Answer: The correct answer for the fill in the blank is Negative.

There are three subatomic particles of an atom that are electron ( negatively charged), proton ( positively charged), and neutron ( with no charge). This means that electron is a negatively charged ion.

If an atom gains an electron, it means that there is an increase in its negative charge.

Thus, the atom has a negative charge.

A student observes 5,000 RFUs in a 200μl aliquot from a G3-500 ml culture. How many total RFUs will be present in a G3-15ml samp

Answer:

The maximum no. of RFUs collected in the purification procedure $= 3.05 \times 10^5$ RFUs

Explanation:

No. of RFUs in a 200 ul (0.2ml) aliquot = 5000 RFUs

So, No. of RFUs in G3-500 ml culture $= 5000 \times \frac{500 ml}{0.2 ml}$ RFUs

$= 5000 \times 2500$ RFUs

$= 1.25 \times 10^7$ RFUs

Similarly, No. of RFUs in a G3-15ml sample $= 5000 \times \frac{15 ml}{0.2 ml}$ RFUs

$= 5000 \times 75$ RFUs

$= 3.75 \times 10^5$ RFUs

The maximum no. of RFUs collected in the purification procedure

$= 3.75 \times 10^5 \times 80$ % RFUs

$= 3.75 \times 10^5 \times 0.80$ RFUs

$= 3.05 \times 10^5$ RFUs
