A zone of tissue injury is called?
a lesion
What is the difference between lysis and plasmolysis?
When a cell is placed in a hypotonic solution, water will enter the cell. This is called lysis. When a cell is placed in a hypertonic solution, water will leave the cell (causing it to shrink). This is called plasmolysis.
At what point in the reproductive cycle of the T4 bacteriophage is host cell infection irreversible?
Once the T4 bacteriophage injects its genetic material into the host cell, infection becomes irreversible. This usually occurs as soon as the phage's tail fibers attach and the genome is injected, initiating the takeover of the host cell machinery for viral replication.
Distinguish between reversible and irreversible electrochemical cell?
irreversible cells are those which require replacement of chemicals.when they give out electricity. these cannot be recharged. examples are : 1 =dry cell 2=zinc acid copper cell reversible cells are those in which reversible reactions are involved.these cells can brought back to their initial state by applying external potential difference
What would happen if ribosomes suddenly stopped working in a cell?
If ribosomes suddenly stopped working in a cell, protein synthesis would be disrupted, leading to a decrease in the production of essential proteins. This could result in cell dysfunction, impaired growth, and ultimately cell death.
A zone of tissue injury is called?
a lesion
What is cell injury and cell death?
Cell injury refers to any damage or disruption to a cell's structure or function caused by various insults. Cell death is the irreversible cessation of cellular activities and functions, leading to the demise of the cell. Cell death can occur through different mechanisms, including apoptosis and necrosis.
What is primary and secodary cell in term of physics?
a primary cell is an electric cell that produces current by an irreversible chemical reaction
What is galvanic cell?
A galvanic cell is an electric cell that generates an electromotive force by an irreversible conversion of chemical to electrical energy.
What is the pathogenesis of necrosis?
In normal cell the inter acellular calcium concentration is about 0.001 that of extra cellular fluid . This gradient is maintained by the cell membrane which actively transports ca ions out of the cell . Irreversible injury causes accumulation of ca ions in cell . Ca activates endonucleases ( hydrolysis DNA ) phospholipases ( disrupt membranes ) and proteases ( digest the cytoskeleton ) .
What are the factors of cell injury?
Cell injury can be caused by various factors, including physical agents (like trauma or temperature extremes), chemical agents (such as toxins or drugs), biological agents (like bacteria and viruses), and nutritional imbalances (deficiencies or excesses). Additionally, hypoxia (lack of oxygen) and immune responses can contribute to cellular damage. The severity and duration of the injurious stimuli, as well as the cell type and its adaptive capabilities, play crucial roles in the extent of injury. Ultimately, these factors can lead to reversible or irreversible cell damage, depending on the circumstances.
What point in the reproductive cycle of the T4 bacteriophage is host cell infection irreversible?
Once the viral DNA is duplicated in the cell.
Which cell process will be stopped?
osmosis

What is an irreversible process during which the cell degenerates and the nucleus may become fragmented and protein denature?
Necrosis
Is corrosion is a reversible cell reaction or irreversible cell reaction?
Corrosion is typically considered an irreversible cell reaction. It involves the degradation or deterioration of a material due to chemical or electrochemical reactions with its surroundings, leading to a loss of material and structural integrity. Once corrosion occurs, it is difficult to reverse the process completely.
