“If I have seen further, it is by standing on the shoulders of Giants.”
--Sir Isaac Newton, writing to his fellow scientist Robert Hooke in the winter of 1675
There’s something about owls, now flitting about the barren woods of February, that sets philosophers to
philosophizing about knowledge and the like.
Maybe it’s the birds’ distinctive questioning—hoo, hoo?
Ancient Romans considered their Minerva, goddess of wisdom, to have appeared in the form of an owl.
century philosopher Georg Wilhelm Friedrich Hegel wrote of “the owl of Minerva that spreads its wings only with the
falling of the dusk.”
Henry David Thoreau wrote in his “Walden,” “I rejoice that there are owls.
Let them do the idiotic and maniacal
hooting for men.
It is a sound admirably suited to swamps and twilight woods which no day illustrates, suggesting a
vast and underdeveloped nature which men have yet to penetrate.”
The barred owl is the most common of our night stalkers, a year-round resident of Southern swamps and river
Because these are late-winter nesters, the young are ready and waiting in the spring for emerging rodents,
snakes, and insects.
Were it not for the skills of these birds of the dusk, we’d soon be up to our knees in rodents.
Unlike philosophers, this prowler of the night is more often heard than seen.
Its soft but penetrating querying “hoo,
hoo,” repeated several times, identifies it as it issues its territorial warnings.
As with most of their kin, barred owls
are silent hunters, flying noiselessly, depending upon night-adapted eyesight and noise-grabbing ears as they scan
the forest floor for their next meal—a meal suitable for a woodsy philosopher.
Each of us ultimately is responsible only to ourselves.
We ask you to do your own work on this quiz, and therefore to
be faithful both to yourself and to the university pledge you have affirmed.
For each question, select the one response that makes the most biological sense, & “bubble in” the letter
corresponding to the best response on your op scan sheet, using a #2 pencil (pencils & erasers are at the front).
Also, “bubble in” your name in the appropriate spaces.
Note: a = True & b = False
You may keep this sheet.
a. amino acid
All of these are correct.
The pH of an aqueous solution is a function of the ___________ion concentration of that solution.
