You've asked a rather broad question.\n\nHere's a good place to start:\n\nhttp://en.wikipedia.org/wiki/Kingdom_%28biology%29\n\nMore specific questions would be easier to answer.

>>>if chloropyll is implanted in to an animal cell,would it\n>>>>> become auto trophic\n\nNo. \n\nAs Masyhur points out chlorphyll is just a tiny part of an incredibly complex system of pigments and enzymes needed to harvest light.  It is really akin to asking whether you could glue a carburettor to the side of a cardborad box and turn it into an airplane. \n\nA more plausible route would be to implant entire chlorplasts into an animal cell line. That has potential, but only for narrow range of animals.\n\nSee, the thing about chloroplasts is they need light to work. And the thing about most animals is that they have evolved pigments to stop light penetrating their cells. The two conditions are mutually exclsuive. You could implant or the chlorplasts you like into a human or cockroach and they won't do anyhting because they will be permanently in the dark.\n\nWith transparent animals like jellyfish or glass fish or similar you probably could achieve some level of autotrophic activity. \n\nIn the case of a highly active animal like a fish the payoff wouldn't be worth the cost. Chlorplasts require energy to build and maintain and active animals can't afford to laze around int he sun all day. That's why the ancestors of animals abandoned their chlorophyll in the first place (did you know that all animals are descended from photosyntheic organisms?)\n\nBut with slow moving animals like jellyfish it becomes more plausible. Some jellyfish already utilise symbiotic algae to harvest sunlight, so for those species the addition of inherent chlorpplasts could be a major boon.\n\n>>>>IS IT POSSIBLE \n\nNot with todays technology. However it is entirely possible we could have the technology to implant chlorplasts within our liftimes. I dont; quite see why we would bother, but still.....

frogs need at least enough for them to soak in, and because of evaporating I would make sure it was about twice their height.  But more importantly then the amount of water is the fact you change it often to prevent illnesses.  Then your frog will be happy and so will you

The proteins and phospholipids float freely in the bilayer.\n\nImagine if you filled a bathtub with water and then dumped a box of those styrofoam peanuts into the tub, pretend these are phospholipids. If you spread them out evenly you'd completely cover the surface of the water. Now take your rubber ducky and pretend it's a protein. You could move the ducky (protein) from one point to the other and the phospholipids will shift out of the way and close any gaps. It works this way because it allows the proteins in membrane to move throughout the surface of the membrane and go where they are needed.

Check out "mitosis" in a suitable source (Wikipedia, for example).  The process is a bit long to describe here.

Ok  each cell has its own wall, think of it like a water balloon.  now take a whole bunch of these water balloons and stack them together,  say thats you skin holding all your blood in, ahh but your blood is made up of cells as well.  now when there is a break in the skin blood pours out, why not water? because the water is still contained within each individual cell.  The cells themselves are not broken only pushed apart by whatever is poking you.  that make sense?

A frog is compleately covered by a soft, thin and moist layer of skin make of two very important layers, the epidermis and the dermis.\nIt does not really protect the frog in any way but, it helps in the process of respiration. Oxygen can actually pass through a frog’s skin, which then enters into their blood.\nFrogs dont only breathe though their skin, some adult frogs have two sac-like lungs.\nWhen a frog is sumerged underwater, its respiration takes place through their skin only.\nThere are many blood vessels that run throughout the frog’s skin. Oxygen can actually pass through it, therefore, it directly enters into the blood. Oxygen can be gotten from water too.

"Some frogs have a 3rd eyelid (called a nictating membrane - like dogs) which may be drawn across the eye to protect it, but allowing some partial sight:"\n\nthere you go!

1) The first membrane that a water molecule encounters and passes through is the 'ROOT HAIR CELL MEMBRANE'\n2) Then it passes through all the membranes of the cortical parenchyma of the root in a lateral or roughly horizontal direction (Actual number depends upon the size of the root.)\n3) After entering the xylem element it will not come across any membrane, as the xylem is a dead tissue, and travel in upward direction towards the leaves till it reaches the xylem of a particular leaf. \n4) From the xylem element of the leaf vascular bundle it will enter the mesophyll and in doing so it will once again pass through a cell membrane of that mesophyll cell.  \nNow it is for you to calculate the exact number. I have given you the data.

Frogs may return to where they were born to mate, it depends on many factors. Of course, if they always returned to the same place generation after generation the inbreeding would be horrific, so most frog species disperse- it might only be one sex, but when they become frogs brothers and sisters are competing with each other for food so it is their best interest to find "new ground"- if they find a good pond, they will stay there and breed. You are very lucky to have a frog orgy in your back yard- it indicates a healthy environment.

Their skin. It is permeable to oxygen and carbon dioxide, as well as to water. On land, adult frogs use their lungs to breathe. When a frog is underwater, oxygen is transmitted through the skin directly into the bloodstream. Because the oxygen is dissolved in an aqueous film on the skin and passes from there to the blood, the skin must remain moist at all times.

i dont know if this is true..but i heard once when i was a kid that tadpoles draw the nutrients they need from theyre little tails. i heard that its the same concept as little creatures eating their shells after breaking out of them. This might be urban legend but it makes sense to me! what else happens to their little tails? and please..nobody correct me or i will feel really really stupid for believing this if its not true

It would depend on several factors. Small, uncharged molecules can pass through the cell membrane through diffusion. When it is water, it is called osmosis. Diffusion can only occur into the cell when the concentration of the substance is greater outside the cell than within it, and likewise only out of the cell when the concetration is greater inside the cell than outside. This is called the concentration gradient.\n\nWhen the molecule is charged or is large (such as a chlorine ion or a lactose molecule), it requires active transport by carrier proteins. There are also carrier proteins that help to transport against the concentration gradient.\n\n[Edit] \nAfter thinking for a bit, I believe it would be pertinent to include something about the more complex methods of active transport.\n\nThere are two "directions" of the complex forms of active transport: in (endocytosis) and out (exocytosis).\n\nExocytosis is when a vesicle, after being released from the Golgi complex, fuses to the cell membrane, releasing the contents.\n\nEndocytosis is done by three main means: Phagocytosis, Pinocytosis, and Receptor-Mediated Endocytosis.\n\nPhagocytosis is the process of enveloping a large particle, such as how many unicellular organisms "eat" other organisms. The large particle comes in contact with the cell membrane, stimulating the formation of a vesicle. This vesicle then enters the cell and depending on the contents may fuse with a lysosome to help to digest it.\n\nPinocytosis also forms a vesicle, but differs from phagocytosis because it forms a much smaller vesicle.\n\nReceptor-mediated endocytosis is when particles that cannot normally enter the cell bond to receptor proteins embedded in the cell membrane. These proteins then congregate and form a vesicle. \n\nIn all forms of endocytosis and exocytosis, ATP is required for energy.

I tried on a frog once, I tried to blow in its mouth, sadly it didnt work :(

It has EVERYTHING to do with medicine. just see the doctors response above! It's a confusing response if you don['t understand osmolarity and how the different body compartments work, but a great answer is you do understand it. If you don't understand osmolarity, go to http://www.wikipedia.org
