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....
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.
What happens during the period of the embryo?
During the period of the embryo, which lasts from fertilization to around eight weeks of development, the cells divide and specialize to form the basic structures of the body. Major organs and systems start to form and the embryo becomes more recognizable as a human being. This period is critical for proper development as any disruptions during this time can have lasting effects on the individual.
What happens when you have 2 nuclei in one single cell?
Having two nuclei in one cell is known as "multinucleation." This can result from various causes such as cell fusion or abnormal cell division. Multinucleated cells can exhibit altered function, impaired cell division, and may lead to cell death or abnormal cell behavior.
What process might have caused the first cells to spontaneously generate ove a period of time?
The process that may have led to the spontaneous generation of the first cells is abiogenesis, where simple organic molecules gradually organized and combined to form a primitive cell. This process likely occurred in a conducive environment, such as a primordial soup rich in chemicals and energy sources. Over time, these simple cells evolved and diversified into more complex organisms.
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 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 will cells look like if you treat them with chemicals that block cytokinesis?
Cells treated with chemicals that block cytokinesis will likely have multiple nuclei within a single cell, giving them a polyploid appearance. This will result in enlarged cells with irregular shapes and sizes due to the failure of cell division. Over time, these cells may undergo cell death or develop abnormalities.
What might have caused the first cells to spontaneously generate over 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
