be over a hot spot, which is why it is the only one of the seven large islands that has active volcanoes. What should be TRUE of
laiz [17]

Answer:

What should be <u>TRUE</u> of the island of <em>Hawaii</em> :

  • Scientists in search of ongoing speciation events are more likely to find them here than on the other six large islands.
  • Its species should be more closely related to those of nearer islands than to those of farther islands.
  • It should have a rich fossil record of terrestrial organisms.

Explanation:

In cases of <em>geographic isolation</em>, and subsequent speciation, produced by dispersal and colonization phenomena we can find the island of Hawaii. Adaptation to these environments can be the trigger for divergence. The <em>large number of species</em> in this archipelago, more than 500, seems to have emerged  through<em> migration</em> and diversification. Many of these are endemic to a nearby island, and the subsequent<em> evolutionary divergence.</em>

The volcanic islands, which have never been in contact with the continent, are especially<u> rich in endemic species; </u>the species that inhabit them are descendants of those who arrived in times past and <u>were able to adapt.</u>

Almost ninety years ago, in the south of the island of Hawaii, they revealed some <u>bones </u>that turned out to be the<u> first bird fossils discovered i</u>n the archipelago. The bones were under a flow of prehistoric lava and on a bed of volcanic ash.

In short, the Island of Hawaii is of great interest to scientists and there are always new developments buried years ago by volcanic activity.

2. Socialist systems often have mixed economies because the state
Fudgin [204]

In the socialist systems the state shares economic control with private enterprise.

Explanation:

The socialist systems are systems where the economy is of mixed type. This is due to the transitional nature of the socialist system, so it has elements of both the system from which it is moving away, and from the system toward it is striding to. In general, it is traditional or market economy from which this system is moving away and transforms into communism, though there are few exceptions that are in the opposite manner.

While the private enterprises are allowed to exist and prosper, there are some limitations, as they are often obligated to be business partners with the state and have to stick to the state's rules. Also, the state is a powerful player on the market, owning and controlling the most important resources and infrastructure.
