Answer:
Indicator species
Explanation:
Indicator species refers to the species whose presence or absence in particular ecosystem indicates about the condition of the ecosystem.
In the given question, the stonefly which cannot survive if the dissolved oxygen in the water gets reduced as a result of the pollution indicates that the ecosystem or habitat has some pollutants which have decreased the level of DO in the aquatic habitat.
Thus, the indicator species is the correct answer.
Adding nutrients to the soil allowed more sunflowers and more birch trees to sprout over the three-week period. Also, by adding nutrients, the sunflowers and birch trees that sprouted were able to grow taller than those without added nutrients
The answer is false...
Eukaryotes have unicellular cells and the majority of eukaryotes are multicellular.
Prokaryotes are unicellular only.
Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. Enzymes are highly selective catalysts, meaning that each enzyme only speeds up a specific reaction. Hope I’ve helped ;)
