How many times does the cell divide during mitosis?
In mitosis the cell divides once. The two cells, in some cases, may then divide again, but mitosis is just one cell dividing into two cells.
How many times does the parent cell divides in mitosis?
Once, and then the two daughter cells can grow and later divide.
Explain why a virus might exist for years and only become active once it comes into contact with a living cell?
A virus can remain dormant for years because it is not a living organism and does not have the ability to replicate on its own. Once it comes into contact with a living cell, the virus can hijack the cell's machinery to replicate itself and cause an infection. The activation of the virus is triggered by specific signals or conditions present in the host cell.
What is the g0 of interphase?
The G0 phase of the cell cycle is a resting phase where cells are not actively dividing. Cells in G0 have exited the cell cycle and are not preparing to divide. They may re-enter the cell cycle if appropriate signals stimulate them to do so.
How do virus breathe?
Viruses do not breathe because they are not living organisms. They are considered particles that need a host cell to replicate and survive. Once a virus infects a host cell, it uses the cell’s machinery to replicate itself.
Do Viruses multiply through binary fission?
No, they do not. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again.No, only living cells divide by binary fission. Viruses are not alive.
A substance is organic if it did not arise from materials that were once part of a living thing true of false?
False. A substance is organic if it contains carbon-hydrogen bonds, regardless of whether it originated from living or non-living sources.
What cell divides infrequently?
Liver cells divide about once a year, and neurons (nerve cells) never divide once we are born (and when they are mature).
Can metamyelocytes divide?
No they can not divide. The final multiplying cell in the neutrophil production is myelocyte. Once myelocyte is differentiated to metamyelocyte, it can not divide afterward. The histology shows no nucleoli in metamyelocyte that we see in myelocyte.
How many times does a cell divide into a million cells?
Just once, after it divides into a million cells it will get bigger.
Which of these cells is likely to NOT continue to divide?
A nerve cell is likely to not continue to divide.
How many times does the cell divide during mitosis?
In mitosis the cell divides once. The two cells, in some cases, may then divide again, but mitosis is just one cell dividing into two cells.
How do viruses get into bacterial cell?
A virus has proteins on its capsid that bind to living host cell. Once the virus has attached it enters the cell or inserts DNA/RNA into the cell.
How a virus tricks a cell to enter?
They are like cockle burrs that "grab" hold of your clothing or a dog's coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts.
Once a virus has entered a living cell what does it force the cell to do?
Once inside a living cell, a virus hijacks the cell's machinery to replicate itself, producing more viruses. It does this by taking control of the cell's protein synthesis and genetic material, ultimately leading to the destruction of the host cell when the new viruses are released.
What are the weaknesses of the tobacco mosaic virus hypothesis?
Tobacco Mosaic Virus (TMV) will not multiply unless it is brought in contact with a living cell and once it contacts the living cell it will not stop its multiplication.
What are the strengths and weaknesses of the tobacco mosaic virus hypothesis?
Tobacco Mosaic Virus (TMV) will not multiply unless it is brought in contact with a living cell and once it contacts the living cell it will not stop its multiplication.
