1 answer:

It isn't exactly known who discovered it first, but the earliest claim of earth being round rather than flat was posed by Pythagoras sometime around 500 B.C. He argued that if the moon was round the Earth should be as well.

After that, his claim was proven true by a man named Anaxagoras at around 500-430 B.C when he brought up solar and lunar eclipses. The shape of Earth's shadow on the moon was also used as evidence that the Earth was round.

And finally, in 350 B.C the great Aristotle declared that the Earth was a sphere based on constellations you can see if you travel farther from the equator. Over the next hundred or so years, Aristarchus and Eratosthenes actually measured the size of the earth.

We all use maps, whether they are atlases, street maps, or simple maps we draw for our friends. Describe a map you use regularly

bogdanovich [222]

I have recently moved to a new city, so a map that I use often is a map of the city that includes all important touristic attractions. The map highlights items such as museums, art galleries, restaurants, coffee shops, shopping malls, parks, historic landmarks and other elements of cultural interest.

This map allows me to find locations, but it also includes extra information, such as the nature of each location. The map fits in the category of special interest, as it addresses a need (tourism) that is not usually included in most standard maps.

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!
