The Earth Life Web, the Fish Eye and Sight in Fish - 0 views

  • For sharks and Rays this is not a problem as they do not have color vision anyway. The eyes of shallow water species are adapted to have a maximum sensitivity to light of around 500 nanometres, and the eyes of those species that live in deeper waters are adapted to 475-480 nanometres. Most Teleost fish however have color vision, and the eyes of the Trout (Onkorhynchus mykiss) have three sensitivity peaks at, 455, 530 and 625 nanometres.

      Sharks and Rays are color blind so they don't care about how deep they go cause the deeper you go the less color you see, the fish,sharks,rays,etc that live deeper in the ocean they used to 475-480 nanometers

      However teleost fish have color vision and the trout have three sensitivity limits at, 455, 530 and 625nanometers so they can see the colors in the water if they go deeper they would not see anything

What Are Taste Buds? - 0 views

  • When you have a cold or allergies, and your nose is stuffy, you might notice that your food doesn't seem to have much flavor. That's because the upper part of your nose isn't clear to receive the chemicals that trigger the olfactory receptors (that inform the brain and create the sensation of flavor).

      When you're sick and your nose is "stuffy" you may notice that the food that you eat doesn't have much flavor. Thats because the upper part of the nose doesn't receive the chemicals that lets the brain know how the food tastes. That's why you may not find that kind of strong flavor in your food.

Moons of Jupiter - Wikipedia, the free encyclopedia - 0 views

  • For two decades no additional moons were discovered; but between October 1999 and February 2003, researchers using sensitive ground-based detectors found and later named another 34 moons,

      On 1999 to 2003 34 more moons of jupiter were discovered.
  • The moons' physical and orbital characteristics vary widely. The four Galileans are all over 3,100 kilometres (1,900 mi) in diameter; the largest Galilean, Ganymede, is the ninth largest object in the Solar System, after the Sun and seven of the planets (Ganymede being larger than Mercury). All other Jovian moons are less than 250 kilometres (160 mi) in diameter, with most barely exceeding 5 kilometres (3.1 mi). Orbital shapes range from nearly perfectly circular to highly eccentric and inclined, and many revolve in the direction opposite to Jupiter's spin (retrograde motion). Orbital periods range from seven hours (taking less time than Jupiter does to spin around its axis), to some three thousand times more (almost three Earth years).

JUPITER's Great Red Spot - EnchantedLearning.com - 0 views

  • Jupiter's Great Red Spot was discovered in 1664 by Robert Hooke. Part of the reason it lasts so long in comparison with Earth storms (other than the huge difference in scale and the existence of an internal heat source on Jupiter) is that this storm never goes over land; on Earth, hurricanes loses most of their energy and die when they stray over land.

The Healing Properties of Tears: 7 Good Reasons to Cry Your Eyes Out - Beyond Blue - 0 views

  • 1. Tears help us see. Starting with the most basic function of tears, they enable us to see. Literally. Tears not only lubricate our eyeballs and eyelids, they also prevent dehydration of our various mucous membranes. No lubrication, no eyesight. Writes Bergman: “Without tears, life would be drastically different for humans–in the short run enormously uncomfortable, and in the long run eyesight would be blocked out altogether.”
  • 2. Tears kill bacteria. No need for Clorox wipes. We’ve got tears! Our own antibacterial and antiviral agent working for us, fighting off all the germs we pick up on community computers, shopping carts, public sinks, and all those places the nasty little guys make their homes and procreate. Tears contain lysozyme, a fluid that the germ-a-phobic dreams about in her sleep, because it can kill 90 to 95 percent of all bacteria in just five to 10 minutes! Which translates, I’m guessing, to three months’ worth of colds and stomach viruses.
  • 3. Tears remove toxins. Biochemist William Frey, who has been researching tears for as long as I’ve been searching for sanity, found in one
  • ...5 more annotations...
  • study that emotional tears–those formed in distress or grief–contained more toxic byproducts than tears of irritation (think onion peeling). Are tears toxic then? No! They actually remove toxins from our body that build up courtesy of stress. They are like a natural therapy or massage session, but they cost a lot less!
  • 4. Crying can elevate mood. Do you know what your manganese level is? No, neither do I. But chances are that you will feel better if it’s lower because overexposure to manganese can cause bad stuff: anxiety, nervousness, irritability, fatigue, aggression, emotional disturbance and the rest of the feelings that live inside my happy head rent-free. The act of crying can lower a person’s manganese level. And just like with the toxins I mentioned in my last point, emotional tears contain 24 percent higher albumin protein concentration–responsible for transporting many small molecules (which has to be a good thing, right?)–than irritation tears.
  • 5. Crying lowers stress. Tears really are like perspiration in that exercising and crying both relieve stress. For real. In his article, Bergman explains that tears remove some of the chemicals built up in the body from stress, like the endorphin leucine-enkaphalin and prolactin, the hormone I overproduce because of my pituitary tumor that affects my mood and stress tolerance. The opposite is true too. Bergman writes, “Suppressing tears increases stress levels, and contributes to diseases aggravated by stress, such as high blood pressure, heart problems, and peptic ulcers.
  • 6. Tears build community. In her “Science Digest” article, writer Ashley Montagu argued that crying not only contributes to good health, but it also builds community. I know what you’re thinking: “Well, yeah, but not the right kind of community. I mean, I might ask the woman bawling her eyes out behind me in church what’s wrong or if I can help her, but I’m certainly not going to invite her to dinner.” I beg to differ. As a prolific crier, especially on video, I always come away astounded by the comments … the resounding support of people I know all that well, and the level of intimacy exchanged among them. Read for yourselves some of the comments on both my self-esteem video and my recent death and dying video and you’ll appreciate my point. Tears help communication and foster community.
  • 7. Tears release feelings. Even if you haven’t just been through something traumatic or are severely depressed, the average Jo goes through his day accumulating conflicts and resentments. Sometimes they gather inside the limbic system of the brain and in certain corners of the heart. Crying is cathartic. It lets the devils out. Before they wreak all kind of havoc with the nervous and cardiovascular systems. Writes John Bradshaw in his bestseller “Home Coming”: “All these feelings need to be felt. We need to stomp and storm; to sob and cry; to perspire and tremble.” Amen, Brother Bradford!

Why is the Sky Blue - Space Black - Sunset Red? - 0 views

  • In space, there is no air. Because there is nothing for the light to bounce off, it just goes straight. None of the light gets scattered, and the "sky" looks dark and black.

      In the space there is no air because there is no particles or molecules for it to bounce and scattered so it has no color so it is just dark. And the sky looks dark,black in the night. Because there is no sun and the sun gives light to the molecules and particles.

Jupiter - 0 views

  • Jupiter has a very faint ring system, but is totally invisible from the Earth. (The rings were discovered in 1979 by Voyager 1.) The atmosphere is very deep, perhaps comprising the whole planet, and is somewhat like the Sun. It is composed mainly of hydrogen and helium, with small amounts of methane, ammonia, water vapor and other compounds. At great depths within Jupiter, the pressure is so great that the hydrogen atoms are broken up and the electrons are freed so that the resulting atoms consist of bare protons. This produces a state in which the hydrogen becomes metallic.

Solar System Exploration: Planets: Jupiter: Rings - 0 views

  • All four giant planets in our solar system, including Jupiter, possess a system of rings. Unlike the brilliant, icy rings of Saturn, Jupiter's rings are tenuous, dusty structures. And although Saturn's iconic rings were first spied by Galileo in 1610, Jupiter's faint rings were not spied until the 1970s, when spacecraft first visited the Jupiter system.
    • Esteban Cantu
       
      All gas giants in our solar system have rings. Jupiter's rings aren't similar to saturn's, because they are made out of ice and jupiter's appear to be made out of dust. jupiter's rings were discovered in 1970.
  • The rings appear to be created by dust thrown off by impacts on small moons that orbit within them. The gossamer rings actually outline the orbits of the moons Amalthea and Thebe. The moons Adrastea and Metis skirt through the outer edges of the main ring.
    • Esteban Cantu
       
      Scientist believe that jupiter's rings were created by dust that has fallen off some of jupiter's moons by impacts.
