Answer:
The answer to your question is 75%
Explanation:
Data
Theoretical production = 4 moles
Experimental production = 3 moles
Percent yield = ?
Formula
![Percent yield = \frac{Experimental production}{Theoretical production} x 100](https://tex.z-dn.net/?f=Percent%20yield%20%3D%20%5Cfrac%7BExperimental%20production%7D%7BTheoretical%20production%7D%20x%20100)
Substitution
![Percent yield = \frac{3}{4} x 100](https://tex.z-dn.net/?f=Percent%20yield%20%3D%20%5Cfrac%7B3%7D%7B4%7D%20x%20100)
Result
Percent yield = 75 %
The correct answer would be, "<span>D. beta-galactosidase".
As all the others are made in different organisms.

<u>We are given:</u>
Mass of Na added = 4.35 grams
Mass of water = 105 grams
<u>Mass Percent of Na:</u>
Total mass of the solution = mass of solute + mass of solvent
Total mass of the solution = 4.35 + 105 = 109.35 grams
Mass percent of solute = (mass of solute / mass of solution) * 100
Mass percent of Solute = (4.35 / 109.35) * 100
Mass percent = 3.978 %
Exposure to small amounts of lead<span> over a long period of time is called chronic toxicity. </span>Lead<span> is particularly </span>dangerous<span> because once it gets into a person's system, it is distributed throughout the body just like helpful minerals such as iron, calcium, and zinc. And </span>lead<span> can cause harm wherever it lands in the body.</span>
Answer:
answer is a because drugs do so to the person.
