What are some examples of animals without bones?
Such animals are called “invertebrates” and there are many; around 97% of all animal species are invertebrates.Some of the more well-known ones; all insects, arachnids, worms, jellyfish, starfish, crustaceans (crabs, lobsters, shrimps etc), molluscs (mussels, snails & slugs, squid, octopus etc).Here are some unusual and particularly notable ones:Blue Dragon or blue sea slug. If you see one, don’t touch it; they feed on the venom of Man O’ War jellyfish and their tentacles can deliver the same venom if touched.Hummingbird Hawk Moth looks and acts just like a hummingbird.Sea Angel a deep sea mollusc related to snails.Panda Ant a cute fluffy black and white ant that is actually a wingless wasp.
What kind of animals live on both land and water?
Turtles. These are numerous species of turtles that may live on both land and water, like the European pond turtle. Terrapins tend to live in fresh or brackish water.Below water:Above water:Most amphibians. Many only live in water as infants, while others are semiaquatic and can comfortably switch throughout their lifetime.Frogs.Salamanders.Newts (a type of salamander.)Toads.Caecilians.Now, onto mammals. The otter!The beaver.The walrus.The platypus.Birds. In fact, there is an entire family of them: Anatidae, the waterfowl:Ducks.Swans.Geese.There are others, like polar bears, marine iguanas, water monitors, and so on, but at this point I think I’ve sufficiently shown the amazing diversity of semiaquatic animals that reside on this planet. It makes sense, after all. Land covers 29% of Earth’s surface. Water covers the remaining 71%. Why not conquer both?
Why do roosters crow in the early morning?
We have only 1 rooster with our 8 layers, and there are 4 other coops in the area with no other roosters. "Roger" crows all day long, he crows to say hello, he crows when "Ms Thing" (an adventurous hen of ours) escapes the yard. He crows to the east, north, south and west. He crows when each of the girls lays an egg, but he has a special dance and crow for his favorite girl, "Beatrice". He encourages the girls in other coops to lay, crowing when they have announced their fresh laid eggs.He crows when he thinks he's won a battle against myself or my husband, flying to the highest point in the barnyard.He crows at the house if we're late with feed!Roger is quite a talker and it has taken me a long time to figure out what he's saying and to whom. He's the boss of the barnyard, yelling orders all day long.
If London Bridge is standing why is there a song about it falling down?
London Bridge was sold to America some time back: The London Bridge, currently located in Lake Havasu City, Arizona, USA, was originally constructed in London, United Kingdom, in 1831. The bridge was the last project of engineer John Rennie and completed by his son, also named John Rennie. By 1962, the bridge was not structurally sound enough to support the increased load created by the level of modern traffic crossing it, and it was sold by the City of London.
Since water is in a continuous zero-waste cycle, why do we need to conserve it? Sure the Colorado River is running dry, but isn't that water being used, returned to ground water or air humidity, and then deposited elsewhere?
As other answers have pointed out, the question fails to take into account where the water is, not just how much there is total--and only the amount that's safe to drink counts. Salt water and polluted fresh water are useless without treatment--treatment which is often impractical in a given location. Likewise abundant rainfall in Bali won't help anyone in Los Angeles.And the supply of water in any given place varies over time. Droughts happen as part of natural cycles, and man-caused global warming is making weather less certain and more extreme. Water planning should be based on the minima for a region, not the maxima, as seems to be done now.But neither the question nor the other answers (so far) have mentioned the real problem: the number of humans needing the relatively minute drinkable portion of the world's water is not fixed. The world population grows by over 140 people per MINUTE, 24x7. America's population has doubled since 1955. California's population has doubled since 1970--as has the world overall.We can do many things to provide more drinking water. A key one is, across America, building an entire parallel water system to provide non-drinkable water for toilets and non-crop irrigation, and switch over men's urinals to waterless ones. This will cost many, many billions of dollars, along with having to build a huge number of reservoirs to compensate for our destroying all our porous aquifers (the source of nearly all well water) by massive overpumping (a worldwide problem).But nothing we do will compensate for a constantly growing population, which will otherwise absorb every advance in water conservation.Here in California we're about to get mandatory, strict water rationing. Even given the current drought, we wouldn't need that if our population was what it was in 1970--an increase mostly due to immigration to the state, not reproduction per se.One more point: the main source of water for a given country often originates in another country. And if the originating country comes to need that water...well, the downstream country is going to have a lot less water.For example, when America dammed and redistributed the Colorado River, it destroyed a major agricultural region in Mexico. It looks like China is now preparing to do the same thing to Vietnam by damming the Mekong. Some have predicted that the wars of the 21st century will be mostly over water.
What does "chucking" wood mean?
I have heard it a million times, but what does "chucking" wood actually mean? Is this a thing some animals do? I assume it means to remove it from the tree, and do a beaver like action with it, but I have literally never heard it used outside the rhyme. Does it have an actual meaning?
