Q: do the bigger curling irons give you bigger waves/curls? I have skinny sort of curling iron and I can never create those large waves.: the bigger curling irons are only good for people with long hair, if you have shorter hair, the curl will just fall out. use the skinny curling iron. use flexible hair spray to hold it, and then separate the curls and it should give you that blake lively look

Q: Black, pink, or precious metals straightening iron?: I personally like the silver

Q: I have read men are not supposed to supplement with Iron. (like in vitiamins etc) because iron is accumulated and stored in Males unlike females who need it do to mensturation.Bottom like the cereals I like have Iron in them like Post Bannana Nut Crunch. Is this bad for me? ALso spinich has lots of Iron is that bad for men as well?: no its good. but soya is bad for male. it builds female hormones.

Q: iron and iron: Iron is a mineral. It is a metal. The inactive ingredients in iron tablets are made of the same kind of chemicals as vitamins.

Q: medicus 7 iron or medicus 5 iron? which would be more helpful and useful.: In my honest opinion, it doesn't really matter. When using a swing trainer, your not really focusing on the loft or distance of the ball. Medicus irons are mainly used to teach your muscles the correct way to swing so that it becomes almost second nature when you're using real irons. This is achieved by repitition. If you continue just to practice the correct swing, then you will greatly improve your shot. Aside from feet placement, an iron swing is an iron swing for most golfers. Buy whichever one you want, practice until it feels right, and you'll be hitting both your 5-iron and 7-iron better no matter which medicus iron you buy.

Q: what happens when you boil iron then it vaporizes then you breathe it in what happens?: iron boils at 2862 °C, 5182 °F so when you inhale it, you will have molten iron at 5000 °F condensing in your nose and lungs. I don't think that is good for you! .

Q: What does the existence of iron-rich rocks during the Precambrian indicate about the evolution of Earth‘s atmosphere?: the precambrian represents a VERY VERY large chunk of time. it is everything before about 540 million years ago. if earth is 4.6 billion years old, thats means the pC lasted about 4.1 billion years. there was not always abundant oxygen on earth. in fact, earth was very anoxic, and oxygen was a nasty, poisonous byproduct to the earliest entities of life. about 2 billion years ago, halfway through the pC, the first photosynthetic bacteria start pumping the O2 out into the ocean. iron in the seawater quickly reacted with any new oxygen to form that characteristic rust-colored iron oxide, Fe2O3. the iron minerals quickly fell out of suspension, causing the notorious banded iron formations (BIFS) however, since there was a limited amount of iron and an exponentially increasing amount of free oxygen, eventually that chemical sink was used up and O2 was able to accumulate. organisms at the time either had to adapt to being tolerant of oxygen, die off, or take refuge (e.g. the organisms that now live by deep ocean thermal vents). so, for your answer, we really only see iron-rich rocks during the later half of the precambrian. it documents a time where the oxygen produced was being locked up into iron-oxide minerals instead of accumulating in the ocean (and thus the atmosphere because of mixing). it was only once all the iron was oxidized that the O2 crisis set in and free oxygen began to accumulate.

Q: Iron absorption in achlorhydria?PPIs and H2RAs increase gastric pH by blocking acid secretions and making the overall gastric contents more alkaline. Subsequently an individual who ate foods rich in iron would not absorb that iron because the food sources need to be converted from ferric to it‘s ferrous formhaving said that.how would a person with achlorhydria alter iron salts like ferrous gluconate, fumurate, and sulfate?? Thanks!: It is true that iron absorption is decreased in achlorhydric states, but there are other factors affecting inorganic iron absorption, for example, the intestinal brush border cells also produce ferric reductase, which can convert the insoluble ferric iron to the ferrous form, especially in the duodenum where majority of the absorption occurs. In clinical practice, achlorhydric states and patients with iron deficiency anemia refractory to oral iron supplements are treated with Parenteral Iron supplements.there are I.M and I.V formulations available. So that's always the other option. Just read your additional details this is my understanding of the process. Dietary iron can be taken in two forms, Organic and Inorganic. Organic iron which is contained in heme, from animal meat sources etc are not subject to the above mechanisms. But in the case of inorganic iron, it needs to be made soluble first in order for absorption to take place. So the insoluble ferric form needs to be reduced to the soluble ferrous form this is where the gastric pH comes into picture. Reduction means addition of hydrogens (or removal of oxygen), so in a low gastric pH, there will be an excess of hydrogen ions, and that will help reduction of ferric to ferrous, thus aiding in absorption. This should be explained in detail in a Medical Physiology book like Guyton. Btw, there have been a lot of papers written investigating achlorhydria and iron absorption, try searching for medical journals.try searching for Omeprazole therapy and iron deficiency this was a highly researched topic because proton pump inhibitors are known to cause achlorhydria. If I remember correctly, none of them give a clear cut causal relationship to iron deficiency, although all suggest a correlation. Best Regards

Q: whats tye BEST and cheepest straightening iron?: you dont necessarily have to buy a straightener to get straght hair. good starighteners can be expensive, all you need is a hair dryer and a comb. heres how; 1) wash your hair thoroughly, and wring out the water. 2) dry your hair on high heat, starting from the very top of your head and going VERY SLOWLY and VERY CLOSE TO YOUR HAIR. 3) REMEMBER! you have to comb through your hair as you move the dryer so it stays straight. you'll get awesomely straight hair and its quick and easy good luck.
