Sex Determination In Human Beings.

Sex Determination In Human Beings.Humans are Dioecious i.e. contain male and female gonads in different induviduals.Male Gonads produce sperms and the female gametes produce Ovum. Lower animals ad plants are usually Monoecious.The chromosomes which help in determination of the sex of the offspring are called the Allosomes or Sex Chromosomes. Whereas the vegtative chromosomes which are not helpful in sex are called the Autosomes.The method of sex determination in Human Beings is XY type, where in males, the Allosomes are XY type and in females the allosomes are XX type. Humans contain 46 chromosomes in the nucleus of the cell out of which, 44 are autosomes and other 2 are allosomes.On production of gametes, the no. of chromosomes is reduced to half , i.e. in the gametes there are 23 chromosomes. But the type of chromosomes is not same.In females, ova contains 22 autosomes and 1 X chromosome.In males, the sperm contains 22 autosomes as in ovum but the allosome can be either X or Y type, i.e. a sperm can contain either X or Y alloome.During fertilisation, if sperm with X allosome fuses with the ovum, then it results into formation of female offspring (XX) and if Y allosome of male fuses with the ovum, then it results to the formation of Male offspring (XY).Thus, Ovum has no role in "sex determination" but the sperm has the role of sex determination in human beings, i.e. if sperm has X allosome, offspring is female and if Y allosome is present, offspring if male.

Ginseng is chinese for man root - did you know that?

Ginseng is chinese for man root - did you know that?

The word ginseng is Chinese for man root, probably because the plant itself looks so much like a pair of legs. Ginseng has long been a very important herb in traditional Chinese medicine, and with the rise of New Age treatments in the West, it has become more popular here too. It is also known as Panax, the plants Greek name, which literally means cure-all (like panacea).The Chinese are not the only ones who made use of ginseng historically, however: the plant also grows in America, and Native Americans have eaten it for centuries, also using it as a medicine. As there is no way that the two groups could have been communicating with each other, either this is a huge co-incidence, or there must be some health benefits to ginseng.America and China are the worlds two largest producers of ginseng, but the Chinese believe that American ginseng is very different to their own. They say that their ginseng is Yang, while the Americans is Yin. As the Chinese traditionally believe that Yin and Yang must be balanced, there is a lot of demand for American ginseng.Ginseng can be eaten raw or prepared in various ways, but one of the most popular varieties is red ginseng. This is ginseng that has been heated up in the sun until it has gone red, and is then marinated in herbs. All sorts of extra health benefits are claimed for red ginseng, and many people also find that it tastes better.One thing you should be aware of if youre thinking of buying some ginseng is that many non-ginseng products are often labelled as ginseng: Siberian ginseng, for example, is not actually ginseng at all the same goes for Indian, Peruvian and Brazilian ginseng. Although they are labelled as ginseng in the hope that they will sell better, they are really completely different plants.

Stationary Exercise Bicycles

Stationary Exercise Bicycles

Bike riding is an excellent cardiovascular workout. Bike riding also provides an excellent low impact lower body workout. Many busy and active people find that the use of a stationary bike in their own home provides them the availability to get a work out whenever they want, regardless of time of day, or weather conditions. Some choose to purchase their bicycles with monitors that measure heart rate, fat burning zone and cardio zone to keep track of their fitness levels. Stationary exercise bicycles generally come in two different models, the standard upright and a recumbent. Standards mimic a conventional standard bicycle where you sit upright in the seat. However, just like on a conventional bicycle some find that the longer they sit on a bike the more aching they have in their lower back or groins. This can sometimes be corrected with a padded seat. A recumbent stationary bicycle is very well suited to those who suffer with chronic back pain or with lower back problems. You sit down into a very wide saddle seat with a well cushioned back. You sit and lean back into the seat on a recumbent bike, with your legs extended out in front of you. It's like sitting in your favorite reclining chair. Recumbent bikes produce less strain for your knees and lower back. Whatever your level of fitness remember to start slowly. You will want to warm up your muscles before you start pushing them. There is no better way to burn fat than an aerobic program. Stationary bike riding is a very good way to introduce interval training into your fitness program. If you're interested in more of a total body workout you can look into stationary bikes that have handlebars that you pull and push away from you as you pedal. If you choose a standard stationary bicycle you will want to make sure that you get an upper body workout using weight lifting or resistance training.

The Truth About Colon Cleansing

The Truth About Colon Cleansing

Do your research and you'll find all sorts of conflicting articles on what makes a healthy colon. You'll find a few websites that spreads uneducated negative thought about the need for colon cleansing, and you'll find they're sponsored by Joe Nobody. We'd have to advise you to ignore those "quaks" and listen instead to the real medical world. There are real reasons why the health care industry supports the idea of a clean and healthy bowel, although there are a variety of ways to achieve it.I'd recommend the one that's the safest and easiest to accomplish. I recommend using the colon cleanse that's only 5 days long instead of months and months. Use a "colon cleansing" product that's 100% natural and made by a company that uses 100% USA herbs and is 100% made in America. And more importantly, use the product that the leading master herbalists in the USA all recommend. The best one is called "Colon Cleansing Kit" and you can visit my websites to find out more information.The Colon Cleansing Kit The "colon cleanse" use is produced by Master Herbalist Martha Volchok. When Martha started to put together her Internal Cleansing program, to her, this was the ultimate formula. It was a chance for her to put everything she has ever done into one product. All the formulas balance each other and there are herbs to make it as smooth as possible. Martha spent eight months formulating the Internal Cleansing Kit. Eight months of constantly pondering and feeling: twelve formulas, over a hundred herbs, dosages, and the effect of each herb on someone's body. She drew from her experiences and the experience of others. Every resource she had available to her she pulled from, used as food for her intuition. As building blocks to create one master program.It was designed to show you your own body. To allow you to feel your self, knowing that for some of us ... this will be a first time doing a colon cleansing. For others it will be a re-birth, and for still others it will simply serve as a source of strength and inspiration to find themselves and their health. Martha gave all of herself to this kit. If you knew her at all, you'd know what this meant. Martha has an incredible innate sensitivity that permeates all she does. It allows her, I should say forces her, to feel the pain of any person she is around or of anyone who asks her for herbal help. It is this sensitivity coupled with an equally incredible appreciation for pain, that allows her to intuitively create a formula. Her appreciation for pain comes from a life that has been filled with numerous aliments and conditions. At age twelve she was run over by a horse and underwent operations for torn and lacerated liver and intestines. She has given birth to four children: one birthing broke her tailbone, and two led to uterine infections. At age 35 she suffered from extreme digestive pain and used raw food liquids and wheatgrass therapy for a year before recovering. In the last ten years she has been naturally cured of two life threatening diseases: Sarcoidosis in her lungs and, most recently, T-cell lymphoma in her blood. She is also extremely sensitive to artificial substances and modern medicine usually makes her sicker. In fact, she has had several root canals without novocaine or pain killers because of this sensitivity! She also knows what relief feels like and when she begins to make a formulas it is for this relief that she searches. Over the years she has created formulas for herself, her family, friends, workers, and complete strangers. Her formulas are always made for a real person, with a real discomfort.Martha put herself into the "Colon Cleansing Kit" ... she tested it herself, and I've tested it too. It's a simple, safe and healthy thing you can do for your own colon health in only five days. Like I said, there's absolutely no reason to do any colon cleanse that's longer than five to ten days. Happy colon health to you, and please visit my websites to learn more about colon detoxification cleansing.

Phage In The Food

Food is one of the core necessities of life and has often been hailed, along with music, as a universal language. No culture or civilization is without a means of preparing meals, instilling the same ingredients with a flavor unique to that region or group. Food has become so important for human survival and culture. But nothing can cause more worry and paranoia when food becomes tainted with infection. Sadly, there are several bacterial infections that you can get by eating contaminated food, though not all of them are frequent in appearance.One of the more common "bacterial infections" you can get from food would be e. coli. This particular bacteria is typically found in cattle, though it can also appear in smaller animals.Human can become infected if the food or water is tainted with cow feces, typically only needing microscopic amounts to have an effect. The common signs of e. coli infection are diarrhea mixed with blood and painful cramps in the abdomen. A complication known as hemolytic uremic syndrome can arise from the infection, which can manifest weeks after the first symptoms of the bacteria. This can cause problems such as anemia, damage to the kidneys which can lead to kidney failure, and profuse bleeding. In some cases, the bleeding can also be difficult to control.Salmonella is also indicated as being among the most common bacterial infections related to food consumption. This infection can occur due to a wide variety of animal-based foods, though the bacteria itself is frequently found in the intestines of mammals, reptiles, and birds. The bacteria is known to cause a specific illness known as salmonellosis. Symptoms of this condition include diarrhea, fever, and abdominal cramps. The condition is typically not life-threatening for the average person. However, for individuals whose health has already been compromised, or have weak immune systems, then are problems. Salmonella can easily spread to the bloodstream of those individuals, having potentially life-threatening side effects.Another infection that can come from food is campylobacter. Bacterial infections from this pathogen generally happen due to someone eating undercooked chicken. The primary source of the infection in humans comes from the juices that drip from raw chickens, such that poultry that has been undercooked has not been purged of the problem. Similar to salmonella, this bacteria causes fever, abdominal cramps, and diarrhea. Statistically speaking, it is considered to be the primary bacterial cause of diarrheal conditions around the world.There are, of course, other bacterial infections to be found in food. The above may be the most common examples, but they are not the only ones. Some contagions that are better transmitted by other means can also be transmitted by food. There are rare documented cases of strep throat being transmitted through food. Hepatitis A can also be transmitted through food, though this happens only in certain circumstances. Two particular parasites, the Giardia lamblia and the Crpytosporidia, can both find their way into the human body through contaminated food.Despite all the potential illnesses and bacterial infections that a person can end up having because of food, they can be avoided. Typically, all that is needed is proper preparation of the food. Making sure that the food is cooked properly and cleaned properly can stave off most bacteria. It is also advisable to check where the food came from, as meat from an area with a widespread infection usually carries pathogens.

Do you know the method of asbestos testing?

Asbestos testing is a very important process, since people know the dangers of this mineral (asbestos is a group of fibrous metamorphic minerals of the hydrous magnesium silicate variety). Most asbestos fibers are invisible to the human eye because their size.Asbestos testing is necessary, because you can't tell whether a material contains asbestos simply by looking at it, unless it is labeled. If in doubt, treat the material as if it contains asbestos or have it sampled and analyzed by a qualified professional. A professional should take samples for analysis, a professional knows what to look for, and because there may be an increased health risk if fibers are released.Asbestos testing should always be done by an expert.For asbestos testing the requirement of EPA is the polarized light microscopy (PLM asbestos test method) analysis with specialized microscopes. The results of asbestos testing establish the percentage and type of asbestos present in the sample material.The Environmental Protection Agency (EPA or sometimes USEPA) is an agency of the federal government of the United States charged with protecting human health and with safeguarding the natural environment: air, water, and land. The EPA began operation on December 2, 1970. The current Administrator (as of 2006) is Stephen L. Johnson.If you would like to know, where you can find EPA regional offices and the list of EPA administrators you need to check the following URL: http://en.wikipedia.org/wiki/EPA.Asbestos Fiber Analysis (PLM Test Method)The purpose of the Bulk Asbestos Program is to accredit testing laboratories to assure that they are competent to analyze bulk samples for asbestos testing, using polarized light microscopy (PLM).National Institute of Standards and Technology (formerly the National Bureau of Standards) develop an accreditation program for laboratories conducting analyses of bulk samples of asbestos-containing material.You can find the accredit asbestos testing laboratories list here: http://ts.nist.gov/ts/htdocs/210/214/scopes/plmtm.htmAsbestos Lawyers are the lawyers that specialize in the cases dealing specifically with the hazardous effects induced by Asbestos exposure.
