Answer:
Volume
Explanation:
The boiling point and density of water never changes, no matter how much you add
So the answer CAN'T be Boiling point or Density
Electrical Conductivity changes <em>only when the number of ions in a solution changes</em>
So it CAN'T be Electrical Conductivity
It has to be VOLUME because volume is the only physical property that changes when you add or take away liquid from a liquidous mixture

Explanation:
Letter to the editor,
Dear sir,
Never before in the history of this once proud and united country have elections divided this country in two. As the Democratic Party´s disagreement over the oficial party policy on slavery very clearly shows (with a Southern Democratic candidate and a 'normal' Democratic one), the deeply felt ideological split between the Northern and the Southern States has now, although Abraham Lincoln is chosen as the President, become a fact. This means that we, the United States of America, are no longer United.
 
        
             
        
        
        
Answer:
c) expression of genes and production of  specific proteins.
Explanation:
Estrogen is a lipid-soluble steroid hormone that diffuses through the lipid bilayer of the plasma membrane of its target cell. The hormone binds to its nuclear receptor and receptor-hormone complex then alters the expression of particular genes. 
It triggers transcription of specific DNA sequences into mRNA which in turn enters the cytoplasm and serves as a template for synthesis of specific proteins.
Estrogen is the female sex hormone and stimulates development of secondary sexual characters in females as well as required for maturation of egg. 
 
        
             
        
        
        
Answer: helps cool the body
removes waste chemicals through pores in the skin
Explanation:
Perspiration is a natural biological process that occurs in an mammals including human beings. Perspiration is required to maintain the homeostasis of the body. Homeostasis is the condition of maintenance of stable internal environment of the body with respect to the changes occurring in the external environment. Perspiration is also called as sweating when the body is exposed to heat it secrete sweat in order to provide coolness to the body. As the sweat contents are evaporated in the exposure of air. The sweat contents are emerge out by the pores present on the skin surface. The sweat consists of chemicals like aminoacids, salts and excess of water. Therefore, sweat removes the waste chemicals through the pores of the skin.
