Sexual reproduction involves two reproductive cells called gametes - the female ovum and the male sperm. Each gamete has half the number of chromosomes of a normal cell.
During fertilization the sperm and ovum unite to form a single celled zygote. The zygote has chromosomes from both the ovum and the sperm. This zygote is capable of developing into an individual.
embryo

Zygote
budding or fission

mature
Stem cells come from newly fertilized eggs because those eggs divide and evolve into more specialized cells.
The exact number of egg cells that can be fertilized is exactly the same as the number of egg cells that are available. For example, in a salmon, about 7,000,000. In a human, normally one, occasionally two to three, rarely up to five and very, very rarely up to seven. Just because they 'can be' fertilized though does not mean that they 'will be' fertilized!
Yes. Mitosis is the process of cells separated or dividing to create more cells. this could be dangerous if a cell is mutated and it goes through mitosis producing more mutated cells.
No, cancer cells are more active than normal cells. Cancer cells are always dividing at a faster rate than normal cells.
Mitosis is the process of cells dividing, making more cells. As more mitosis occurs, more cells are made, and thus, the organism as a whole grows.
When a pig egg cells is fertilized the fertilized egg will undergo cell division to produce more cells what is the name of this cell division?

Biologists use dividing cells to determine the number of chromosomes in an organism because when cells go through mitosis (the process of dividing) the chromosomes become much more visible.
Radiation therapy, properly dosed, kills the faster dividing cancer cells at a significantly higher rate than the more slowly dividing healthy cells.

After two gametes fuse to form a fertilized egg, it starts to divide into more cells. In humans, this ball of cells becomes implanted in the wall of the uterus.
Stop dividing.
Yes. Mitosis is the process of cells separated or dividing to create more cells. this could be dangerous if a cell is mutated and it goes through mitosis producing more mutated cells.
because there is more tissue there.
No, cancer cells are more active than normal cells. Cancer cells are always dividing at a faster rate than normal cells.
If the egg was fertilized and more than a clump of stem cells in the physical development portion, then yes you could.
