Peregrine falcons have a wide diet, including many types of smaller birds. These birds eat bugs like grasshoppers. So, if the grasshopper population decreases, then the birds who are a food source to peregrine falcons will also have a lower population. This means that there is a lesser amount of food for the peregrine falcons to eat, so their population will decrease as well. 
Good luck with your problems!
        
             
        
        
        
Answer:
The correct answer is option 4.  Parasympathetic division.
Explanation:
The parasympathetic division is one of the three divisions of the ANS or autonomic nervous system. It also helps in the rest system or digest system as it saves energy by slowing the heart pace by slowing the rate of contraction. This is performed with the help of nerve fibers that send signals.
Parasympathetic nerve division increases the intestinal and activity gland. This nerve division helps in relaxing the sphincter muscle in the GI tract.
Thus, the correct answer is option D.
 
        
             
        
        
        
Answer:
4.2moles
Explanation:
"The answer to your question is 4.2 moles of H₂O
Explanation:
Data
moles of H₂O = ?
moles of C₂H₆ = 1.4
Balanced chemical reaction
 2C₂H₆ + 7O₂ ⇒ 4CO₂ + 6H₂O
Process
To determine the moles of H₂O, use proportions and the coefficients of the balanced chemical reaction.
 2 moles of C₂H₆ 6 moles of H₂O
 1.4 moles of C₂H₆ x
 x = (1.4 x 6) / 2
 x = 8.4/2
 x = 4.2 moles of H₂O"
