Answer:
Mars
Explanation:
At present there are around 540 extrasolar known planets. These are distant planets so not a lot is known about them, but there are some basic things that provide some basic information about them. It seems that the majority of them are planets that resemble Jupiter, being large and gaseous planets. It is very rare that a planet resembles Mars, in fact it is the rarest type of planets among the known planets so far. Even the planets that do share some characteristics with Mars, they also have characteristics that make them different, especially their size and distance from their star. Mars type of planets are very rare because of what Mars have actually become. The planet is assumed to have been similar to Earth, but its core has stopped its activity, resulting in no magnetism, and no volcanic activity. Also, the atmosphere of this planet is very thin, the temperatures vary greatly throughout the day, and its surface is covered with thick layers of dust and craters.
Answer:
1 ) buprenorphine treatment
2) Convenience goods and services
3) furniture
4) electrical goods
5) hairdressing,
respectively
Explanation:
Threshold is the minimum population and range is the maximum distance needed to sustain a good. As such, it'd make sense for buprenorphine treatments (a rare service) to have a low threshold since not too many people will be buying it, but it's still sustainable since it's expensive.
"Medium" is a loose definition so I would say any convenience good or service would be good for this one.
Furniture would have a large threshold because a lot of people are moving and in need of furniture.
People are willing to travel great distances to get electrical goods because they're specialized goods and you can't just find them anywhere, thus, it has a large range.
Things like hairdressing aren't worth traveling great distances to receive so they have a small range.
Red Sea Reef, since a reef is a productive and diverse organism with different species of coral.
Answer:
the North Pole
Explanation:
The point furthest north on Earth is the North Pole. The point opposite to the North Pole is the southernmost point, the South Pole. The North Pole is located in the central part of the Arctic Sea. These points are very important as the parallel and meridians are orientated in accordance to them, with every meridian passing through them, while the prime parallel, the Equator is set right in the middle between the two.
