Answer:
Answer is Ammonium sulfate.
Explanation:
The method of adding ammonium sulfate to a protein solution is known as precipitation. This is because the addition of ammonium sulfate will reduce or decrease the solubility of the protein. And as the ammonium sulfate is being increased, so also the solubility of the protein will be decreasing.
And at the long run, the protein will be precipitated. This is what is referred to as the 'salting out' procedure.

The right answer is C.
Synovia is a viscous biological fluid located at the joints and fulfilling several functions. It limits bone friction between them, dampens shocks, provides the nutrients and dioxygen necessary for chondrocytes (cartilage cells) while eliminating their metabolic waste, and benefits from the presence of immune cells to eliminate possible body foreigners.
 
        
             
        
        
        
Answer:
Interphase
Explanation:
Eukaryotic cells have two parts of the cell cycle: Interphase and mitotic phase. It is the interphase in which a cell typically spends most of its time. During interphase, a cell grows and carries out the metabolic activities for regular growth and maintenance.
