Science Mysteries: How Many Species Are There?

You might think that after 200 years, the scientists who find, name, and describe Earth's species would be close to finished. But taxonomists, as organized as they may be, have no idea how many species Earth has. Nor can they even provide an educated guess. Although reporting over 16,000 new species every year, taxonomists still cannot predict how many more are undiscovered.

In total, taxonomists have categorized and listed 1.2 million species on Earth. At this point, you would think scientists should be able to use the information they have gathered to make good predictions about how many species an ecosystem can support. This would help them make better predictions about how many species are left to identify. So far, however, the guesses seem to vary so greatly that it seems there is no good theory for making a prediction.

One of the main problems is that most of the places that seem to have a lot of diverse species are in places that are hard to get to. One such place is the ocean, where scientists believe some 80 percent of Earth's creatures are hiding at depths too deep for us to study. In addition, many of the planet's most diverse areas are in remote places with few taxonomists.

Despite all the unknowns, scientists have agreed that there are between five and 15 million species left to discover on Earth. This is a huge range, but whether it's five or 15, taxonomists clearly still have a lot of work to do. And who knows, there may yet be a dragon or a Loch Ness monster left to discover.

Which of the following best paraphrases the paragraph in bold?

One problem is that lots of places that may have lots of diverse species are hard to get to. Take the ocean, where taxonomists believe 80 percent of species are hiding. Also, the planet has diverse areas with remote places.
Scientists have difficulty finding and identifying over three-quarters of the world's species due to their habitats being out of human reach. Due to deep oceans and isolated locations, many species will go undiscovered.
The depth of the ocean makes it tough to see things.
There is an issue with locating a large number of species because of the ocean.

Answers

Answer 1

Scientists have difficulty finding and identifying over three-quarters of the world's species due to their habitats being out of human reach. Due to deep oceans and isolated locations, many species will go undiscovered. Option B

What is the best paraphrase?

Generally, The main issue with determining the number of species on Earth is that many of the places that likely have a high diversity of species are difficult to access, such as the deep ocean and remote areas. This makes it challenging for scientists to find and identify a large portion of the world's species.

The best paraphrase is one that accurately conveys the same meaning as the original text, but uses different words and phrases. It should be grammatically correct and maintain the tone and style of the original.

Additionally, a good paraphrase should not plagiarize the original text.

What are three things you know about Japanese internment camps?.

Answers

Answer:

During World War II, the United States government forcibly interned around 120,000 Japanese-Americans in internment camps.

The internment was motivated by racial prejudice and fear of espionage, rather than actual evidence of disloyalty.

The internment camps were located in isolated, often remote areas, and were characterized by poor living conditions, lack of privacy, and limited access to education and job opportunities.

The internment was challenged in court and in 1988, the U.S. government formally apologized and provided reparations to surviving internees and their families.

The internment of Japanese-Americans is widely considered to be one of the most egregious violations of civil liberties in American history.

Q. What enabled the economy of the Mughal Empire to flourish under the reign of Akbar, the third Mughal Emperor?a. cooperation with Christiansb. an improved system of taxationc. an emphasis on gold production

Answers

Between its establishment in 1526 and its demise in 1857, the Mughal Empire ruled over a large portion of India. During its reign, the Mughal Empire was a global center of trade and technology.

Many historians argue that India was a formidable rival to Europe and India until the 1700s. However, the decline of the Mughal Empire, and the subsequent colonization of India by Britain, plunged India into a century of poverty, from which it is still struggling. Babur, a Central Asian prince who defeated the Delhi Sultanate, the Mughal Empire's predecessor, established the Mughal Dynasty. Humayun, Babur's son, succeeded him to the throne. Humayun lost control of a large portion of the empire before regaining control years later. Babur and his ancestors were Muslims. When they conquered India, they ruled over a Hindu majority. While Islam was the official religion of the Mughal Empire, Emperor Akbar the son of Humayun created a new syncretic religion that combined Islam and other religions in order to cement the people's loyalty. The Mughal Empire expanded to control the entire northern half of India during his reign, ushering in a golden age of prosperity.
