A buffer solution is made up of a weak acid and its conjugate base or a weak base and its conjugate acid. The two components maintain a pH balance that resists change when strong acids or bases are added to it.
One of the main pollutants present in the troposphere are the ozone precursors, which is a group of pollutants, primarily generated during the combustion of fossil fuels. Reaction with daylight ultraviolet (UV) rays and these precursors create ground-level ozone pollution (Tropospheric Ozone). Ozone is known to have the following health effects at concentrations common in urban air.
Explanation:
Keystone species are animals that help manage other animal species by controlling population numbers and biodiversity within an ecosystem. The impacts of keystone species are usually greater than their numbers.
owls can be a great benefit to places where rodent populations are high. Dense urban areas often suffer from an abundance of rats and mice spreading disease, and rural agricultural communities have their crops consumed and soil eroded from burrowing voles and field mice. Without owls, and other top predators, rodent populations could explode and exacerbate the effects they produce.
Water
This flowering plant does not wilt but stands straight up, reaching toward the sunlight, because its cells contain mostly water.
Water is ultimately important to the life of plants as it allows plants to perform its everyday processes by supplying plant’s essential nutrients. When a plant cell is filled with water, it pushes firmly against the cell walls. This effect is known as turgor pressure and it makes the structure of plants (stem tissues and leaves) to become rigid, allowing it to stand upright and prevent it from wilting.
