Explanation:
The foliage on roadside vegetation is damaged when salted water sprays up from the pavement by passing vehicles. Salt-laden water can also percolate down through the soil profile, coming into contact with soil particles, soil microbes, and plant roots. Salt injures vegetation by: Increasing water stress
which of these is a source for particulate matter in the air?
Answer:
Particulate Matter (PM) Sources Components of particulate matter (PM) include finely divided solids or liquids such as dust, fly ash, soot, smoke, aerosols, fumes, mists and condensing vapors that can be suspended in the air for extended periods of time.
Explanation:
Automobiles, dust, and fires are source for particulate matter in the air. Therefore option D is correct.
Particulate matter (PM) refers to tiny particles suspended in the air that can have harmful effects on human health and the environment. Sources of particulate matter in the air include automobiles, dust, and fires.
Automobiles emit exhaust emissions that contain particulate matter, especially from diesel engines. Dust particles can be generated from various sources such as construction sites, unpaved roads, and agricultural activities.
Fires, including both wildfires and controlled burns, release smoke and ash particles into the air. These particles can vary in size and composition.
All of these sources contribute to the presence of particulate matter in the atmosphere, and their emissions can have detrimental effects on air quality and public health if not properly managed or controlled.
Therefore option D all of the above is correct.

according to plato, where do souls have to drink before starting their new lives on earth?
According to Plato, the souls of people tend to reincarnation, that is, the souls of each person have had previous lives in which they have developed and have had different experiences.
Thus, as a way to generate an impartiality of the soul, which allows it to start a new life without influences on previous lives, they should drink water from the River of Forgetfulness.
This made the souls unable to remember anything from their previous lives or the adrenal world in which they were before coming back to life.

Explanation:
if a cell were placed in an isotonic environment relative to the cell, water would __.
Answer:
If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell’s volume will remain stable. If the solute concentration outside the cell is the same as inside the cell, and the solutes cannot cross the membrane, then that solution is isotonic to the cell. Tonicity in living systems
Explanation:
If a cell were placed in an isotonic environment relative to the cell, water would move across the cell in both directions, but the cell size remains the same throughout the conditions. The cell will remain flaccid.
What do you mean by Isotonic solution?
An isotonic solution may be referred to as a solution in which the concentration of water is the same as that of the cell.
If a cell resides in an isotonic solution, there will be a net flow of water into or out of the cell, but movement takes place in such a way that the volume of the cell remains the same.
Therefore, If a cell were placed in an isotonic environment relative to the cell, water would move across the cell in both directions, but the cell size remains the same throughout the conditions. The cell will remain flaccid.

12.What is an invasive species?
A native species which are added to an area
A keystone species in an environment
A non-native species added to an area
Answer:
An invasive species is an introduced organism that becomes overpopulated and negatively alters its new environment. Although their spread can have beneficial aspects, invasive species adversely affect the invaded habitats and bioregions, causing ecological, environmental, and/or economic damage.
To be invasive, a species must adapt to the new area easily. It must reproduce quickly. It must harm property, the economy, or the native plants and animals of the region. Many invasive species are introduced into a new region accidentally
A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. ... Any organism, from plants to fungi, may be a keystone species; they are not always the largest or most abundant species in an ecosystem
An invasive species is an organism that is not indigenous, or native, to a particular area. Invasive species can cause great economic and environmental harm to the new area.

Answer:
True.
Explanation:
Bryophytes lack the conventional vascular tissues which usually contain the substance lignin. Without vascular tissues, these plants have no means of transporting water and/or nutrients from their lower organs to the higher organs which explains their limited height.
