definition of viable and non-viable cells?
967036
You need to define "viable and non-viable" cells....if DNA is still present for reconstruction of crime or accident...then the cells are viable.\n\nIf you are wanting to grow cells in a medium..then if the cell walls are intact and no damage to the cell structure has occurred...then the cell will be viable...\n\nmaybe this will help\n\n\nGood luck

Non-living. It cannot reproduce by itself, cannot regulate homeostasis, depends/hijacks other hosts for reproduction. It's mostly leftover/waste DNA of some bacteria/protist that ejects their DNA into the air with a protein capsule to reproduce, although this didn't work.

there are several, one is a vacuole. It is used to store soemthing usually food within the cell

Hard question to answer.  i seem to remember a professor talking on this very subject so i will try and do him justice.\n\n1) surface tension of the phosopholipid bilayer cannot remain bound together once a cell reaches a certain size. another factor is genetic. the genome (depending on the cell type) has a pre determined size. once it is reache a phenominon called apoptosis or cellular suicide is activated bringing a wierd meaning to the welfare of the many outways the welfare of the one. anther aspect is environment.  depending on the cell and the environment it finds itself in, it must compete for for food.  larger cells need more food.  If the food source of the environment is scarce then it wil die as a result of starvation.  in biologic systems immune resppnse may play a significant factor in making the environment too hostile for life.  However lare single cell organisms do exsist.  I will not hand you the answer but I will give you a hint.  Look to Marine life..  good question!

this is a good question. what decides a cell living or nonliving is its metabolic activity. ..now you got me thinking... \n\nBut  to clear some confusion, they don't have nucleus, and that's why they can't reproduce by themselves.\n\nK...finally got some info from a very good friend, a hematologist. Here is what he says...\n\n"The question you asked is a very very deep one indeed.  In fact, we can have a very lively debate about it.  It is a very philosophical question, in that it's equivalent to asking, "Is virus a living organism?"  If we define life, as you say, by metabolic activities, then yes, red blood cell is a living cell.  Red blood cell uses the metabolic pathway of glycosis to generate energy.  It also has a variety of proteins and enzymes responsible for signal transduction.\n \nHowever, a red blood cell is a terminally differentiated cell and more than that it lacks the genetic material, the means and the mechanism to replicate.  Given that one of the primary goal of life is to have "offsprings" either through asexual replication or sexual duplication, red blood cell lacks that ability.  However, the progenitor of red blood cell (hematopoietic stem cells) does have the ability to replicate and differentiate."

Precancerous cells are cells that may, or are likely to, become cancer.\n\nPrecancerous cells have little capacity to repair their DNA and so are more likely to become cancerous.

It is the simplest form of a cell membrane. Actually the cell on contain es the cell membrane and nothing else. It is used for research when doing tests on a cell membrane. It has nothing that could interfere with normals.

Normal cells have a standard lifetime.  They die after a given number of generations.  It's a natural process thought to be caused from shortening of the telomeres in the chromosomes (simple explanation).  \n\nCancer cells are able to multiply indefinitely.  That is why they are so dangerous in the body--having a mass of cells that multiply indefinitely eventually kills.  But in cell culture, having a cell line that lives pretty much forever makes them easier to use.

stem cells are cells that haven't differentiated into specific types (like liver cells, lung cells, or skin cells). they are very useful for scientists becuase they haven't differentiated and can be turned into whatever cells are necessary. try google to find more about them but try to stay away from anything political.

eukaryotic\n\neu means true\nkary refers to nucleus\n\nwe have true nuclei in our cells

This tells you that these cells do not readily divide. So onece there is damage in the spinal cord there are no cell divisions to replace the harmed cells.\n\nCommonly these non-dividing cells are said to be in the G0 phase.

1)  The cell is the unit of structure, physiology, and organization in living things. \n   2)  The cell retains a dual existence as a distinct entity and a building block in the   construction of organisms. \n   3)  Cells form by free-cell formation, similar to the formation of crystals (spontaneous generation).\n\nKeep this as hint and do your homework

A Eukaryote cell is a cell with a nucleus.  A prokaryotic cell is a cell without a nucleus.  Eukaryotic Cells usually refer to the complex cells of multicellular organisms such as animals plants and fungi, whereas many simpler unicellular organisms are made up of the simpler prokaryotic cells.  \n\nA nucleus is the command center of the cell and stores genetic information.  In eukaryotic cells the genetic information is stored in the cytoplasm, or gooey substance that makes up the inside of the cell.

harmless\n\n\nIn the biological and medical sciences, deleterious means something harmful, such as:\n\nIn genetics, a deleterious mutation, meaning a mutation that results in a negative consequence for the organism, usually at the whole animal level. Many mutations are lethal.

Replicate everyday: epithelial cells (skin, mucosa), bone marrow progenitor cells, lymphocytes (some of them)\nDo not replicate: neurons, skeletal muscle cells, neutrophilic granulocytes, any terminally differentiated cell

That depends on the type of cell and its function.
