atom, molecule, cell, tissue, organ, organ system, and organism\n\nThe rest is a grand surprise that only the elite few can figure out.\n\nDon't hurt yourself with the pages of your Bio book.

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.

biology comes from two words.\n1) bios\n2)logos\n\nbio means life and logus means to study\nso biology is the Discipline of Science dealing with life and living things.It is concerned with the characteristics and behaviors of organisms, how species and individuals come into existence, and the interactions they have with each other and with their environment.

Too many to list and explain here, without copying and pasting  --and why should I do all your uni work for you? ;-)\n\nI will recommend a couple of good text books through.  Well worth a purchase or just get them on loan from your library...\n\nAlberts et al, Molecular Biology of the Cell\nStryer, Biochemistry\n\nIt's been since I bought mine.  Think I got editions 2 & 7 back in 1996 and I know both have been updated a couple of times since.  These are still a GREAT basic resourse for this sort of question.

Question 1: 2 <= result <= 12\nQuestion 2: Food or nothing at all\n\nTherefore science is truth.

Sounds like 1st yr HS biology homework.  Here´s a hint:\nBoth have a nucleus, DNA material, function similarly.\n\nThe rest should be in your text book, just look at the two diagrams and list the similar inner parts of the cells.\n\nOne more hint:\nHow they differ-\nPlant cells have rectangular shapes and have chloroplasts w/ chlorophyl.\n\nAnimal cells are round.

Studying for biology can seem overwhelming, but it doesn't have to be. If you follow a few simple steps, studying for biology will be less stressful and more enjoyable. I've compiled a list of several helpful biology study tips for biology students. Whether you're in middle school, high school, or college, these tips are bound to produce results!\n\nBiology Study Tips\n\nBio-Study Tip 1\n\nAlways read the lecture material before the classroom lecture. I know, I know--you don't have time, but believe me, it makes an immense difference. \n\nBio-Study Tip 2\n\nBiology, like most sciences, is hands-on. Most of us learn best when we are actively participating in a "topic." So make sure to pay attention in lab sessions and actually perform the experiments. Remember, you won't be graded on your lab partner's ability to perform an experiment, but your own.\n\nBio-Study Tip 3\n\nSit in the front of the class. Simple, yet effective. College students, pay close attention. You'll need recommendations one day, so make sure your professor knows you by name and you aren't 1 face in 400.\n\nBio-Study Tip 4\n\nCompare notes with a friend. Since much of biology tends to be abstract, have a "note buddy." Each day after class compare notes with your buddy and fill in any gaps. Two heads are better than one!\n\nBio-Study Tip 5\n\nUse the "lull" period between classes to immediately review the biology notes you have just taken. \n\nBio-Study Tip 6\n\nDon't cram! As a rule, you should start studying for biology exams a minimum of two weeks prior to the exam. \n\nBio-Study Tip 7\n\nThis tip is very important -- stay awake in class. I've observed too many people snoozing (even snoring!) in the middle of class. Osmosis may work for water absorption, but it won't work when it comes time for biology exams. \n\nBio-Study Tip 8\n\nFind some useful resources to help you when you study after class. Here are a few resources that I would suggest to help make learning biology interesting and fun:

1) diffusion of gases in excretory system\n2) their gills pump H20 over one side and splits it up so oxygen flows over teh other to extract 02\n3) C02 diffuses out of cells

Question 1:\n5 Kingdoms- Monera, Protista, Fungi, Plantae, Animalia\nMonera:  are single-celled organisms with no organelles or cell nucleus. Often have cell wall in addition to cell membrane.  (includes all forms of bacteria)\nProtista: single-celled, have organelles and nucleus.  Include yeast.\nFungi: Multicellular, have organelles and nucleus, some go through photosynthesis and produce their own food, while others don't.  (includes mushrooms, bread mold, moss)\nPlantae:  Multicellular, organelles present, nucleated, undergo photosynthesis/so they have chloroplasts (includes all plants)\nAnimalia: multicellular, organelles, nucleated, cannot produce their own food, do not undergo photosynthesis.(animals)\n\nQuestion 2.  SOme say there are 6 kingdoms because Kingdom Monera is divided into Eubacteria and Archaebacteria.  Archaebacteria were the first organisms on the planet, and live under harsh conditions (volcanic hot spots underwater, etc).  Eubacteria are different in structure and are present in friendlier conditions (your bathroom floor, toilet, your intestines, etc)\nScientists do this to separate the two different types of bacteria...although most modern books have them all under Monerans

thats 2 questions & i dont understand either of them

D is the answer.  One cell differentiates and the other cell remains pleuripotent (has the ability to differentiate into many other types of cells).\nHere is why the other choices are incorrect.  Sometimes the other cell will die.  This happens in certain types of ground tissue, but only after the cell has differentiated into a specialized type of cell, which is why A is not the answer.  B is not the answer because gamete in plants is only formed by mitosis.  Only the gametophyte produces gametes and gametophytes are haploid so they only need to undergo mitosis to produce a gamete.  C is not the answer becuase the formation of a zygote requires the fusion of two cells, which does not happen under hte conditions of this question.

2 is always better than 1.  The higher number of sets an organism has, the higher up on the food chain they would be.  An organism with 2 sets of cells would probably eat a 1 cell organism.

Your question requires more knowledge of science and genetics than I have.  However, since you haven't received much help with it I thought I would give you a couple of sites.  Try these - they may be of some help to you.  Sorry I couldn't help more.
