Human cells and animal cells are very similar. Actually, human cells are types of animal cells. Every different tissue in your body is made up of different kinds of cells. They may have different structures, especially in their cell membrane, which make the function of that cell different. Therefore they do have similar functions, depending on their structure and characters.

If the total number of cells you finish with at the end of what I assume is mitosis is 36, then you began with 18 cells, which I suppose is 50%. Is that at all what you are asking?

about 9,000,000 cells

chemical, cellular, tissue, organ, organ system, organism\n\nchemical - stuff that comprises a cell and the processes within\ncellular - smallest unit of sustained life\ntissue - group of cells working together\norgan - a lot of tissue\norgan system - several organs that work together\norganism - a person could be considered an organism.

In animals and plants, cells are the smallest units that can be considered alive. Your body, like all human bodies, is a collection of many many cells. Nearly all cells have the same basic parts - a nucleus, which has DNA, and a cell membrane, which acts as sort of a skin for the cell, keeping insides in, and outsides out. \n\nCells are arranged together to form tissues, which in turn arrange together to form organs, which fit together to form systems (like the digestive system), which in turn all keep you as one functioning living being!\n\nMost cells in a large organism like plants and animals have specialized purposes as well - some are nerve cells, transmitting signals to and from the brain to the rest of the body, some are in your blood, carrying oxygen to the rest of the body, some form your skin, keeping you from getting infected from outside. \n\nCells have their own lifespans, and can reproduce and die.\nSometimes, a mutation happens in cells, and they don't follow their genetic instructions and might grow and reproduce abnormally -- this is what cancer is.

Basically there are numerous cells in the body composing of white blood cell and red blood cell

The world population is the total number of humans alive on the planet Earth at a given time. According to estimates published by the United States Census Bureau,the Earth's population hit 6.5 billion on Saturday, February 25, 2006. In line with population projections, this figure continues to grow at rates that are unprecedented prior to the 20th century. Approximately one fifth of all humans that have existed in the last six thousand years are currently alive. By some estimates, there are now one billion (thousand million) young people in the world between the ages of 15 and 24.

In every cell of the human body there are 46 chromosomes: 44 somatic coding chromosomes (body coding) and 2 sex chromosomes.\n\nEach chromosome is part of a pair.  Each one of the pair codes for the same thing, though not necessarily the identical way (for example, one of the set may code for blue eyes, one may code for brown eyes). \n\nThe idea of homologous pairs is important during meiosis, when the chromosomes replicate, and find their homologous pairing, forming a tetrad (a structure with 4 chromatids from the joining of 2 replicated homologous chromosomes).\n\nHope this helps.

White blood cell count (WBC). The number of white blood cells in a volume of blood. Normal range varies slightly between 4,300 and 10,800 cells per cubic millimeter (cmm). This can also be referred to as the leukocyte count and can be expressed in international units as 4.3 - 10.8 x 109 cells per liter. Leukopenia is present when the count falls less than 1000/mm3, the risk of infection increases drastically. LEUKOPENIA IS NEVER NORMAL, can be caused by radiation, anaphylactic shock, systemic lupus erythematosus, and certain chemotherapeutic agents.

The longest cells in the human body are the motor neurons. They can be up to 4.5 feet (1.37 meters) long and run from the lower spinal cord to the big toe. The longest living cells in the body are brain cells which can live an entire lifetime.

At birth the human body has about 350 bones, but by the time adulthood rolls around, some of our bones have fused together to give us a total of 206 bones in our body!\n\nHere is the breakdown:\n\nThe adult skeleton consists of 206 bones . . .\n\n- 28 skull bones (8 cranial, 14 facial, and 6 ear bones);\n\n- the horseshoe-shaped hyoid bone of the neck;\n\n- 26 vertebrae (7 cervical or neck, 12 thorax, 5 lumbar or loins, the sacrum which is five fused vertebrae, and the coccyx, our vestigial tail, which is four fused vertebrae);\n\n- 24 ribs plus the sternum or breastbone; the shoulder girdle (2 clavicles, the most frequently fractured bone in the body, and 2 scapulae);\n\n- the pelvic girdle (2 fused bones);\n\n- 30 bones in our arms and legs (a total of 120);\n\n- There are also a few partial bones, ranging from 8-18 in number, which are related to joints.

300-450 white cell is a normal reading even if you get your blood done. Your body replaces the missing ones in a matter of hours. Our body is capable of amazing feats.

Unfortunately there isnt any average cell-as said before, there is variation from minutes, in the case of some immune and germ cells, to never in the case of most neurons.  But, to give you a way to answer your homework, you can say a hypothetical cell takes 24 hours to divide-there are quite a few cell types that take about this long, so you would be safe choosing this time.

This would obviously be very approximate.\n\nEach cell contains about 6 feet of DNA.\n\nThe average human body contains between 50,000,000,000,000 and 75,000,000,000,000 cells.\n\nSo, thats between 300,000,000,000,000 feet and 450,000,000,000,000 feet of DNA.\n\nSo in miles that would be between 56,818,181,818 miles and 85,227,272,727 miles.\n\nReferences:\n6 feet of DNA in each cell:\nhttp://www.life.uiuc.edu/hughes/footlocker/Activities/Cheek_DNA.pdf\n\nCells in the human body:\nhttp://science.enotes.com/science-fact-finder/human-body/how-many-cells-human-body\n\nFeet to Miles Conversion:\nhttp://www.onlineconversion.com/length_common.htm

Cells, of course, vary in size. The largest cell on earth is an ostrich egg. The smallest cell is a tiny bacteria. In warm-blooded animals, the reproductive cells are the largest and the smallest — in other words, the sperm cell is the smallest cell in the body of a human or any other mammal, and the egg cell is the largest.\n\nThe largest cell in the human body is the female ovum, or egg cell. It is about 1/180 inch in diameter. The smallest cell in the human body is the male sperm. It takes about 175,000 sperm cells to weigh as much as a single egg cell.
