Google Questions and Answers

Google Questions and Answers is a free knowledge market offered by Google that allows users to collaboratively find answers to their questions (also referred as Google Knowledge Search). It was launched in June 28, 2007 and replaces the fee-based Google Answers service, discontinued on December 1, 2006. Google had chosen Russia as the first country to launch this new service.

Technologically, Google service most closely resembles analogous services by mail.ru, Naver and Yahoo!. It is pseudonymous: the nicknames of the authors of questions and answers are shown right next to their contributed content. Google uses question tagging to help users find relevant questions.

As most services of this kind, Google provides an incentivesystem to motivate people to answer questions. It is based on assigning points for actions and a system of levels loosely based on the Russian system of academic degrees. An interesting feature of the incentive system is that Google's reward for visiting is higher than for posting an answer.

On August 20, 2007, Google and Tianya, a Chinese community website, launched a free Q&A service entitled "Tianya Answers".

Predecessor

Google Answers predecessor was also called Google Questions and Answers, which was launched in August 2001. The previous service had Google staffers e-mailing responses to questions for a flat $3 fee. It was up and functional for about a day. The demand may have overwhelmed their resources.

Question:TRUE/FALSE: 1. After cell division, each new cell will contain the same genetic information as the original cell. 2. The cell cycle has checkpoints that act to inhibit uncontrolled cell divison. 3. Spindles move chromosomes during cell division. 4. During telophase, a nuclear envelope usually surrounds each new set of chromosomes. 5. Chromatids separate from eachother during telophase. 6. In plant cells, cytokinesis results in the formation of a cell plate in the center of a dividing cell. 7. Nutrients are needed by the body for repair and maintenence. 8. In the first stage of digestion, proteins are broken down by pepsins in the stomach. 9. Almost all lipids are broken down in the small intestine. 10. The liver stores fats-soluble nutrients and regulates the levels of food molecules in the blood. 11. The skin can be considered an excretory organ. 12. The kidneys filter out toxins, urea, water, and mineral salts from the blood. 13. The first stage or urine formation is called reabsorption. 14. Dialysis is a permanent solution to kidney faliure. 15. Atoms have a positive charge. 16. An element is made up of more than one kind of atom. 17. An atom with more electrons than protons have a positive charge. Thanks guys!

Answers:TOO MANY QUESTIONS 1. true except for the formation of sex cells 2. 3. 4. 5. 6. 7. true 8.false, digestion begins in the mouth 9.true 10.true 11.true 12.true 13 14. false, temporary 15 false, no charge 16.false, one kind 17.false, it is a negative ion, not atom

Question:This is the last question that i have in my biology review for my soon to be final that is coming up soon. I got really stuck on this question, and it is the last question i have! it sucks. so i am asking all you smarties for your help to answer this question for me. But please remember that i am only in 10th grade normal biology (my biology book is BSCS biology: A Human Approach second edition, if that helps at all). Please don't make your answer too 'out of my grade level' please. Please Please help me. I will pick the best answer, and give you lots of points... Please help, and thank you all for trying. Give me as many answers people, i don't care if someone else already answered, you should answer as well... please. Thank you all. please make your answer not too long. No more than around 6 sentences would be nice. and please have your answer only incluse, if possible, the 3 systems i said.

Answers:Most homeostatic regulation is controlled by the release of hormones (endocrine system) into the bloodstream (circulatory). However, other regulatory processes rely on simple diffusion to maintain a balance. Homeostatic regulation extends far beyond the control of temperature (this would a combination of.the circulatory system and the skeletal muscle system) All animals also regulate their blood glucose, as well as the concentration of their blood (the circulatory, excretory, and endocrine systems all work together to accomplish this). Mammals regulate their blood glucose with insulin and glucagon. The human body maintains glucose levels constant most of the day, even after a 24-hour fast. Even during long periods of fasting, glucose levels are reduced only very slightly. Insulin, secreted by the beta cells of the pancreas, transports glucose to the body's cells, lowering blood glucose levels. Insulin helps to prevent hyperglycemia. When insulin is deficient or cells become resistant to it, diabetes occurs. Glucagon, secreted by the alpha cells of the pancreas, helps the body utilise stored glycogen or convert non-carbohydrate carbon sources to glucose via gluconeogenesis, thus preventing hypoglycemia. The kidneys are used to remove excess water and ions from the blood. These are then expelled as urine. The kidneys perform a vital role in homeostatic regulation in mammals, removing excess water, salt, and urea from the blood. These are the body's main waste products. Sleep timing depends upon a balance between homeostatic sleep propensity, the need for sleep as a function of the amount of time elapsed since the last adequate sleep episode, and circadian rhythms that determine the ideal timing of a correctly structured and restorative sleep episode The endocrine system is a system of glands, each of which secretes a type of hormone to regulate the body. The field of study that deals with disorders of endocrine glands is endocrinology, a branch of the wider field of internal medicine. The endocrine system is an information signal system much like the nervous system. Hormones regulate many functions of an organism, including mood, growth and development, tissue function, and metabolism. The circulatory system is an organ system that passes nutrients (such as amino acids and electrolytes), gases, hormones, blood cells, etc. to and from cells in the body to help fight diseases and help stabilize body temperature and pH to maintain homeostasis. This system may be seen strictly as a blood distribution network, but some consider the circulatory system as composed of the cardiovascular system, which distributes blood, and the lymphatic system, which distributes lymph. While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system. The excretory system is a biological system that removes excess, unnecessary or dangerous materials from an organism. It is responsible for the elimination of oxygen waste products of metabolism as well as other nitrogeneous materials. Since the normal operation of most biological systems creates waste, the excretory system is not necessarily distinct from other systems. Instead, it often represents the various excretory processes of several different systems The skin is another part of the excretory system: it releases sweat, which helps cool the body and regulate the concentration of salt. The salt helps the water evaporate, cooling off the skin. The liver is an organ of the digestive system. It also helps in excreting wastes from the body in a variety of processes. Laboratory analysis reveals a high concentration of a small organelle called a peroxisome, responsible for breakdown of several toxic substances. It also takes in nitrogenous wastes and converts them to urea to reduce their toxicity. In anatomy, the urinary bladder is the organ that collects urine excreted by the kidneys prior to disposal by urination. A hollow muscular, and distensible (or elastic) organ, the bladder sits on the pelvic floor. Urine enters the bladder via the ureters and exits via the urethra.

Question:thank you to all that answer. all sources are appreciated.
