Answer:
All natural soils are heterogeneous mixtures because no two nature soil samples will have the precise proportions of its inherent components.
Explanation:
Answer:
The microbes thriving in acidic environments are termed as acidophiles, and these range from eukaryotes to bacteria and archaea, which are mainly found in diverse acidic surroundings like sulfuric geysers and pools, in the human stomach, and in the regions that get polluted by acid mine drainage.
The mentioned case is not entirely correct as the protons found in the acidic surroundings are not utilized for the generation of ATP as they are not originating from within the cell. In order to sustain their internal acidic pH, the acidophiles exhibit adaptations like the presence of the negatively charged proteins on the surfaces of their membranes so that they can prevent deterioration due to acidic surroundings.
Like all life on earth, plants need water to survive and grow. Indeed, like humans, water is the primary element that makes up the structure of plants. Human bodies are comprised of around 70 percent water, but in plants this proportion can be as much as 95 percent. Water is also essential to the way a plant receives nutrients and provides energy for itself. Thus, water is arguably the most essential substance required by plants. That is why many elements of permaculture design – from using swales and contouring to slow runoff from the land and allowing it to sink into the soil to mulching to prevent evaporation of moisture from the soil surface – emphasis the preservation of water so that it can be provided to plants.
