What is the applications of carbon isotopes?
The main ones are using c14. Radiocarbon dating gives acurate dating of historic and prehistoric organic materials. Also, c14 is used to "tag" carbon compounds to track how different sources of carbon are used in molecular biology/biochemistry. Additionally, c3 and c4 plants (this difference is in the regulation of photosynthesis) take in carbon isotopes at different rates. A c4 plant (like corn) will use c13 as readily as c12. However, c3 plants will not use c13 as readily as c12. This means that the ratio of c12 to c13 is different in c3 plants then in c4 plants. More importantly, the ratios are kept through tropic levels: when an animal uses carbon from a c4 plant, the ratio of c12 to c13 will be the same as in the plant. The use: we (humans in general) can analyze the ratio of c12 to c13 in animals, showing if they consume mostly c3 or c4 plants. This means that we can track carbon through a food chain or see if an historic tribe consumed more land based food (more likely c4) or sea food (completely c3). The studies that show that people from the US are 90% corn? Corn is the most common c4 food/carbon source today, and this type of study finds that people in the US have a c12 to c13 ratio that corresponds to 90% of our food to be derived from c4 plants.
What 5 factors affect the rate of transpirationfor a plant?
Photosynthesis is the conversion of light energy to chemical energy; the production of carbohydrates from carbon dioxide and water in the presence of chlorophyll by using light energy. In addition to plants providing energy conversion, food manufacture, and oxygen production (through photosynthesis) plants offer us food products, medicines, clothing, shade to mention just a few. Besides plants are the only living organism capable of manufacturing their own food. Rate of the process varies with the light intensity, temperature, and concentration of carbon dioxide in the plant's atmosphere.
What is the main ingrediant to c4 explosives?
C-4 (composition 4) is one of the popular plastic explosive(explosive chemical mix with plastic binder). It has 2 important advantages:The explosive material which coated with plastic binder will make it less sensitive to heat and shock. Since it is stabilized, it is relatively safe to handle C-4. Only detonator or blasting cap can trigger the reaction. Lighting the C-4 with a match will just make it burn slowly, like a piece of wood. (In Vietnam, soldiers actually burn C-4 as an improvised cooking fire.) Even shooting the explosive with rifle won't trigger the reaction.C-4 material is highly flexible. It can be molded into different shapes to change the direction of the explosion.Explosive material in C-4 is cyclotrimethylene-trinitramine (royal demolition explosive / RDX). Cyclotrimethylene-trinitramine was first prepared in 1899 from nitric acid and methenamine by Henning. The flow chart below (Please refer to reference below) shows the synthesis method uses methenamine (hexamethylenetetramine).Besides the method above, cyclotrimethylene-trinitramine can also be synthesized from formaldehyde, ammonium nitrate and acetic anhydride. (Method developed by Ross and Schiessler' in 1940's)Normally, C-4 is made up of explosives, plastic binder, plasticizer and, usually, marker or taggant chemicals such as 2,3-dimethyl-2,3-dinitrobutane (DMDNB) to help detect the explosive and identify its source. In 2004, Kenneth E. Lee discovered a reformulation of composition C-4 explosive for superior energetic performance and flexibility. (US Patent: 6887324)Reference:How C4 explosive is made.

What is the fluid capacity for a c4 transmission?
Ford C4 Automatic Transmission refill capacity (approx): * C4 / 302 c.i. = 9 US quarts * C4 / 351 c.i. = 10.25 US quarts * C6 = 12.5 US quarts * FMX = 11.0 US quarts Use Ford "Type F" fluid Source: Haynes Ford V8 Mustang 1964 1/2 thru 1973 Automotive Repair Manual
Who invented C4 bomb?
No single individual or even group of individuals invented C4, it evolved in a series of changes and improvements due to changing military requirements and operational conditions over time.C4 was a reformulation of C3 which was a reformulation of C2 which was a reformulation of C1 which was developed during World War 2 as an improvement on the Composition B and Composition A explosives that the US military was then using. Note: C1 through C4 are Composition C explosives. All three (Composition A, Composition B, and Composition C) explosives have numbered revisions, C4 is just the 4th revision of the basic Composition C formula.The original US Composition A formula was adapted from a British formula for plastique explosive, which was then being supplied to the French resistance (thus the spelling "plastique").
How many quarts of oil in c4 transmission?
It is important to know the oil capacity of a given transmission. For a C4 Transmission its oil capacity is 9 US quarts.
What retailers sell a nap mat?
Toys R Us is the largest distributor of Nap Mats. They come in a variety of colors and sizes all at a great price. They come with rave reviews from many satisfied customers.
Do guys like it when a girl takes a nap on their shoulders?
We only like it if you let us sleep on your boob in return.
Should schools have mandatory nap time?
I would say yes. Why do the teachers think us students are always so sleepy? Yes.hell ya
Can you own c4?
In the US, it is possible to obtain a destructive device permit, although some states expressly prohibit the transfer of any categorised by the BATFE as a destructive device to civilians.
At what point did young Mexican soldiers make a heroic stand?
When defending the Chapultepec military academy (at Mexico City) from US occupation forces on September 13th, 1847. They are called the "Niños Heroes de Chapultepec" (Child Heroes or Heroic Cadets of Chapultepec).http://en.wikipedia.org/wiki/Ni%C3%B1os_H%C3%A9roes
Can a residential carpet cleaning service restore the look and lift the nap of a matted carpet?
We just moved into a new place with a basement carpet that is an unusual color but it is a little matted down. Would a residential carpet cleaning service be able to lift the nap for us, and make it look fresh and vibrant?
What is Black Mustard Seeds?
The black mustard plant (Brassica nigra) is native to Asia and southern Europe, but has been transplanted and cultivated elsewhere. Its seeds are used as a spice (rai) in India, and the plant is grown as a vegetable in Ethiopia. In the US, the plants can be found growing as wildflowers in northern and central Illinois.
Where do Bahai's pray?
Most usually in their own homes, because we pray daily. There are devotional meetings where Bahais and anyone else who wants to join us pray, read scriptures, meditate and (with a bit of luck) sing together. These are usually in people's homes but there is sometimes a local Bahai centre. There are also a few specially dedicated Houses of Worship. There's an article on them in wikipedia:http://en.wikipedia.org/wiki/Bah%C3%A1%27%C3%AD_House_of_Worship
