What are three sources of signals related to the regulation of cel growth and division?
Three sources of signals related to the regulation of cell growth and division are growth factors, hormone signals, and signals from neighboring cells. Growth factors are molecules released by cells that promote cell proliferation. Hormone signals, such as those from the reproductive system, can also influence cell growth and division. Signals from neighboring cells, called contact inhibition, can regulate cell growth by preventing cells from dividing when they come into contact with other cells.
Kinases and growth factors control what in the cell cycle?
Growth factors allow the cells to rapidly divide once they are anchored to a surface. Once the cells use up all of the growth factor (or they start to bump into each other) they will stop diving. Kinase is a regulatory protein that aids in the "stop" and "go" portion of the cell cycle.
Is the healing of a wound an example of mitosis?
Yes in the sense that the new growth of cells the covers/mends the wound. But the growth of new cells by mitosis doesn't necessarily "heal" - there are a variety of factors in the healing process.
What recent factors have contributed to prison growth?
what recent factors have contributed to correctional growth
Why is it important that cell growth in a multi- cellular organism be regulated so carefully?
In multicellular organisms, cell division must be carefully regulated to ensure that growth of the organism is coordinated, replacement of dead cells takes place in an orderly fashion, and repair of injured cells is initiated when needed. Cell division must also be halted when growth and repair are completed. Cell division is controlled by a variety of factors. One of the most important controls is carried out by molecules called growth factors.
Are growth factors local regulators that are produced by the anterior pituitary?
No. Growth factors are local regulators that bind to cell-surface receptors and stimulate growth and development of target cells.
What could happen to target cells in an animal that lack receptors for logical regulators?
Target cells in an animal that lacks receptors for logical regulators could result in the inability of the cells to multiply in response to growth factors from cells that are nearby. Target cells are also referred to as codocytes.
Proteins called growth factors regulate the timing of the cell cycle in eukaryotic cells?
no

Why do the epidermal cells have had there edges folded over?
The epidermal cells have their edges folded over which is part of the structure. This is as a result of the growth factors which makes the cells to proliferate.

What is a inhibition?
A density dependent inhibition is when cells become more and more numerous, the required growth factors and nutrients become insufficient making cell growth difficult.

What is a growth defect in cells?
A growth defect in cells is called you !
What is One of the factors of a cell that leads to mitosis?
Factors that affect cell division, that is if cells divide or not, can be categorized into internal factors, growth factors and external factors. For more information it is best to study literature on the subject.
What are unidentified growth factors?
Growth factors are hormones or chemicals that regulate the growth in certain animals. Unidentified growth factors have not been studied in detail yet.
How the presence of a cancerous tumor affect the biological processes?
Cancerous tumours are formed from cells which have had mutations in very specific genes which have allowed them to survive independantly of cells around them in the body. Some of these key genes code for growth factors and other proteins which affect normal body cells. Often the tumour cell mutations cause upregulation of these growth factors causing neighbouring healthy cells to be affected in unusual ways.
