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 word from the third paragraph best describes the problem facing taxonomists?

Diverse
Ocean
Creatures
Remote

Answers

Answer 1
I would have to go with Diverse because the whole problem is that taxonomists the people that are the most educated for this topic can’t even comprehend how many species there are in this big green and blue planet that we call Earth. According to this article it’s talking about how many DIFFERENT species there are on earth and another word for different is DIVERSE.

Let each member of your family answer the questions below then from each member's answers, try to formulate a report that exhibits the guidelines discussed. a. How do you get to school/work? b. What is your favorite TV Program? c. Where do you normally have your lunch? d. When is your favorite past time? e. Why do like a person?

Answers

Answer and Explanation:

The car is the vehicle most used by all members of my family, whether they go to school or work. Not all family members own their own cars, but everyone who owns them is available to give rides to those who do not have a car or cannot drive. Nobody in the family is very attached to TV programs, but older members often watch the news regularly.

Currently everyone's lunches are being held at home, but in the past all lunches were held on the scale or work.

The reasons that make family members like a person vary, but in general we can inform that everyone likes polite, respectful people who respect each other's limits.

The external is Leamas’s struggle against Mundt; the internal conflict in his weariness if death.

The external is Leamas’s struggle against Control; the internal conflict is his weariness if Mundt.

Answers

Answer:

The second option is the right answer.

Explanation:

External conflict is characterized as a struggle between characters, or a struggle between a character and something physical and palpable. An example of this is the struggle between Leamas and Mundt.

An internal conflict, on the other hand, is a conflict that occurs within a character's mind, a conflict between thoughts, feelings and concepts that the character himself has. An example of this is the internal conflict that Leamas feels when he reflects on his tiredness and death.

Read the excerpt from "Pakistan's Malala." But what do you do when you're 11? You go to the playground and you play, so that's what they did. Some of the girls said they thought everything would work out. They'd be back, they said. Malala wanted to be hopeful, too. But before she left, she turned around and took one long look at the building. Malala was right about the edict and what it meant. After January 2009, she was forced to stay at home and read books, Ellick said. Eventually she was moved around the country where she attended ad-hoc schools. How did the setting of Malala's education change after the Taliban took over Swat Valley? She had to read at home or attend school in secret locations. She joined other children at the playground to read and study. She stopped trying to pursue an education in any way. She continued to attend the same school she had before.

After January 2009, she was forced to stay at home and read books, Ellick said. Eventually she was moved around the country where she attended ad-hoc schools.

Malala and the other girls were no longer allowed to attend school. To continue her education, Malala would read books at home and, later, would move around, attending classes in secret. Malala has become an example of courage and perseverance for the whole world after fighting for her rights. She was attacked by the Taliban, being shot. She survived, and has recently graduated from university.

Which sentence exemplifies the logical fallacy "authority"? Don't ask my friend to help you plan for the party; she has terrible taste in music. If we don't elect Mrs. Smith to the senate, we will definitely see a rise in taxes. My dentist doesn't believe in taking vitamins, so I don't take them either. We never had any crime until Mr. Jones was elected to office, so it's definitely his fault.

Answers

Answer: My dentist doesn't believe in taking vitamins, so I don't take them either.

Explanation:

The logical fallacy authority occurs when one uses the testimony of a particular person who is in the position of an authority even though the person in question isn't an expert in that particular field.

The sentence that exemplifies the logical fallacy "authority" is "My dentist doesn't believe in taking vitamins, so I don't take them either".

In this case, a dentist is an expert with the teeth and not an expert in the field with regards to the question. Therefore, this is a logical fallacy authority.

Angela wants to know how many families in her neighborhood plan to attend the parade. She puts all 120 of the neighborhood addresses in a hat and draws a random sample of 30 addresses. She then asks those families if they plan to attend the parade. She finds that 40% of the families plan to attend the parade. She claims that 40% of the neighborhood families would be expected to attend the parade. Is this a valid inference?

Yes, this is a valid inference because the 30 families speak for the whole neighborhood
Yes, this is a valid inference because she took a random sample of the neighborhood
No, this is not a valid inference because she did not take a random sample of the neighborhood
No, this is not a valid inference because she asked only 30 families

Answers

Answer:

Yes, this is a valid inference because she took a random sample of the neighborhood.

Answer:

B. Yes, this is a valid inference because she took a random sample of the neighborhood

Explanation:

A. Yes, this is a valid inference because the 30 families speak for the whole neighborhood - This is not correct because the families she asked do not speak for the whole neighborhood

C. No, this is not a valid inference because she did not take a random sample of the neighborhood - She did take random samples so this is not the answer "She puts all 120 of the neighborhood addresses in a hat and draws a random sample of 30 addresses."

D. No, this is not a valid inference because she asked only 30 families - I don't believe she needs to asked the whole neighborhood or more people because she did a random pull

So, the correct answer is B.
