According to the escience lab manual for lab 1, experiment 3, you need to prepare a 47 mL of a 24% soda/syrup prescription. To do this, you can use the 80% syrup solution and the 10% soda solution that you have in stock. How many mLs of soda solution do you need to create this final solution?

Answers

Answer 1
Answer:

Answer:

33 mL  

Explanation:

It is important to recognize that the total amount of pure syrup remains constant:

Total syrup in the stock solution = total syrup in dilute solution

Thus, we can use the dilution formula

V₁c₁ = V₂c₂

Data:

V₁ = ?;          c₁ = 80 %  

V₂ = 47 mL; c₂ = 24 %

Calculations:

1. The volume of stock syrup

\begin{array}{rcl}V_(1)c_(1) & = & V_(2)c_(2)\nV_(1)*80 \, \% & = & \text{47 mL}* 24 \, \%\n80V_(1) & = & \text{1130 mL}\nV_(2)&=& \frac{\text{1130 mL}}{80}\n\n&=&\text{14 mL}\n\end{array}\n\text{You need $\textbf{14 mL}$ of stock syrup.}

2.  The volume of soda solution

Total volume of dilute solution =  47 mL

The volume of stock syrup        =  14

Volume of soda solution            = 33 mL

You need 33 mL of soda solution.

Which of the following would affect heart rate in a similar way to activation of the parasympathetic ANS? Group of answer choices a. Norepinephrine antagonists
b. Overexpression of norepinephrine receptors on cardiac muscle
c. Reduce AChR expression on the cardiac muscle
d. Increased nicotinic receptor expression on skeletal muscle Atropine

Answers

Norepinephrine antagonists would affect heart rate in a similar way to activation of the parasympathetic ANS.

Answer: Option A

Explanation:

Norepinephrine is responsible for increasing the rate of the heart and causes contraction of the muscles. Having an antagonist norepinephrine would act in the opposite way and would decrease the rate of the heart and help relax the body of the human.

It will act in a similar way to activation of parasympathetic ANS which is responsible for the decreasing the heart rate and increasing the digestion at a faster rate. It relaxes the body of the humans.
