Rankle #115 answer: estimated number of receptor cells (fewest to most)

The answer

Rank by estimated number of receptor cells (fewest to most)

1. 1Taste Buds (tongue)10,000 receptors
2. 2Hair Cells (ear)15,000 receptors
3. 3Olfactory Receptors (nose)6,000,000 receptors
4. 4Photoreceptors (eye)125,000,000 receptors

Why this order

Ranked fewest to most, Taste Buds (tongue) (10,000 receptors) goes at the top and Photoreceptors (eye) (125,000,000 receptors) at the bottom.

The closest call is Taste Buds (tongue) (10,000 receptors) against Hair Cells (ear) (15,000 receptors), about 50% apart. That is the swap most likely to cost a point.

The biggest gap is between Hair Cells (ear) and Olfactory Receptors (nose), about 400 times apart, so that boundary should be the easiest part of the order to get right.

From top to bottom the figures span a factor of roughly 12,000.

These are the figures the game reveals after you submit. They are rounded; only the order is scored.

Difficulty: medium, judged by how close the tightest pair is.
