Life is existing, continuity, living, present in the body - fun and challenge are a part of life, including suffering, pain, joy, prosperity etc.\nOne who expects to go through life without challenges and problems is an unfortunate one.

Absolutely..Cell Bio is a great area.  I've been dealing with cell biology for a whole lot of years,  and I still find it fascinating.

hi, i work 4 a book company, and 1 of our regular books is on cell and molecular biology, if you email me, i can probably give you an answer on exactly what ur question is.

Very big cells usually can't survive because the ratio of their surface area to their volume is too small, and they can't get enough nutrients in and waste out. So maybe a faster method of exchanging substances with its environment? Sorry if I'm not much help.

I am a Christian and I have found remarkable facts that have bolstered my faith in Intelligent Design. To name one, Irreducable Complexity. It is the fact, (Not Theory) that the simplest cell in our body was created completely in a moment's time, instead of a gradual evolution. It is like a mouse trap. There's a board, spring, lever, and latch. The cell, like the trap, has components that compliment each other in the same way the trap does. If you took one component away the trap would be defective, likewise if the cell is left without all the necessary systems it will perish leaving no time for evolution.

Lets see, \n2. the cell of a  univellular organism is more simpler than a cell of a multicellular organism because the single cell performs all life functions\n5.depends\n3. it may be digests?? because ingests means to take in food . . . not really to break the food down\n6.Changes

It varies with the cell you are discussing. Anywhere from less than 5 minutes to over 70 years.

I'm a biology teacher, and a cell model is a project every year.\n\nUse a HARD beachball about the size of a basketball....or a cheap dimestore basket ball. Cut in in half and use thin wires to suspend the various organelles inside.

practicaly anithing!! Stem cells can replicate themselves or make any type of cell required to build an organism.

if ur talking about cells... i think it is organelles...not sure
