Pit Bulls: Dog Breed Discrimination With Breed Specific Laws | Global Animal - 0 views

  •  
    (DOGS/DOG BREED DISCRIMINATION) Pit bulls have been the target of breed-specific legislation for years despite evidence these laws do not diminish dog attacks.

How are rainbows made? - 0 views

  • The birth of each rainbow begins with millions of tiny rain droplets.  The rain droplets serve as a type of reflector of light.  White light enters one individual rain droplet and exits as one specific color of the spectrum.  Without millions of rain droplets, a rainbow would not occur.  If you only had a few rain droplets you would only see a few colors.  This is typically why rainbow appear after a rain storm
  • Each rain droplet has a function in the formation of the rainbow. Sunlight enters the rain droplet at a specific angle and the rain droplet separates the white light into many different colors.  This angle is a fixed measurement between your eye
  • and the sun.  What color is refracted depends upon the critical angle,                   which is the angle the sunlight strikes the back of the rain droplet.  Red light bends the least, exiting the rain droplet at a 42 degree angle, while Violet light bends the most, exiting the rain droplet at a 40 degree angle.  All of the other colors of the rainbow exit the rain droplets at some angle between 40 and 42 degrees, thus making up the colors of the rainbow ROYGBIV, this order never changes.

  • Each rain droplet reflects all colors at a given point and time, but only one color comes back to your eye, requiring million of rain droplets to create a rainbow.  As the rain droplets fall through the sky, the colors of the spectrum being reflected and refracted are constantly changing.
  • The perfect time and place to look for a rainbow you need bright sunlight to your back and rain clouds off in the distance in the direction of your shadow. If it is later than 4:30 in the afternoon or earlier than 8:30 in the morning at these condition there is a very good chance you will be able to see a rainbow in the sky.  Other places you may see rainbows formed are fountains, in the ocean as the waves crash against the rock which create a mist in the air, waterfalls, sprinklers and mist from a garden hose. Always remember to have the sun at your back to see a rainbow, happy rainbow hunting!!!!!!
  • Rainbows form a complete circle, however only half is visible.  The horizon only  Picture from the web site of the Department of Physics and Astronomy, Arizona State University                                                             allows us to see half of the rainbow circle, so we see just an arc.  What causes the rainbow to have a circular formation is the way that rain droplets fall.  The rain droplets do not fall is flat sheet, however they tend to fall at various distances and speeds.  On some occasions you can see a full circle around a garden hose.

      each rainbow is made by millions of rain droplets. the rain droplets make a reflect of light and it makes different colors. While light comes in a specific Droplet then it makes a specific color. Without milions and milions of rain droplets the rainbow cant be formed. If you only have a few rain droplets then you will only see a few colors. This is the reason why they happen after a rain storm.

      Each rain droplet that rains  is always useful to make a rainbow because every rainbow needs to do something different to make a rainbow. The rain droplets separates the light into different colors.

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.

      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.

Are Cats and Dogs Color Blind? Yes, Technically They Are - 0 views

  • Cats and dogs are just like color blind humans, seeing some colors but not all of them. For the bright daytime light, cells known as cones are needed. Humans have three kinds of cones, enabling them to see blue, red and green.
  • Cats and dogs, on the other hand, have just two kinds of cone cells (blue and green sensitive), allowing them to see only partial color.
  • while we’re on the subject, contrary to the legend that cats can see perfectly in total darkness, they do not have those superpowers. But cats require only about one-sixth of the light that humans do, making their night vision a whole lot better than ours

  • cats, missing out on seeing life in glorious full color is really no big deal. Brightness and motion are far more important aspects of what our pets see.

      a cat can see only 2 colors, blue and yellow correctly. for example the color red they see it like a yellow green color. Green is correct too  but it is in a different shade of green. Cats as same as dogs have only tow cells of color to make them see only some colors.

This Is How Cats See the World | WIRED - 0 views

  • For starters, cats’ visual fields are broader than ours, spanning roughly 200 degrees instead of 180 degrees, and their visual acuity isn’t as good. So, the things humans can sharply resolve at distances of 100-200 feet look blurry to cats, which can see these objects at distances of up to 20 feet. That might not sound so great, but there’s a trade-off: Because of the various photoreceptors parked in cats’ retinas, they kick our asses at seeing in dim light. Instead of the color-resolving, detail-loving cone cells that populate the center of human retinas, cats (and dogs) have many more rod cells, which excel in dim light and are responsible for night-vision capability. The rod cells also refresh more quickly, which lets cats pick up very rapid movements — like, for example, the quickly shifting path a marauding laser dot might trace. Lastly, cats see colors differently than we do, which is why the cat-versions of these images look less vibrant than the people-versions. Scientists used to think cats were dichromats — able to only see two colors — but they’re not, exactly. While feline photoreceptors are most sensitive to wavelengths in the blue-violet and greenish-yellow ranges, it appears they might be able to see a little bit of green as well. In other words, cats are mostly red-green color blind, as are many of us, with a little bit of green creeping in.

How Do Broken Bones Heal? - Health News and Views - Health.com - 0 views

  • Bones are flexible enough to give a bit when physical force is applied, but if that force is too great, they’ll snap like a plastic ruler bent too far. Luckily, they also repair themselves naturally (even better with a cast). Here’s how bones heal. 1. Immediately after a fracture occurs, a blood clot and callus form around it. 2. New “threads” of bone cells start to grow on both sides of the fracture line toward one another. 3. Eventually, the fracture closes up and the callus is absorbed by the new cells. This process may take from six weeks to a year.

How do broken bones heal? - HowStuffWorks - 0 views

  • If you experience engine trouble, you take your car to a mechanic. If your pipes leak, you call a plumber. And if you fracture a leg, the usual course of action is to visit a doctor. But unlike other things that may break in life, bones begin healing on their own before you even set foot in a waiting room.The human body possesses amazing healing powers that enable it to bounce back from a vast array of illnesses and injuries. Sometimes broken bones can heal so thoroughly within a few months that even an x-ray can't determine the original fracture line.Doctors often play a vital, sometimes lifesaving, role in a bone's healing process. But, these experts basically help the body heal itself. Doctors provide optimal conditions for bone repair and healing to take place. The rest is up to your cells.But how does this amazing biological process work? How can a fractured limb grow back to its former strength? To understand, you first have to take a closer look at just what bones are made of and how alive they really are.
