The correct answer is B. Extrusive Igneous

Explanation

The image shows an image of an Obsidian rock and at the top a text fragment that says "The photo below shows a sample of Obsidian forms when lava from a volcanic eruption cools very quickly aboveground"

Igneous rocks are a group of rocks that includes all those that have been formed by the solidification of magma or lava expelled from the earth's lithosphere through a process called crystallization. In general, when the solidification of magma occurs within the lithosphere, the resulting rock is called intrusive. On the other hand, if the cooling occurs (at least in part) at the surface or a shallow depth, the resulting rock is called extrusive.

Taking into account the text that complements the image of the question and the previous information, it is possible to affirm that the correct answer is B. Extrusive Igneous because the rock is the result of the solidification of lava above the ground.

Non-Alaskan grizzly bears are indicator species for mountain ecosystems. In the nineteenth century, the grizzly bear nearly went
borishaifa [10]

Explanation:

Animal indicator list is a barometer to check how a particular ecosystem is affecting the lives of particular animals. The indicator measures  stress or behavior in the ecosystem to know whether to protect  the specie or allow them undisturbed

This is to avoid or reduce to barest minimum incidences of extinction of such specie in the ecosystem.

The grizzly sudden reduction in number from well over 100,000 in California to less than nothing in 1942 triggered  the need to protect the grizzlies from human destruction and possible extinction. Grizzlies was a national specie and appeared in the flag of California. The population gradually reduced in most of the states of Idaho, Utah, Alaska and many more.

The grizzlies in 1975 were declared protected species to avoid being hunted or trapped by humans and to repopulate them in the areas where they once lived. Their future will depend largely on humans ability to allow them to coexist with them, by setting out a large area for them to live and regroup.

This will go to balance the ecosystem which has been tampered or disturbed by development.

What is one conclusion you can draw about changing political boundaries in africa represented on the maps?
frutty [35]

Answer:

The main conclusion that can be determined by observing the map of Africa is that the borders of the nations of modern Africa were determined by the colonial powers that distributed the territories of the continent after the Berlin Conference. Thus, the present borders of the continent do not respect the historical nationalities that the African tribes give each other, with which ethnic conflicts occur in many of these nations, especially in central Africa. Thus, although today it is a practically impossible situation, in case of wanting to respect the historical nationalities of the peoples of the continent, the current national borders should be modified taking into account the ethnic, social and cultural differences of its inhabitants.

Window boxes and other niches in the buildings provide a place to lay a female egg. Peregrines lay their eggs in a nest depression called a “scrape.”
