Answer:

B

Explanation:

The correct option should be B.

The Astronomical Unit, AU, is a measurement unit for length in general astronomy and represents the mean or the average distance of the sun from the earth.

Mathematically, in astronomy,

1 astronomical unit = 150,000,000 km

But then, 1 km = 0.621371 mile

Hence,

150,000,000 km = 150,000,000 x 0.621371 miles

            ≈93,000,000 miles

Therefore, 1 astronomical unit can also said to be approximately equal to 93,000,000 miles.

<u>The correct option is B</u>

A scientist observes a population crash among eagles within an island ecosystem. Which event might have led to such a crash?
arlik [135]

Answer:

The closing of a dam caused the island to flood.

Explanation:

A population crash is a sudden decline in the numbers of individual members in a population, species or group of organisms. This can be caused by disease, environmental stress (such as pollution), or when its numbers exceed the carrying capacity of its habitat.

Of the four options, the one that would result in the destruction of the habitat and ecosystem which supports the population of the eagle would be flooding of the island due to the closing of a dam.

spin [16.1K]

Answer:No one knows exactly how many species live in the world's tropical rainforests — estimates range from 3 to 50 million species — rainforests are the undisputed champions of biodiversity among the world's ecosystems, containing far higher numbers of species on a per-area basis relative to sub-tropical, temperate, and boreal ecosystems. For example, whereas temperate forests are often dominated by a half dozen tree species or fewer that make up 90 percent of the trees in the forest, a tropical rainforest may have more than 480 tree species in a single hectare (2.5 acres). A single bush in the Amazon may have more species of ants than the entire British Isles. This diversity of rainforests is not a haphazard event, but is the result of a series of unique circumstances.
