True, moving genes from a chromosome of one organism to a chromosome of a different organism.
Answer:
Percentage of an aldrin in the sample is 44.41%.
Explanation:

Molarity of the silver nitrate solution = 0.03337 M
Volume of the silver nitrate = 23.28 mL = 0.02328 L
Moles of silver nitrate = n

n = 
According to reaction 1 mole of silver nitrate recats with 1 moles of chloride ions.
Then 0.0007768 moles of silver nitrate will react with:
chloride ions.
In one mole of aldrin there are 6 moles of chloride ions.
Then moles of aldrin containing 0.0007768 moles chloride ions are:

Moles of aldrin present in the sample = 0.0001295 mol
Mass of 0.0001295 moles of aldrin present in the sample :
0.0001295 mol × 364.92 g/mol =0.04726 g
Percentage of an aldrin in the sample:

Volume of carbon dioxide absorbed = 33.6 L ≈ 34 L
Explanation:
We have the following chemical reaction:
CO₂ (g) + 2 LiOH (s) → Li₂CO₃ (s) + H₂O (l)
Now we devise the following reasoning:
if 1 mole of carbon dioxide reacts with 2 moles of lithium hydroxide
then X moles of carbon dioxide reacts with 3 moles of lithium hydroxide
X = (1 × 3) / 2 = 3/2 moles of carbon dioxide
And we calculate the volume of carbon dioxide using the following formula:
number of moles = volume / 22.4
volume = number of moles × 22.4
note: units for 22.4 are "L / mole"
volume of carbon dioxide = (3/2) × 22.4 = 33.6 L ≈ 34 L
