Learn about cells, the meaning of cell division, and how cells divide. Discover what the process of cell division is called, and examine the types...
Meiosis produces haploid gametes from somatic cells, which have both copies of chromosomes (46). A haploid (1 set of chromosomes-23) sperm cell and a haploid egg cell fertilize and eventually form a diploid zygote, the cell of a new individual. Rare in vertebrates, aquatic invertebrates, ...
mixture of haploid and diploid. c. Haploid. What type of reproductive life cycle involves an alternation between haploid and diploid cells? What type of cells undergo meiosis? Which cells in your body are haploid? What process produces those cells? In which type ...
from its own species in a condition that we callautopolyploidy(Figure 5). The prefix “auto-” means “self,” so the term means multiple chromosomes from one’s own species. Polyploidy results from an error in meiosis in which all of the chromosomes move into one cell instead of ...
Eggs and sperm, as reproductive cells, each contain only one of the two sex chromosomes as a result of having undergone meiosis , a form of cell division that produces daughter cells containing only one member of each chromosome pair. All eggs therefore contain an X chromosome, but half of ...
How do mitosis and meiosis differ from each other? How might cell division have evolved? What do you mean by cell cycle and cell division? The type of cellular division that produces two cells with the same # and type of chromosomes as the original cell: A) Meiosis B...

and then the memory cells are developed. The first contact with a pathogen produces a primary response that is decreased in intensity. Subsequent exposure with the same pathogen produces a highly intensified secondary response. This shows that our body appears to have a memory of the first ...
Sexual reproduction usually involves the process of meiosis, which is a special type of cell division of germ cells to produce gametes. Asexual reproduction, on the other hand, doesn't involve meiosis and produces genetically identical offspring....
Each type of cell in the human body is specially equipped for its role. Cells of the digestive system, for instance, are vastly different in structure and function from cells of the skeletal system. Cells of the body depend on each other to keep the body functioning as a unit. There are...
