The typical ratio for fixative volume to tissue is 10:1, meaning 10 times the volume of fixative compared to the volume of the tissue. This ensures proper fixation and preservation of the tissue structure for further analysis. Adjustments to this ratio may be needed depending on the tissue size and fixative used.

How does Carnoy's solution act?
Carnoy's solution is a fixative creating covalent chemical bonds between proteins in tissue. Most commonly used fixative in histology is formaldehyde. It prevents decay.
What is an unfixed tissue?
Unfixed tissue refers to biological samples that have not been treated with a fixative to preserve their cellular structure. Unfixed tissue is more prone to degradation and changes over time compared to fixed tissue. It is typically used for special analyses or research purposes that require fresh tissue samples.
What is the formula for void ratio?
Void ratio (e) is typically defined as the ratio of the volume of voids to the volume of solids in a soil sample. The formula for void ratio is e = Vv/Vs, where Vv is the volume of voids and Vs is the volume of solids in the soil sample.
Does changing the volume of a particular substance change its mass to volume ratio?
No, changing the volume of a substance does not alter its mass to volume ratio. The mass to volume ratio, also known as density, remains constant regardless of the volume of the substance. Density is a physical property that is intrinsic to the material and is not affected by changes in volume.
Calculate volume flow rate?
This is the ratio volume/time.
What is the primary purpose of a fixative?
To kill the tissue so that post mortem decay is prevented

A ratio between mass and volume?
The ratio between mass and volume is density.
What is Carnoy's fixative?
Carnoy's fixative is a solution used in histology to preserve tissue samples for microscopy. It is a mixture of ethanol, chloroform, and acetic acid that helps to prevent decay and maintain the structural integrity of cells. Carnoy's fixative is particularly useful for preserving certain structures like chromosomes.

What is the ratio of mass to volume called?
DensityThe ratio of mass to volume is density.

Is picric acid a dye or fixative?
Picric acid is primarily used as a fixative in histology to preserve tissue specimens for microscopy. It is not commonly used as a dye in the same way that other chemicals like hematoxylin and eosin are used to stain tissues for visualization.
How can you find a cell's survace area to volume ratio?
to obtain the ratio of surface area to volume, divide the surface area by the volume.
Density is the ratio of?
Density is the ratio of mass to volume.
What is the formula for void ratio?
Void ratio (e) is typically defined as the ratio of the volume of voids to the volume of solids in a soil sample. The formula for void ratio is e = Vv/Vs, where Vv is the volume of voids and Vs is the volume of solids in the soil sample.
What is the relationship between edge length ratios area ratios and volume ratios of similar figures with various scale factors?
Area ratio = (edge-length ratio)2 Volume ratio = (edge-length ratio)3 Volume ratio = (area ratio)3/2
