The difference would be that impervious structures and surfaces generally do not allow molecules and compound to be transferred across. It is generally impossible to get something through an impervious surface. This isn't true, however, for pervious surfaces.
Answer:
<em>3 types of front: cold front (cool air and cumulus clouds are replaced by stratus and stratocumulus clouds or clear skies) , warm front ( warm air and high clouds like cirrus), and stationary front(warm and cool air and stratus, nimbostratus, altostratus, and cirrostratus clouds. </em>
Explanation:
Cold fronts form when a cooler air mass moves into an area of warmer air in the wake of a developing extratropical cyclone. The warmer air interacts with the cooler air mass along the boundary, and usually produces precipitation. Cold fronts often follow a warm front or squall line.
Warm front Forms when a moist, warm air mass slides up and over a cold air mass. As the warm air mass rises, it condenses into a broad area of clouds. A warm front brings gentle rain or light snow, followed by warmer, milder weather.
Stationary front Forms when warm and cold air meet and neither air mass has the force to move the other. They remain stationary, or “standing still.” Where the warm and cold air meet, clouds and fog form, and it may rain or snow.
Answer:
e. vertebrate
Explanation:
The question states that the organism posses the following characteristics:
- Low biotic potential: this means that the maximum amount of offpring that this species can produce under best environmental conditions is actually low. Typically, large organisms have much lower biotic potential than smaller ones.
- k-selected: this means that this species typically invest much more in fewer offspring rather than prioritizing many offspring.
- iteroparous: means that can reproduce many times over one organisms's lifetime.
- heterotrophic, fed upon by top carnivores large body size (> 2m tall): this shows that they are preys of large carnivores, thus it implies that the prey itself has a considerable size and it is not a plant.
Option a is discarded as seed cones are produced by conifers which are autotrophics.
Option b is incorrect as basidiocarps are typical of Basidiomycetes (fungi) which are not large and are rarely consumed by carnivores.
Option c and d correspond to small animals (e.g. arthropods) and with usually high biotic potential and r-selected species which prioritizes high growth population rates and offspring.
Then, option e (vertebrate) is consistent with belong to a k-selected, low biotic potential, iteroparus, heterotrophic species (e.g. a mammal).
When coal is burned the sulfur mixes with oxygen and the sulfur oxides are emitted to the atmosphere. Sulfur dioxide (SO2) becomes sulfur trioxide (SO3) when responding with oxygen in the air.
<h3>How does combustion cause acid rain?</h3>
Power plants remove the major of sulfur dioxide and of the nitrogen oxides when they burn fossil fuels, such as coal, to make electricity.
The from cars, trucks, and buses remove nitrogen oxides and sulfur dioxide into the air. These pollutants leads acid rain.
Hence, This reaction with water elements in the atmosphere to form sulfuric acid, a strong mineral acid. This makes rain acidic.
