“Bloomifying”
MC question: Licking a newt is a bad
idea for which of the following reasons
Steve Jurvetson CCL Attribution 2.0
Licking a newt is a bad idea for which
of the following reasons:
a) Newts are similar to cacti: they have tiny
spines on their skin.
b) A little known fact about newts is that if you
lick them, they will follow you around for one
year.
c) Newts secrete a neurotoxin called
tetrodotoxin, the same toxin found in puffer
fish.
d) Newt skin contains lead, a neurotoxin.
Disclaimer: I am a physicist, not a biologist. My apologies if I’m a little off on any of the biology!
Can we “Bloomify” it up to the Apply
Level?

“Bloomified” Question
1. Examine this graph of newt
toxicity levels in four Oregon lakes.
Which of the following statements
are likely to have caused toxicity
differences between Crater Lake and
Soap Creek newts?
a) Crater Lake newts currently have
fewer predators and/or a less
abundant food supply than Soap
Creek newts
b) In the past, Crater Lake newts
had fewer predators and/or a
less abundant food supply than
Soap Creek newts
c) Both a) and b)
Seeking Feedback From Colleagues
Excerpt from an email that I received from biologist colleague Cynthia
Brame:
If you ask a more knowledgeable student, who either doesn't know the context of the
class or is a worrywort (they do pop up...), then she starts thinking things like: "We can
turn expression of enzymes on and off relatively rapidly, and do so all the time. If the
predators are secreting a pheromone, it could act as a signaling molecule in this welladapted population such that it starts expressing the enzyme that makes TTX.
Alternatively, if the presence of the higher concentration of predators is causing
increased stress and this cortisol, a downstream effect could be increased expression of
the enzyme that makes TTX. ....but maybe since the teacher is giving "whole body TTX”,
she's looking for less of a targeted effect...I wonder what she wants me to say....”
So I guess I'm saying that it is a perfectly reasonable question for a novice who doesn't
know much about other fields of biology (e.g.,genetics or endocrinology), but maybe
stickier for students who have other knowledge to bring to the table.
Could you turn it around and tell the students about different environments and ask
which newt population is likely to have the lowest TTX? the fewest copies of a TTXproducing enzyme?
