  • 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.

Taste, Information about Taste - 0 views

  • An individual's unique sense of taste is partially inherited, but factors such as culture and familiarity can help determine why one person's favorite food made be hot and spicy while another just can't get enough chocolate.
    • Isabel Herrera
       
      Taste can also depend on your culture or family traditions and that's why some people love spicy food while other people hate it and prefer chocolate instead.
  • Taste occurs when specific proteins in the food bind to receptors on the taste buds.
    • Isabel Herrera
       
      Taste can happen when the protein in the food your eating joins with the receptors in your taste buds.
  • Taste buds for all four taste groups can be found throughout the mouth, but specific kinds of buds are clustered together in certain areas. Think about licking an ice cream cone; taste buds for sweetness are grouped on the tip of our tongue. The buds for sour tastes are on the sides of the tongue and saltyon the front.
    • Isabel Herrera
       
      The taste buds for all "four taste groups" are usually placed all over the mouth, but taste buds for specific kinds are found in a little group somewhere in the mouth. For example, the taste buds for sweetness can be found in a tiny group in the tip of your tongue. The taste buds for sour are found on the sides.

  • People constantly regenerate new taste buds every 3-10 days to replace the ones worn out by scalding soup, frozen yogurt, and the like. Unfortunately, aspeople grow older, their taste buds lose their fine tuning because they are replaced at a slower rate.
    • Isabel Herrera
       
      A lot of people change taste buds every 3-10 days to avoid the taste buds that had been used for hot soup and frozen yogurt. But as people grow older their taste buds starts losing their ability to taste that's why they're replaced.
  • (The number of taste buds varies in different animal species. For example, cows have 25,000 taste buds, rabbits 17,000, and adult people approximately 10,000.)
    • Isabel Herrera
       
      Different animals have different amount's of taste buds, Fore example cows have 24,000 taste buds, rabbits have 17,000 taste buds and adult people have 10,000 taste buds.

      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 
    • deleon6878
       
      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

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,
    • Esteban Cantu
       
      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).
    • Esteban Cantu
       
      Ganymede, one of Jupiter's four galilean moons, is bigger than Mercury. 
  • ...1 more annotation...
  • Main group or Galilean moons: Io, Europa, Ganymede and Callisto. They are some of the largest objects in the Solar System outside the Sun and the eight planets in terms of mass and larger than any known dwarf planet, and Ganymede exceeds the planet Mercury in diameter.
    • Esteban Cantu
       
      4 of Jupiter's moons, the galilean moons, are some of the largest objects in our universe.

Why Do We Change the Clocks Twice a Year? | Wonderopolis - 0 views

  • it’s Daylight Saving Time! Daylight Saving Time (or “Summer Time,” as it’s known in many parts of the world) was created to make better use of the long sunlight hours of the summer. By “springing” clocks forward an hour in March, we move an hour of daylight from the morning to the evening. On the first Sunday in November, we “fall back” and rewind our clocks to return to Standard Time.
    • marino5856
       
      the hour changes to save daylight and light because like we have the sun light we don't need to waste la light. It changes in summer to have more light when it is getting night and in october again so that it is more dark because in winter we don't need so much the light.

      Eagles have very big wings they can carry their big body and some fish.
  • It takes a lot of energy to flap such large wings, just like it's a lot of work running with a large kite until it takes off!
    • Eugenio Ferrara
       
      all eagles have trouble flapping that bi giant wings they need a lot of sterngth and energie

Do Cats Have a Sense of Taste? - 0 views

  • The sense of smell is extremely important in attracting cats (and us) to food and also in aiding tasting food. Cat’s noses are many times more sensitive than our own, so it is believed that their heightened sense of smell assists a great deal in their tasting of different flavors.
    • garza6544
       
      the sence of smell is very important for cats and us and also tastig food. heir nose is like 100 times more sensitive than ours, that helps for taste too.
