A chromosome contains genes that determine many physical characteristics. There are 46 chromosomes (23 pairs) in a human body cell with the exception of the sex cells. One of each pair is inherited from the mother's egg, the other from the father's sperm. When the sperm and egg unite in fertilization, they create a single cell, or zygote, with 46 chromosomes. When cell division occurs, the 46 chromosomes are duplicated and the process is repeated billions of times over, with each of the cells containing the identical set of chromosomes. Only the gametes, or sex cells, are different.
With the FoodSaverÂ® Food Preservation System, you can extend that shelf life to about two to three years. Vegetables are also well-suited for freezer storage, but it's important to blanche these foods before vacuum sealing, as this may further extend the shelf life from eight months to about two to three years.
If vacuum sealed properly, this product should last for up to 1 year. If refrigerated, ground meat should last for 1 month. Fish: To maximize product life, store fish in the freezer. Once frozen, vacuum packaged fish will last for up to 2 years.
