This hub comprises 10 of the best biology questions I have been asked by my students during their biology lessons in the past year. Rhys Baker (author) from Peterborough, UK on May 12, 2012: @Robin: That's great! That is fantastic! If we stop suddenly, our eyes and other sense organs immediately send a signal to the brain that the body has stopped moving. It includes mammals, birds, reptiles, fish, frogs, clams, lobsters, insects, worms, and jelly-fish. High praise indeed :) I'm glad you found my hub interesting and engaging. These highly specialised cells exhibit a number of adaptations to help them do their job: It should be obvious that neurons do not work in isolation - many are needed to transmit a signal to its destination. I'm glad you enjoyed it Mmargie! Videosbym Answered: Nov 25, 2020. Gotta love it when the ads sync up that well :). When you swallow, the cold goes away and the same blood vessels rapidly dilate back to their original size. However,again, good hub and I like the brain freeze part! This can cause mutation, or even cancer, if the dose is high enough. The hollow woody tissue in plants that carries water and minerals from the roots to throughout the entire plant, 120+ Bar Trivia Questions and Answers – Best Pub Trivia Quiz, 50 Baby Shower Trivia Quiz Questions and Answers, History Trivia Questions – 300+ Questions and Answers, 50+ Football Trivia Questions with Answers. Also an anti-diarrheal. Food does not move down our digestive system by gravity - if that were the case, astronauts would not survive in space. I so agree with you - and not just science but all education, maybe even life itself! Fish don't 'breathe' underwater, but they still need to absorb oxygen and remove oxygen in a process known as gas exchange. In molecular biology, what term refers to the structure formed by double-stranded molecules of nucleic acids such as DNA? Biology Questions. The danger with x-rays is that they can knock electrons away from atoms, creating ions; this is why x-rays are called 'ionising radiation'. and Why does Helium Make your Voice go Funny? I love the ads which said, want to have a brainfreeze? The brain accepts both signals as true and so decides that the head is spinning, whilst the body is stationary. The more often a series or collection of neurons are caused to fire, the easier and easier it becomes for that same pattern to be repeated: this is the basis of learning. Are there nuclear reactions going on in our bodies? Available Formats. I try to teach my pupils that science is not so much about getting answers, but about asking questions. Candace Bacon from Far, far away on May 06, 2012: Biology has never been my favorite science subject, but you present it in an interesting and engaging way. The large calcium molecules that make up our skeleton block the path of x-rays. Ions are much more reactive than atoms and can shoot about your body damaging important molecules like DNA. Wonderful!! The explanation of each body problems is good. Great questions and smartly answered! Mmargie1966 from Gainesville, GA on May 07, 2012: @cocopreme: Wow!

Some great questions really well answered in a way that makes even the complex science easy to understand. I think people will enjoy learning the answers to these questions. Brilliant. What is the human body's largest organ? This is awesome and very interesting. When this fluid moves a signal is sent to the brain giving information about direction of movement. Thanks for sharing this. What is the most powerful muscle of the human body? Thanks to all for the great comments - I'm glad you enjoyed it. Lastly, these agents you mentioned treat nociceptive pain, and are not mainstays of neuropathic pain. There are two main types of painkillers that are commonly used: the 'aspirin medicines' and the 'narcotic medicines.'. Rhys Baker (author) from Peterborough, UK on May 06, 2012: @Melovy and Horatio: I'm very glad you enjoyed it :). These questions are hard to answer but, you sort in a scientific way. 61) What is an animal? This makes the gills extremely blood-rich giving a bright red colour. What is the human body's largest organ? Ana Maria Orantes from Miami Florida on September 15, 2014: Hello miss TSSscienties. A good Biology Tuition Teacher From Smiletutor is also a good way to enhance the knowledge base of the school children. Biology is a wondrous science that inspires us to discover more about the world around us. Rhys Baker (author) from Peterborough, UK on May 07, 2012: @TDAPharm: I'm glad you enjoyed the hub. Instead, muscle contractions in the gut wall called peristalsis both churn up the food and move it through the system. Secondly, many mammals fluff up their fur to appear larger and scarier when threatened or displaying during mating rituals. An x-ray is a form of high energy radiation with a wavelength about 10,000 times shorter than that of visible light. In addition, the pharmacology is different and as such only serves as an analgesic and antipyretic, while lacking the anti inflammatory properties of NSAIDs. Voted up, useful, interesting and shared. Just after the contraction we start to inhale which causes the glottis (a partioning wall between the windpipe and oesophagus) closes the windpipe, causing the 'hic' sound. Voted up and awesome. you've done great job. Did you know that falling out of bed kills 450 people a year in the US?, Ants claim another 30 lives and vending machines kill around 13 people; Safety is a relative term. Excellent info for kids of all ages.
