101 (one hundred [and] one) is the natural number following 100 and preceding 102. It is variously pronounced "one hundred and one" / "a hundred and one", "one hundred one" / "a hundred one", and "one oh one". As an ordinal number, 101st rather than 101th is the correct form. In mathematics 101 is the 26th prime number and a palindromic number (and so a palindromic prime). The next prime is 103, with which it makes a twin prime pair, making 101 a Chen prime. Because the period length of its reciprocal is unique among primes, 101 is a unique prime. 101 is an Eisenstein prime with no imaginary part and real part of the form 3n - 1. 101 is the sum of five consecutive primes (13 + 17 + 19 + 23 + 29). Given 101, the Mertens function returns 0. 101 is the fifth alternating factorial. 101 is a centered decagonal number. The smallest prime for which 2^p-1 has not been completely factored. For a 3-digit number in base 10, this number has a relatively simple divisibility test. The candidate number is split into groups of four, starting with the rightmost four, and added up to produce a 4-digit number. If this 4-digit number is of the form 1000a + 100b + 10a + b (where a and b are integers from 0 to 9), such as 3232 or 9797, or of the form 100b + b, such as 707 and 808, then the number is divisible by 101. This might not be as simple as the divisibility tests for numbers like 3 or 5, and it might not be terribly practical, but it is simpler than the divisibility tests for other 3-digit numbers. On the seven-segment display of a calculator, 101 is both a strobogrammatic prime and a dihedral prime. In science In mineralogy, a Miller index of 101 is a crystal face that crosses the horizontal axis (a) and 3d vertical axis (c) but does not cross the 2d vertical axis (b). In physics and chemistry, it is the atomic number of mendelevium, an actinide. In books According to Books in Print, more books are now published with a title that begins with '101' than '100'. They usually describe or discuss a list of items, such as 101 Ways to... or 101 Questions and Answers About... . This marketing tool is used to imply that the customer is given a little extra information beyond books that include only 100 items. Some books have taken this marketing scheme even further with titles that begin with '102', '103', or '1001'. The number is used in this context as a slang term when referring to "a 101 document" what is usually referred to as a statistical survey or overview of some topic. Room 101 is a torture chamber in the novel Nineteen Eighty-Four by George Orwell. In Other Fields 101 Ranch Oil Company Taipei 101, the tallest skyscraper in the world from 2004 to 2010. 101st kilometre, a condition of release from the Gulag in the Soviet Union.

The first course in a subject taught at a college or university in Australia, Canada, South Africa, or the United States. By extension, "Topic 101" is used generally to indicate the basics of any subject. The expression is also used in this non-academic sense in the UK. Used this way, it is always pronounced "one-oh-one". See Course number. For a new checking account in the US, the number of the first check. A term used to define the number of keys on a computer keyboard An emergency telephone number in Argentina, Belarus, Belgium, India, and Israel. 101 is the Single Non-Emergency Number (SNEN) in some parts of the UK, a telephone number used to call emergency services that are urgent but not emergencies. iCar 101 is a roadable aircraft design concept. 101 Dalmatians The Zastava 101 is a compact car by the former Yugoslav automaker.

Answers:The point of a practice exam is to check to see if you understand the content of the course! Having someone else provide the answers won't help you identify the areas in which your understanding of the information is weak! Use your text, the internet, or best, get a group of your classmates together to form a study group. A study group pools the minds and knowledge of the group to everyone's benefit!
Once you've identified where your weakness lies, you can focus your study efforts on those parts.

i think it was a test for us rather than a problem for u, wasn't it?
I was wondering if anyone knows of a really good site that teaches grade 11 bio. It should allow me to review concepts, terms ect. Give practice questions that I can work on, that sort of thing. Things to help me study for tests and my exam.
If anyone can link me to something like that, it would be awesome, thanks.

Intro To Phlebotomy 101 :By Beatriz Reyna. KNOP-TV News 2 The Medical profession relies heavily on those who work behind the scenes and that includes medical lab technicians. Its projected Health Care reform will add 40 million people to the health care roster that will only add to the demand for ML-T's. Beatriz Reyna shows us how North Platte Community College's MLT's hope to recruit potential students. When it comes to determining the health of a patient accuracy is vital. Eight students from Arcadia are learning just that through Mid-Plains Community College's Mobile Education Lab. Martin Steinbeck, NPPC Medical Lab Tech Program Dir., says, "A lot of students grow up thinking it's just about nursing and x-ray and they don't really know about us and so this is our way of making the career more visible." Students participated in a mock lab experiment where they tested for strep throat. Karalie Hickman, 12th Grade, says, "We had to do a test and it showed two pink lines if it was positive and one if you didn't." Panacea Fang, 12th Grade, says, "We can touch something we never did before and it lets me know more about the career instead of just knowing that it's a lab or biology or something like that." MLT's hope more students will enlist in their program. Steinbeck says, "If your parents or you have to pay for the education go to one of the community colleges. Then you can transfer to the University of Nebraska at Kearney or the University of Nebraska at Lincoln and rather at working at ...
