What is an ischemic cell?
an ischemic cell is a cell that is deprived of o2 and there forth has switched from aerobic metabolism to anaerobic . eventually this will cause the cell to burst because the ATP production is not sufficient to maintain the cell environment
Before mitosis begins which happens before the nucleus starts dividing?
During interphase, which precedes mitosis, the cell grows and replicates its DNA in the nucleus. This prepares the cell for division by ensuring that each daughter cell receives a complete set of genetic material.
In meiosis, the replicating cell starts as a what?
In meiosis, the replicating cell starts as a diploid cell.
What would happen to tissues or organs derived of oxygen for a long time?
Tissues and organs that are deprived of oxygen for a long time can undergo cell death, leading to tissue damage or organ failure. This lack of oxygen, known as hypoxia, can impair the normal function of cells and tissues, ultimately causing them to deteriorate and potentially die.
Explain why DNA replication must occur before mitosis starts?
DNA replication must occur before mitosis starts to ensure that each daughter cell receives a complete and identical copy of the genetic information. If DNA replication did not occur before mitosis, the daughter cells would have only half of the necessary genetic material, leading to genetic abnormalities and potentially cell death.
How long does the blood flow have to be deprived of oxygen before it dies?
Brain cells can start to die within minutes if blood flow is completely deprived of oxygen. Other organs and tissues can sustain longer periods without oxygen, but prolonged deprivation can still lead to cell death and tissue damage. The exact time frame can vary depending on the specific tissue, underlying health conditions, and individual factors.

What happens when an animal is deprived of oxygen?
When an animal is deprived of oxygen, their body will be unable to produce energy through aerobic respiration, leading to cell damage and potentially death if oxygen deprivation lasts for too long. Without oxygen, the brain is particularly vulnerable, and lack of oxygen can result in irreversible brain damage within minutes. The body will try to compensate by increasing heart rate and trying to take in more oxygen, but prolonged deprivation will eventually lead to organ failure.
Why is the lack if of oxygen in the brain cell able to cause death?
A lack of oxygen in brain cells (hypoxia) can lead to cell damage and death due to the brain's high energy demands and sensitivity to oxygen deprivation. Without oxygen, brain cells are unable to produce energy through aerobic respiration, leading to cell dysfunction and ultimately cell death, which can result in neurological deficits or death.
What is happening to the genetic material just before a cell leaves interphase and starts prophase of cell division?
replicating
How long can the heart muscle be deprived of adequate oxygen supply?
The heart muscle can only withstand a few minutes of inadequate oxygen supply before damage begins to occur. Prolonged deprivation of oxygen can rapidly lead to irreparable damage and cell death in the heart muscle, resulting in a heart attack. Immediate medical attention is crucial to restore blood flow and prevent long-term complications.
What role did diffusion play in the changes you observed?
Before diffusion there is a higher concentration of oxygen molecules outside the cell than inside the cell. After diffusion the concentration of oxygen molecules is the same outside and inside the cell.
Before mitosis begins which happens before the nucleus starts dividing?
During interphase, which precedes mitosis, the cell grows and replicates its DNA in the nucleus. This prepares the cell for division by ensuring that each daughter cell receives a complete set of genetic material.
In meiosis, the replicating cell starts as a what?
In meiosis, the replicating cell starts as a diploid cell.
When you lose oxygen what happened?
When you lose oxygen, your body is deprived of a critical component needed for cellular respiration, which is the process by which cells generate energy. This can lead to oxygen deprivation in tissues and organs, disrupting their normal function and potentially causing damage or even cell death. Symptoms of oxygen deprivation include shortness of breath, confusion, dizziness, and loss of consciousness.
Skin cell that die due to lack of blood flow?
Skin cells that die due to lack of blood flow are typically keratinocytes. Keratinocytes are the most abundant type of skin cell and are responsible for producing the protein keratin, which provides the skin with strength and elasticity. When deprived of blood flow, keratinocytes can undergo apoptosis (cell death) due to a lack of oxygen and nutrients.
What would happen to tissues or organs derived of oxygen for a long time?
Tissues and organs that are deprived of oxygen for a long time can undergo cell death, leading to tissue damage or organ failure. This lack of oxygen, known as hypoxia, can impair the normal function of cells and tissues, ultimately causing them to deteriorate and potentially die.
