W is wrong. It represents a vacuole, which can store both nutrients and waste products for later elimination.

Y is wrong. It represents the nucleolus, which plays a critical role in the synthesis of ribosomes.  

Z is wrong. It represents the cytoplasm, which is where cell processes like glycolysis and protein synthesis take place.

If you overshoot the endpoint in titration of the KHP, how would the calculated value for the molarity of the NaOH solution be a
Greeley [361]
<span>If you overshoot the endpoint in titration of the KHP, an error will happen in your calculations for the molarity of NaOH you are standardizing. For this, a neutralzation reaction happens where amount of acid should be equal to amount of base. Adding more of the base needed to reach the equivalence would mean you have higher volume which will make the calculated concentration of NaOH lesser.</span>
