Answer:
1. They usually host three or more ecosystems where animals can’t live.
4. They usually host one ecosystem with a variety of plants
Explanation:
A mountain ecosystem has more than one ecosystem. This is mainly due to the diversity of climate that this environment promotes. Due to its proximity to the ocean, slope and elevation, the mountain ecosystem promotes different areas that create different ecosystems, some more humid and others drier.
In this environment there is usually a wide variety of plants, but not animals.
Although the light year is a
commonly used unit, astronomers
prefer a different unit called the parsec (pc). A parsec, equal to 3.26
light years, is defined as the distance at which 1 Astronomical Unit subtends an
angle of 1 second of arc (1/3600 of a degree) When we use the parsec for really
large distances, we often put a prefix in front of it - like kiloparsecs (kpc),
which are equal to 1000 parsecs - or Megaparsecs (Mpc), equal to a million
parsecs.
The Milky Way is about 1,000,000,000,000,000,000 km
(about 100,000 light years or about 30 kpc) across. The Sun does not lie near
the center of our Galaxy. It lies about 8 kpc from the center on what is known
as the Sagittarius arm of the Milky Way.
<u>ANSWER:</u>
The answer is A. If the structure of a building is built with earthquake-resistant materials, it does not affect the amount of destruction caused by earthquake vibrations.
<u>EXPLANATION:</u>
- Especially in the countries that are prone to an earthquake, houses and building should be carefully planned and built in order to withstand an earthquake.
- The bricks should be held in place with the right mortar. Also, the base of the building should be made stronger rather than the top floors.
- Steel-framed buildings and good pillared buildings also tend to survive powerful quakes and vibrations.
