STRAWBERRY
Strawberry or Fragaria chiloensis L is the fruit of the much-loved by anyone. Benefits of strawberry fruit is also varied. Not only contain lots of vitamin C, but fruit is also rich in antioxidants, folic acid, potassium, ellagic acid, and also fiber.
Not only that, strawberry fruit can help lower cholesterol levels. Together with the grape and cherry fruit, ellagic acid contained in this fruit, capable of preventing carcinogens into kanker.Bahkan a recent study by Dr. Gene Spiller, Nutrition and Health Research Center, showed that eating one serving (about 8-10 pieces / day ) can significantly lower blood pressure. Another study showed that strawberries beneficial to reduce the risk of cancer, reduce the potential for heart disease, improve memory function and rheumatic joint disease. Extraordinary is not it?
If strawberries are consumed on a regular basis every day, then the benefit is the skin becomes more smooth and able to prevent aging due to a very high antioxidant levels. In addition to good for the skin, the fruit can also be used to whiten teeth if consumed.
The benefits of strawberries for beauty among others detoxifies the skin, smooths hair and shrink pores. High content of vitamin C that will clean the skin. Besides strawberries also contain salicylic acid that can remove dead skin cells and shrink pores. While antioxidant helps regenerate skin cells so as to keep looking young.

A RAINBOW
A rainbow is an optical and meteorological phenomenon that causes a spectrum of light to appear in the sky when the Sun shines on to droplets of moisture in the Earth's atmosphere. It takes the form of a multicoloured arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.
In a so-called "primary rainbow" (the lowest, and also normally the brightest rainbow) the arc of a rainbow shows red on the outer (or upper) part of the arc, and violet on the inner section. This rainbow is caused by light being refracted then reflected once in droplets of water. In a double rainbow, a second arc may be seen above and outside the primary arc, and has the order of its colours reversed (red faces inward toward the other rainbow, in both rainbows). This second rainbow is caused by light reflecting twice inside water droplets. The region between a double rainbow is dark, and is known as "Alexander's band" or "Alexander's dark band". The reason for this dark band is that, while light below the primary rainbow comes from droplet reflection, and light above the upper (secondary) rainbow also comes from droplet reflection, there is no mechanism for the region between a double rainbow to show any light reflected from water drops.
It is impossible for an observer to manoeuvre to see any rainbow from water droplets at any angle other than the customary one (which is 42 degrees from the direction opposite the Sun). Even if an observer sees another observer who seems "under" or "at the end" of a rainbow, the second observer will see a different rainbow further off-yet, at the same angle as seen by the first observer. Thus, a "rainbow" is not a physical object, and cannot be physically approached.
A rainbow spans a continuous spectrum of colours; the distinct bands (including the number of bands) are an artefact of human colour vision, and no banding of any type is seen in a black-and-white photo of a rainbow (only a smooth gradation of intensity to a maximum, then fading to a minimum at the other side of the arc). For colours seen by a normal human eye, the most commonly cited and remembered sequence, in English, is Newton's sevenfold red, orange, yellow, green, blue, indigo and violet (popularly memorized by mnemonics like Roy G. Biv). However, colour-blind persons will see fewer colours.
Rainbows can be caused by many forms of airborne water. These include not only rain, but also mist, spray, and airborne dew.
EXPLANATION:
The light is first refracted entering the surface of the raindrop, reflected off the back of the drop, and again refracted as it leaves the drop. The overall effect is that the incoming light is reflected back over a wide range of angles, with the most intense light at an angle of 40–42°. The angle is independent of the size of the drop, but does depend on its refractive index. Seawater has a higher refractive index than rain water, so the radius of a "rainbow" in sea spray is smaller than a true rainbow. This is visible to the naked eye by a misalignment of these bows.
The amount by which light is refracted depends upon its wavelength, and hence its colour. This effect is called dispersion. Blue light (shorter wavelength) is refracted at a greater angle than red light, but due to the reflection of light rays from the back of the droplet, the blue light emerges from the droplet at a smaller angle to the original incident white light ray than the red light. Due to this angle, blue is seen on the inside of the arc of the primary rainbow, and red on the outside.
Contrary to popular belief, the light at the back of the raindrop does not undergo total internal reflection, and some light does emerge from the back. However, light coming out the back of the raindrop does not create a rainbow between the observer and the Sun because spectra emitted from the back of the raindrop do not have a maximum of intensity, as the other visible rainbows do, and thus the colours blend together rather than forming a rainbow.
A rainbow does not actually exist at a particular location in the sky. Its apparent position depends on the observer's location and the position of the Sun. All raindrops refract and reflect the sunlight in the same way, but only the light from some raindrops reaches the observer's eye. This light is what constitutes the rainbow for that observer. The position of a rainbow in the sky is always in the opposite direction of the Sun with respect to the observer, and the interior is always slightly brighter than the exterior. The bow is centred on the shadow of the observer's head, or more exactly at the antisolar point (which is below the horizon during the daytime), appearing at an angle of 40–42° to the line between the observer's head and its shadow. As a result, if the Sun is higher than 42°, then the rainbow is below the horizon and usually cannot be seen as there are not usually sufficient raindrops between the horizon (that is: eye height) and the ground, to contribute. Exceptions occur when the observer is high above the ground, for example in an aeroplane (see above), on top of a mountain, or above a waterfall.

BENEFITS OF KIWI FRUIT
you would know if the kiwi fruit is very good for the skin. but in addition to beauty, it is also good for health. example is as an antioxidant. in addition, kiwi fruit was also beneficial to enhance the ability of the brain.
kiwi fruit although not as popular as other fruits, vitamin content fairly complete. in medicine, kiwi fruit can be transformed into a compound capable of binding to cancer. a kiwi fruit is sufficient to meet the requirements of vitamin C intake of adults.
content of vitamin C in kiwifruit is greater than twice that of oranges and 17 times more than apple. in addition, kiwi fruit also contains vitamin B1, B2, B6, and E. the role of vitamins C and E in kiwi fruit serves as an antioxidant, a substance-free antidote to radiation causes aging, and prevention of cancer cells. high content of vitamin C in kiwi fruit makes this fruit can defend the body from the flu and stress.
kiwi fruit also contains high fiber, so it is suitable for those who are on a diet program. Folic acid content was high and rich in vitamin C is also beneficial eliminate dark spots and remove impurities.
besides, the kiwi fruit contained the amino acids arginine and glutamate. arginine is a vasodilator or a decrease in blood pressure and helps improve blood flow. This amino acid also proved able to treat mild symptoms of impotence.
in fact, amino acids can increase a child's thinking ability. please note, the food consumed influential in increasing the ability of the brain. Therefore, besides the fish that have high enough amino acids to intelligence, kiwi fruit is also recommended as a food that has similar benefits with fish.
essential content in kiwi fruit is also very much. such as potassium, calcium, magnesium, zinc, copper, manganese, and phosphorus. mineral potassium in the kiwi could reach 5.4 mg / calories. Potassium works to maintain the function of the nervous system reflex motion and maintain muscle system. This mineral also plays a role as lowering high blood pressure. so that the kiwi fruit can prevent heart attacks and hypertension.
a sweet kiwi fruit flavors mixed with a little acid, capable of providing its own freshness when consumed. can be presented in various preparations, such as pudding, ice cream, cake, or yogurt. like other kinds of fruits, this fruit should be consumed while still fresh, because the nutrient content in it has not gone away.
but it should be noted also that the kiwi fruit can cause allergies in some people. usually in the form of spots laxatives and diarrhea. so, do not be too much too ^___^
