to outcompete other species in any environment they are introduced to. Invasive species operates using different strategies. Some of the strategies include:

  • high rate of reproduction
  • high rate of survival
  • secretion of chemicals that kill or inhibit the growth of other species in the environment
  • high dispersal rate

Using different combinations of these strategies, invasive species gradually take over any environment they get introduced to once they get themselves acclimatized to it.
