21) Hurricanes will form under the right ingredients. Name two ingredients necessary for hurricane development.
One of the necessary ingredients for a hurricane to form is the accumulation of thunderstorms that travel over the warm waters of the ocean.
The warm air of the storm and the air of the ocean surface combine and begin to rise. This generates low pressure on the surface of the ocean.
Another important ingredient are thewinds that move in opposite directions, which cause the storm to begin to spin.
There are two different species of toads which are separated by a hot and dry valley, and fossil evidence indicates that these two species share a common ancestor. What would have caused these two species to evolve?
Answer: Adaptive Speciation
The two species evolved as s result of adaptive Speciation.
Adaptive speciation occurs when biological interactions induce disruptive selection and the evolution of assortative mating, thus triggering the splitting
understanding processes of adaptive speciation, in which the splitting of lineages is an adaptation caused by frequency-dependent selection. Adaptive, or sympatric, speciation has been modeled since the 1960s.
In evolutionary biology, adaptive radiation/speciation is a process that makes living organisms diversify and change rapidly from an ancestral species into several new forms, especially when a change or natural event in their environment makes new resources available, thereby creating new challenges and opening new environmental niches.
Explain all the types of erosion caused by water
There are three types of soil erosion caused by water. They are: Sheet, Rill and Gully.
This type of erosion takes away the top soil over a wide area thereby making it look as though it took a sheet of the top soil. As a result, this is not easy to notice at first glance because the soil from the whole area is gone so there is nothing to compare it to.
When water goes in channels and makes lines in the soil a by carrying off the soil that was previously on those lines, that is rill erosion. These channels must be shallow to be considered Rill erosion however because if they are too big, it would become gully erosion.
Gully erosion is much like Rill erosion but on a much larger scale. With gully erosion, the channels are much bigger and allow for more soil to be taken. Gully erosion can remove a lot of soil from an area. The Grand Canyon for instance was formed by Gully erosion.

Why are prices described as a no-cost alternative when allocating scarce resources?
Upon recent confabulations, price descriptions per allocation of resources is exceedingly stark. Alternatives to this would be the most prevalent market in wheat.
