The correct answer would be D. Mollusca.

The question is basically describing a snail.

Arthropoda have segmented bodies.

Echinodermata(starfishes, sand dollars etc.) are radially symmetrical.

Also none of them have shells except phylum Mollusca :)

Blizzard [7]

Answer:

46 * 10^7 pfu/ml

Explanation:

Given -

Bacteriophage dilution = 0.1 ml

Volume of bacteria and plate with top agar  = 0.3 ml

Number of plaques = 46 pfu

Dilution (d) = 10^{-6}

Final concentration of phage stock is equal to

= \frac{pfu}{d*v}

Where pfu is the count of plaques

d is the dilution and v is the volume

Substituting the given values, we get -

\frac{46}{10^{-6} * 10^{-1}} \\= 46 * 10^7 pfu/ml

If a researcher is interested in measuring both the structure and function of the brain, which technique might one recommend
Anettt [7]
The best method for studying both the structure and the function of the brain would be the functional magnetic resonance imaging (fMRI).
This technique measures the blood flow to different brain regions in order to determine which areas are active in certain brain processes. An increase in the blood flow increases the amount the oxygen the area is receiving that is needed for the functioning of the nerve cells.
