Natural Sources

Question: WhSome nitrogen entering the Mississippi River is from natural sources, but human actat would you like to ask? Some nitrogen entering the Mississippi River is from natural sources, but human activities are increasing the amount of nitrogen entering the river. What are the sources of nitrogen from human activities?

Answer: From fertilizers that get washed into the river from runoff, rains a.

Question: Natural sources of CO2 emit approximately 300 Gigatons of CO2 each year. Human activities are responsible for? Natural sources of CO2 emit approximately 300 Gigatons of CO2 each year. Human activities are responsible for about 6 Gigatons, or a mere 2% of that total. Measurements from a global network of surface stations over the past 40 years indicate an average annual increase of CO2 in the atmosphere of about 1%. Is this true? And if it is true, how can man be blamed for Global Warming?

Answer: You're either being completely dishonest by ignoring the fact that nature also absorbs 300 Gt, which completely cancels out its emission, or you're just too dumb to hold more than one idea in your mind at the same time. And it's not 300 anyway, it's more like 210. 90 from oceans, 120 from plants and soils. In, and out. Steady state. (Actually slightly more going in at the moment due to anthropogenic emissions). http://www.nasa.gov/centers/langley/images/content/174212main_rn_berrien2.jpg Not to mention there are several very solid reasons that we can know that the rise in CO2 emissions are anthropogenic, such as the isotopic signature, declining O2 levels, emissions estimates, etc.

Question: How will human live when all the sources of natural for energy used up? As we know the natural source for energy like oil, mine will be used up sooner or later. While almost all aspect of our life need them. Will we come back to time when there's no cars, television?

Answer: we would hav to search for other forms of energy like solar, wind, nuclear, geothermal, tidal etc

Question: I used Raw Thyroid by Natural Sources when I actually have a normal thyroid? SCARED? I used the pill Raw Thyroid, by Natural Sources when I actually have a normal thyroid. I guess for the sake of weight loss, I convinced myself i could be hypo, but I know im not... I just took one pill today. But, I am scared that even taking this one pill could screw my thyroid hormones.... Im so scared. I can't believe i became so damn stupid. Help please!

Answer: Stop immediately! The last thing you want to do is to disrupt a normal functioning thyroid. Never take any supplement without thoroughly researching first.

Question: What are some natural sources of Phenethylamine (PEA)? Phenethylamine (C8H11N) , sometimes known as PEA is supposedly found in several different foods. From Wikipedia: "Phenethylamine is a natural compound biosynthesized from the amino acid phenylalanine by enzymatic decarboxylation. It is also found in many foods such as chocolate, especially after microbial fermentation. It has been suggested that phenethylamine from food may have psychoactive effects in sufficient quantities. However, it is quickly metabolized by the enzyme MAO-B, preventing significant concentrations from reaching the brain." The only natural sources of PEA that I know of are chocolate, cheese, salami, and soy sauce. It would be a big help if I could find out any others you know about. This is for a chemistry project, and I need to bring at least 3 "physical examples". I can easily bring a chocolate bar, but I'd like something better than cheese, salami, or soy sauce for the other two. Thanks in advance! Kelsey @ Disco Stu: I'm not sure what you're trying to say. I'm a sophomore in high school and in chemistry class we're doing projects on different compounds. Mine is phenethylamine, and as part of my project (make a model, etc.) I have to show some examples (things it occurs in etc.). Phenethylamine is in chocolate, so I'm bringing a chocolate bar, but I need two more.

Answer: Certain cacti contain mescaline a natural source of phenethylamine. Tea made from the seeds of the peyote cactus flower contain mescaline. You could bring small black seeds. It's easy to bring to school. I added the web site.

Question: What are 2 natural sources that release carbon dioxide and methane? Also, what are 2 human sources that release methane?

Answer: Would this be a Global W.. issue? Forced to swallow by your teacher? - Earthquakes and increase in temperatures. Methanes are gassing as we speak in the arctic and oceanic regions. This without human intervention. And it's putting out more than our gas engines in a year. - When you Fart and when you disturbed an environment with known methane deposit ie: when you dig in the regions around arctic, tundra or even underground and ocean floor.

Question: is their a website with a list of "natural sources" of proteins? I am specifically looking for natural sources of Collagen. Thanks.

Answer: http://ezinearticles.com/?Natural-Sources-of-Collagen---How-to-Increase-the-Collagen-in-Your-Skin?&id=2019888 That's one website that is helpful. http://www.dry-skin-care-guide.com/collagen-natural-sources.html Here's another (:

Question: What are natural sources of Nitric Oxide? There was a nobel prize winner who has written a book suggesting that this would prevent heart disease --Dr. Louis Ignarro . What dietary sources are there?

Answer: Well, there's a slight misunderstanding with that... you may not want to ingest Nitric Oxide, but you want your body to produce more of it. When your body produces more Nitric Oxide, your circulation increases, which is probably why he was saying it would prevent heart disease (minimizing circulation issues to keep blood flowing). The major nutrients that help produce Nitric Oxide are L-Arginine and L-Citrulline (two Amino Acids), plus I've read that Korean Red Ginseng can help a little, too. Good luck and I hope I helped!

Question: How can i make my teeth whiter by using natural sources? is there any way i can make my teeth look more whiter? i tried using lemon juice, it worked but it goes back to it natural colour, also baking soda, these are all great, but they don't last so long.Any ideas? tnx

Answer: Apple cider vinegar can be used for teeth whitening,simply use it has a gargle diluted in a glass of water or add a few drops to your toothbrush and top it with toothpaste and brush . More remedies and information regarding your teeth at http://useinfo-dentalcare.blogspot.com/

Question: Is daylight "white light?" If not, what natural sources contain white light? I am trying to research the color spectrum as it relates to bubbles and I keep finding references to white light, but no sources for it. I tried to research it on the Internet, but all I get is page after page of stuff about artifical light sources. Thanks!

Answer: It depends on how precise you need to be about 'white'. Broadly, it's any reasonably balanced spectral mix over the visible spectrum. Daylight is well balanced, less so at dawn or dusk. A bright incandescent bulb is good. A standard fluorescent bulb is not, it's 'cool' (low in red), but a 'daylight' is better, and a 'full spectrum' fluorescent is the most balanced fluorescent. A photographic floodlight is balanced but more expensive. A natural source besides sunlight is a hot fire.

Question: What are some natural sources of collagen protein; and, why is is collagen protein so important? Is it really better than other proteins? Can I get enough of it through proper diet? If so, what food are best?

Answer: Collagen protein is not better than other proteins. Collagen protein is manufactured in your body to repair tendons, cartilage, and other connective tissue. Eating regular whey protein will give your body what it needs to make collagen. you do not need to take collagen unless you are older say around 50-60 or you have tendonosis or tendinitis. Collagen protein is not better than other protein and i wouldn't suggest using it as a supplement. to get more info on it go to www.bodybuilding.com

Question: What are some natural sources of particles in the atmosphere? My niece just asked me and we learned this in 7th grade. I think I may have short term memory loss. :)

Answer: An air shower is an extensive (many kilometres wide) cascade of ionized particles and electromagnetic radiation produced in the atmosphere when a primary cosmic ray (i.e. one of extraterrestrial origin) enters the atmosphere. The term cascade means that the incident particle, which could be a proton, a nucleus, an electron, or (rarely) a positron strikes an atom in the air so as to produce many high energy ions (secondaries), which in turn create more, and so on. The original particle having arrived with high energy and hence velocity near the speed of light, the products of the collisions tend also to move generally downward, while to some extent spreading sidewise. The overall effect, when the energy of the primary is high enough, is to produce a widespread flash of light due to the Cherenkov effect, and to excitation of air molecules. This can be detected with arrays of mirrors and photocells. The actual arrival of the cascade of particles can also be detected in many cases, also generally with detectors based on the Cherenkov effect. Haze is traditionally an atmospheric phenomenon where dust, smoke and other dry particles obscure the clarity of the sky Excess kinetic energy from solar winds can impart sufficient energy into atmospheric particles accumulation of charged solar particles Ice inside a cloud Diesel particulate matter (DPM), sometimes also called diesel exhaust particles Instead, they interact with the nuclei of atmospheric particles and cause a cascade of particles, known as an air shower This high energy radiation is absorbed by atmospheric particles, raising them to excited states and knocking electron s free in the ... aerosol particles , and solar radiation Aerosols are characterized by a particle size distribution function (PSD). Cutans are the modification of the soil texture , or soil structure , at natural surfaces (particle, pore, or ped) in soil materials

Question: What foods have natural sources of oestregen? Sorry this ended up in the vegan category... but I am talking foods in general.

Answer: I assure you, no food will have an oestrogen dose strong enough to support the transition you have in mind. There are offers on the internet. It would cost you some amount of money but will not really help to get female breasts or feminine curves or to stop your facial hair. If you are old enough, hopefully with the support of your parents, you may start hormone treatment. The earlier you can start it, the better results it will have. However, you will have to see an understanding physician. Much depends on whether you really feel transsexual, or if you are just a crossdresser, ready to explore your inner femininity by living it temporarily, part-time.

Question: What are four natural sources of phospates in a freshwater community?

Answer: In algae, in the silt, in the sedimentary rockbeds, and possibly in underwater vents.

Question: How many different natural sources of the rainbow are there?

Answer: pretty much anytime you have light going through a vapor, you get a rainbow. This is due to the prismatic nature of water droplets in the air.
