The main target when controlling the acidity of soils is ______. a. neutralizing the pH b. adding base c. replacing lost cation
malfutka [58]

Answer:

C

Explanation:

Acidic soils mean they have more of Al3+ and H+ ions which are acid forming cations. These cations make alkaline forming ions unavailable to plants as nutrients. When the pH of the soil is raised, the Al3+, Fe3+, and H+ are neutralized. The ions bind with –OH ions hence releasing the ions in the negatively-charged sites on the hummus to play a role in the nutrient exchange.

Which of the following is NOT a source of dissolved oxygen in the water?
lesantik [10]

Answer:

A. humans going underwater and exhaling

Explanation:

The dissolved oxygen in water refers to the amount of oxygen that is found in water. However, there are various ways that oxygen dissolves in a body of water, these includes;

- Photosynthesis of aquatic plants: Oxygen is the waste product of the photosynthetic process carried out by green plants. Hence, when aquatic plants undergo photosynthesis, oxygen from them tend to dissolve into water.

- Diffusion from the atmosphere: Oxygen from air or atmosphere also dissolves in water

- aeration as water moves over rocks and debris, and from wind and waves

However, humans do not exhale oxygen but carbon dioxide, hence, it is not a source of dissolved oxygen
