The outer core is about 1,400 miles thick, and it's made mostly of a combination (called an alloy) of iron and nickel, along with small amounts of other dense elements like gold, platinum, and uranium. These metals can, of course, be found on the surface of Earth in solid form.

Answer:

4. if  if it can outcompete native species or If the species has evolved under great competition or predation

5. area of habitat connecting wildlife populations separated by human activities or structures

6. Habitat corridors allow movement between isolated populations, promoting increased genetic diversity, they also provide food and shelter for a variety of wildlife

7. Because of the trophic pyramid

8. the change in the frequency of an existing gene variant in a population

9. Models for biologists, geneticists and ecologists to understand extinctions

10. Mutualism is the interaction between two or more organisms where both organisms can benefit from the interaction and Commensalism is when two species interact, however only one benefits but the other is not harmed.

11. the first one is producer

the second one is a Primary Consumer

the third one is a secondary consumer (there are actually four so I will put that as well)

the fourth one is a Tertiary Consumer

13.  An endangered species is a species that is very likely to become extinct in the near future

14. An invasive species is a species that negatively impact their environment for example, a lionfish

15. the THREE (I think your paper is mixed up a bit btw) types of biodiversity are Genetic diversity, species diversity, and ecological diversity

16. I am unsure of this one, sorry!

17. a keystone species is is a species that if they were removed from their ecosystem it would make a huge difference - the reason this is so important is because, a keystone species is an organism that helps define an entire ecosystem

Indicator species are organisms that can tell us about the levels of pollution in an area by their presence or absence- they are important to scientists because, they indicate the water quality of an ecosystem.

18. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene

19. No other species would be able to fill its ecological niche, the ecosystem would be forced to change

Explanation:

Sorry this took so long

also, I learned about all of this last year in Biology in my Freshman year of high school, good luck!

One cause for plate motion is plate pull. which of the following best describes plate pull
Stella [2.4K]

Answer:

C. When the oceanic lithosphere, which is more dense, sinks and pulls the plate with it

Explanation:

Slab pull and other mechanisms are responsible for the motion of plates. Every tectonic plate is driven by mantle convection.

  • Convection is a form of heat transfer in fluids.
  • It is as a result of differences in density and temperature values.
  • The oceanic crust is denser and colder.
  • As hot magma from deep within the subsurface rises and move through cracks, the oceanic lithosphere is drawn down and deeper.
  • This cycling between the cold lithosphere and hot rising plumes provides the mechanism that drives plate motion.

Now that you understand the basics about the Berlin Airlift, formulate three questions about this event that you want to know mo
tangare [24]

The correct answer to this open question is the following.

The three questions about the Berlin Airlift are the following.

1.- Why did Soviet leader Joseph Stalin order such an "evil" thing?

2.- What was the reaction of the western European allies to that decision?

3.- How everything ended after almost one year of the blockade?

Here are my answers.

1.- Why did Soviet leader Joseph Stalin order such an "evil" thing?

The Soviet Union needed to have a powerful answer against the allied forces after the recent events. Furthermore, Joseph Stalin wanted to show his power. After Joseph Stalin ordered the blockade of Berlin, people were totally disconnected and could not have any type of contact with the outer world.

2.- What was the reaction of the western European allies to that decision?

The United States and Great Britain would not allow the Soviet Union to spread its influence by cutting Americans off from friendly peoples and territories. That was mainly the goal when they decided to start the Berlin airlift.

That is why on June 26, 1948, Great Britain and the United States started to send help and supplies to Berlin using airplanes. President Harry S. Truman wanted to avoid a direct confrontation with Russia or the possibility of another war in the region, that is why he opted for help by air.

3.- How everything ended after almost one year of the blockade?

In May 1949, the USSR lifted the blockade. It was clear to Stalin that his blockade has failed.

Which phenomenon occurs when the Sun crosses the plane of Earth’s equator
Vika [28.1K]
The sun appears to cross the plane of Earth's equator
when it reaches either one of the "equinox" points in the sky. 

At those times, the lengths of day and night are nominally equal
everywhere (except at the poles), and the occasions are marked
as the beginning of Spring and Autumn.
