Sub mucosa one Laryer trachea expect

Goblet cells are considered to be one type of region

The tool that use in extraction is called

Salting out process is lead to increasing in the polarity of solution that result the decreasing .in the solubility a non-polar compound

Should have the solvent that use inthe extraction process _______ boiling point😌

The solvent that has less density should be in the down layer

What is the use of ether layer?

The water has density more than of ether

Should have the solvent that use in the extraction process a low boiling point :because

Combound soluble in the ether, water
