Answer and Explanation:
An acid has a pH that is less than 7.  A base has a pH that is greater than 7.  Something that has a pH of 7 is neutral, but since it doesn't seem that the question is asking about neutral, you can ignore that for this problem.
Situation 1:   Base
Situation 2:  Acid
Situation 3:  Acid
Situation 4:  Base
Situation 5:  Acid
Situation 6:  Base
A.  Water directly out of the tap has a pH of 7.2.  When you add carbon dioxide (blow into the water), you get a pH of 5.1.  This means that the addition of carbon dioxide makes water more acidic.
B.  The most basic solution will have the highest pH.  This means that it will be water with bleach added to it.
C.  The most acidic solution will have the lowest pH.  This means that it will be water with instant coffee.
 
        
             
        
        
        
Explanation:
The function of the cell membrane is to protect the organelles that break down proteins and nutrients. 
It is semi-permeable which means it takes in select nutrients and excretes cell waste into the bloodstream. 
 
        
             
        
        
        
Leptin  hormone  is  the  hormones  which  appears  to  be   designed  to  protect  the  body  against  weight  loss.
    Leptin  hormone  is  secreted   from  fat  cells  and  it  helps  to  regulate  body  weight.  Leptin  hormone   is  predominantly made  by  adipose  cell that    help  to  regulate  energy  balance   by inhibiting  hunger. leptin  hormone  is opposed  by  the  action  of  the  ghrelin  hormone which  is  a  hunger  hormone/
        
             
        
        
        
The ATP enables the movement of transport proteins to move the ions across a cell membrane by its getting fueled by its hydrolysis 
<u>Explanation:</u>
The plasma membrane is a semi permeable membrane that is the movement of molecules across the membrane is constricted. There are 2 types of moment across the plasma membrane one is the active transport and the other is the passive transport. The active transport involves the help of ATP whereas the passive transport does not involve ATP to transport the materials.
 
        
             
        
        
        
Resource allocation includes managing tangible assets such as hardware to make the best use of softer assets such as human capital. Resource allocation involves balancing competing needs and priorities and determining the most effective course of action in order to maximize the effective use of limited resources and gain the best return on investment.
