Any GOOD SCIENCE FAIR PROJECT IDEAS?!?!?!?!?!?
I know this type of question doesn't get many answers, but anyone who crosses this and reads this, PLEASE suggest something, and make sure it isn't a dumb one... it has to be one that almost 90% of people wouldn't know what would happen. In other words, no volcanoes and junk with baking soda... or in other words, just don't, and i repeat DON'T, put plain old classics...
What's the difference between a concept and a principle?
First of all a principle is a concept it is a type of concept. A concept is an idea about something, and the value of using the word “concept” is to indicate that you are thinking about something in particular that you can probably name. A concept also usually is meant to represent an initial definition or a special description of something.A principle is ordinarily meant to represent a special relationship or rule that is required or expected to be in effect, with the potential to be also in control. Because “definitions” are used to rule or control recognition, principles often point out definitions that are most important to doing something or understanding something.Since both concepts and principles may involve definitions, it is helpful to see the difference in how definitions are important when using a concept instead of a principle.In general, use a concept to distinguish what someone should pay attention to. Use a principle to emphasize why something should be used a certain way or be evaluated a certain way.
The principle that bonds in DNA can only form between adenine and thymine and between guanine and cytosine is?
I need help with my science study guide and this is one of the questions The principle that bonds in DNA can only form between adenine and thymine and between guanine and cytosine is ___________________________ a. translation b. transcription c. replication d. base pairing When you answers this question can you also explain why thank you.
What is the difference between cultural evolution and biological evolution?
They are the two best examples of what is known as Universal Darwinism.Biological evolution was identified first, primarily by Darwin. But as the process of biological evolution became understood as an algorithm operating through the ability of RNA & DNA to replicate, people began to realize that the algorithm might also be able to run with other kinds of “replicators”.In The Selfish Gene, Richard Dawkins discussed cultural evolution and coined the term meme for the unit of replication analogous to genes. Dawkins didn’t pursue this idea in any real sense, but other researchers have, some calling it memetics. The field has kind of sputtered, and many deride it, but there are some brilliant minds who take it quite seriously. I’m thoroughly convinced that it is true, but this has a lot to do with the fact that I am a software engineer with a lot of experience in algorithmic thinking, along with some experience in linguistics, and I have been interested in consciousness and intelligence (both natural and artificial) my whole life.The philosopher Daniel Dennett has written a lot about evolution, both biological and cultural. His recent book From Bacteria to Bach and Back is well worth reading.I think the most interesting take on the evolution of culture that I have seen is that made by the theoretical physicist David Deutsch in his book The Beginning of Infinity, in the chapter titled The Evolution of Culture. There he makes what I think is a very compelling argument that the Enlightenment was due to a kind of phase transition that took place in cultural evolution when critical thinking took hold. Highly recommended reading for anyone curious about cultural evolution.The biggest difference between biological and cultural evolution comes from the fact that genes and memes are very different kinds of replicators. A gene must have a very specific physical manifestation (sequence of codons) and the replication of genes only happens when organisms reproduce. Memes are much more fluid. A meme can be transferred from one mind to another in a few moments of conversation, but when this happens the meme is typically changed in subtle and even profound ways. Culture therefore evolves radically faster than biology.
Can I take biology in class 12 CBSE if I didn't take it in class 11?
As Uncle Sam says, YES, YOU CAN.Anyway, normally you cannot take the subject you don't have in XI, but in certain cases, to avoid undue hardship, Chairman of the board may allow the change of subject. But you should request before 30th of August. I have seen one such case, a friend of mine changed from bio to computer. He stated his medical condition, I don't remember what it was, backed by our principle. So have some good backing, and remember the time limit.
Can biology be reduced to physics?
There are two answers to this question. One is "yes", the other is "no".Yes, because all biological phenomena are also physical phenomena. That is, there is no "vital principle" or any other nonsensical formulation that separates biology from physics. It is all physics, all the way down.And "no", for the same reason. The terms "biology" and "physics" don't describe different, neatly separated domains of the natural world. They describe different areas of emphasis and different approaches to study, and most importantly, different types of explanations. We don't need to invoke quantum physics to understand the flow of information from DNA to RNA to protein, or the dynamics of natural selection. We can make useful predictions and satisfying observations about biology without resort to fundamental physical principles. The separation of knowledge and explanations into different domains is a useful intellectual shortcut. If you try to reduce biology to physics, you are no longer using that shortcut, and are no longer talking about biology.
What kind of macromolecule is nucleus made out of?
The nucleus has a membrane and contains the chromosomes which are made from DNA. deoxyribose nucleic acid.
What is the best textbook for structural biology?
For a basic and complete overview, I would suggest Cantor and Schimmel's three part series. These books have all the basic information anyone studying biophysics/biochemistry would need. : Biophysical Chemistry: Part I: The Conformation of Biological Macromolecules (Their Biophysical Chemistry; PT. 1): 9780716711889: Medicine & Health Science Books @ Amazon.comFor kinetics, I don't think there is a better book than Segel's enzyme kinetics. Enzyme Kinetics: Behavior and Analysis of Rapid Equilibrium and Steady-State Enzyme SystemsIf you would like a more biophysical perspective of molecular interactions, I would suggest Israelachvili's intermolecular and surface forces : Intermolecular and Surface Forces, Third Edition: Revised Third Edition: 9780123919274: Medicine & Health Science Books @ Amazon.com This book has three parts, the first part is purely focused on the physics behind molecular interactions, the second and third part is focused on surface interactions and lipid membranes. It is truly a fabulous book.
