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.
Answer 2

Answer:

the answer is A. Diverse

why are pygmies short

Answers

Answer:

There are a number of theories to explain why pygmies are so short. It has been proved that their height is hereditary, and is passed on from parents to children. It may have evolved because of the low ultraviolet light found in rainforests, where many pygmies live. This would mean that the pygmies would make less vitamin D in their skin.

Which line is the BEST example of the author creating tension?


Select one:

Then he remembered what followed that evening. It was decided that the young man should spend the years of his captivity under the strictest supervision in one of the lodges in the banker’s garden. It was agreed that for fifteen years he should not be free to cross the threshold of the lodge, to see human beings, to hear the human voice, or to receive letters and newspapers.

What was the object of that bet? What is the good of that man’s losing fifteen years of his life and my throwing away two million? Can it prove that the death penalty is better or worse than imprisonment for life? No, no. It was all nonsensical and meaningless. On my part it was the caprice of a pampered man, and on his part simple greed for money…

He was allowed to have a musical instrument and books, and was allowed to write letters, to drink wine, and to smoke. By the terms of the agreement, the only relations he could have with the outer world were by a little window made purposely for that object.

The agreement provided for every detail and every trifle that would make his imprisonment strictly solitary, and bound the young man to stay there exactly fifteen years, beginning from twelve o’clock of November 14, 1870, and ending at twelve o’clock of November 14, 1885.

How does an animal show curiosity?

Answers

Answer:

Animals can show curiosity by approaching the object of their curiosity cautiously, sniffing at it, pawing at it, and/or lightly scratching, biting, or pushing it. Usually, a curious animal starts out with a lot of caution when approaching an object, but once they determine it is not a threat, they will try to figure out its function. They will see how it tastes to determine if it's food. They will move it around to see it from different angles and determine if it's a toy. If it isn't food, isn't alive, and won't make a good toy, most animals lose interest quickly.

essay on early to bed early to rise make a man healthy and white​

Answers

Consider the following; Early to bed, early to rise, make a man healthy and wise. This statement is both physically and mentally correct. When going to bed early and waking up early, you get an opportunity to be refreshed throughout the day. Although being refreshed isn’t the only positive, you also have being motivated to do whatever you need to do throughout the day. Without enough sleep, you will be miserable unable to accomplish much. Now what does healthy and wise mean? Well, it makes you physically and mentally healthy. Sleep does affect your health. Wise men do wise things. Staying up late isn’t very wise. This whole statement ties into each other, and relies on each other.

Sorry if this isn’t correct I hope it helps though.

There many advantages of sleeping early and rising early. More rest equals more energy, plain and simple . If you get into the routine of rising early and retiring to bed early you are more likely to have a better sleeping pattern which leads to being more energetic throughout the day, helping you accomplish your goals and tasks in a faster and more productive manner.

If a person want to have rest he think of sleeping but if the same person need to work then he also need to get up and do his routine work. Studies show that an afternoon nap is great for adults, too. There's no need to feel lazy for indulging in daytime sleep. A short nap in the mid-afternoon can boost memory, improve job performance, lift your mood, make you more alert, and ease stress. Cozy up to these nap benefits.

Lack of sleep causes irritability, increased stress, forgetfulness, difficulties with learning and low motivation. Over time, it can contribute to anxiety and depression. Sleep time guidelines depend on a child's age. Every child is different, so take time to figure out what works best for your child.

At a more advanced level, sleep deprivation can over-stimulate parts of the brain and even lead to permanent brain damage, according to a report on sleep deprivation among students published by The Guardian. “This is because of the brain's 'neural plasticity' – which means its ability to adapt to new situations.

So now I would like to end here by requesting that I hope the ones who now know the disadvantages will try their best to do as told and wishing Best of Luck for the ones who already to this. May they achieve all their goals in their further life and be a successful citizen of their country.
