Why will the segment of lung tissue cut from the fetal pig sink when placed in water?
Healthy lung tissue from an adult pig will float in formalin because there is a (relatively) large volume of air trapped in the alveolar sacs. Fetal pigs haven't taken a breath yet, so there is no air in the alveolar sacs. This is why the lung tissue from a fetal pig will sink in formalin.
Incidently, this is also how medical examiners can determine if a child was stillborn or was born alive and then died - check to see if a section of lung from autopsy floats in the formalin.
What else can I help you with?
Do tissue float?
Tissue does not float in water. Tissue is denser than water, so it will sink when placed in water.

Does the piece of lungs tissue float or sink in water?

What is the direction of water movement in a cylinder of potato tissue in distilled water?
In a cylinder of potato tissue placed in distilled water, the direction of water movement will be from the external solution (distilled water) into the potato tissue due to osmosis. This is because the potato cells have a higher solute concentration compared to the external solution, resulting in water moving into the cells to equalize the concentration gradient.

Tissue is a weak solid.
Why should cold water not be placed on a burn?
Cold water can cause further damage to the burn by slowing down the healing process and potentially damaging the skin tissue further. Using cool running water is recommended instead to help reduce pain and inflammation.
Is a cell is placed in a salt water water leaves cell by?
If a cell is placed in salt water, water leaves the cell by osmosis.
If a cell is placed in salt water water leaves the cell by .?
If a cell is placed in salt water, water leaves the cell by osmosis.
Does a tissue float in water?
Yes, a tissue will typically float in water because it is less dense than water. The air trapped inside the tissue fibers makes it buoyant enough to float on the surface of the water.
What is the main excretory organ in a fetal pig?
The main excretory organ in a fetal pig are the kidneys. The kidneys are responsible for maintaining water levels and excreting waste matter from the blood.
Why does lipids have to be placed in alcohol first before being placed water?
