What percent of the cells life cycle is involved in nuclear divisions?
The M phase, or mitosis, is a brief period of time in nuclear division. This is the separation of the chromosomes into two matching nuclei.
What happens when you have 2 nuclei in one single cell?
The only time there can be 2 nuclei in a single cell is during mitosis, where one cell multiplies and becomes 2 cells.
Where and in what form is eukaryotic DNA found?
DNA is stored in threadlike, tangled structures called chromatin inside the nucleus of a eukaryotic cell. During mitosis, chromatin changes into structures called chromosomes. Each time the cell divides, the genetic information carried by the chromosomes is passed to the two newly formed cells, where it is stored as DNA in their nuclei.
Why was if difficult to find interphase cells in the whitefish blastula slide?
This is because the cells divide so rapidly that Interphase is such a short period of time; thus, few cells are in Interphase.Read more: Why_was_if_difficult_to_find_interphase_cells_in_the_whitefish_blastula_slide
What are cells that do have a nuclei?
Nucleus is an imp component of cell essential for survival . An organised nucleus appears in eukaryotes(except mammalian rbc and sieve tube cells of phloem) for the first time .Prokaryotes have an unorganised nucleus....
Does red blood cells contain nuclei?
Red cells, at one time contained nuclei; however, when circulating in your blood stream, they do not.

What are Cells called that reside in a specific connective tissue type for an extended period of time?
Stem cells
What is the period when cell divide to create cells is called?
generation time
What collection of cells that come together for a period of time and then separate?
An aggregation
What process might have caused the first cells to spontaneous generate over time a very long period of time?
Chemical evolution is thought to have caused the first cells to spontaneously generate over a very long period of time.

What happens to muscle cells over a period of time if you don't exercise?
They atrophy
