The FINAL GRADES for BIO161 have been posted on the course page. Please review your grades and bring any problems to my attention before Saturday, when I will be posting them on Eservices. After they are posted to the system it is much harder to make corrections.
The FINAL GRADES for BIO220 have been posted on the course page. Please review your grades and bring any problems to my attention before Saturday, when I will be posting them on Eservices. After they are posted to the system it is much harder to make corrections.
The following are the penultimate grades for BIO161. The grades account for all drops and the final (so your grade seems lower than you think, it assumes a 0 for the final right now). Please go over these for any mistakes so they can be corrected.
The fourth exam was graded. The curve was +12%.
The posted grades now account for the dropped exam and have the Unknown and Presentation grades calculated in. In other words, this is as low as your grade can go.
The grades for Pre-E5 in BIO161 are here. This reflects a dropped lab and two of three dropped quizzes.
The lab quiz will focus on the major anatomy of the dissections and the major features of the jarred organismal groups.
My son Zachary has a 104 fever and therefore cannot go to daycare tomorrow. We will not have class tomorrow, but we should be okay. Please read chapters 14 and 15, focusing on the vocabulary and I’ll hit the key concepts when I come back. The assignment for the presentation should be submitted electronically if possible, but can be submitted in person on Wednesday if need be, but you probably won’t get to go the first day of presentations then.
Due to a variety of reasons both personal and professional, I have not completed the exams yet. I will be returning them on Tuesday next week.
You do have a quiz today, I would look at the first four sections of Chapter 35.
I’m sorry, but I have to be a bit snarky at this point. We have three weeks left and still people are emailing me the day before an assignment is due. I would cry but it is just too depressing.
For one more time, because I mentioned this during the lab and the class on Monday afternoon, the number column in the database is irrelevant. Those were the ID numbers in a previous semester. The other columns are tests that can be done. Yes, we haven’t done them all, but you can still use the data (you will be doing the remaining ones tomorrow) to determine a dichotomous key. Each step of a key is a simple yes/no construct where you are eliminating possibilities until you have only on possible outcome in each branch.
I have decided to have a little fun with the cladogram on the exam tomorrow. Instead of having you work with the clade names (i.e. phyla names), I’ll give you specific organisms and have you populate the cladogram from those.
Moo ha ha…
I thought I would post a few videos that deal with the specifics of parasitic worms and their interactions with their hosts.
This video (Youtube) details the lifecycle of a fish tapeworm and its interactions with the predator of the fish.
This video (Youtube) has a live tapeworm during a colonoscopy. Unlike many genera of tapeworms, this particular genus has some movement ability.
This video (Youtube) demonstrates live pinworms. I included this one mainly for a way to show relative size of these worms (note, Youtube considers this one scary or something, so you might need to sign in).
This video is a little disturbing, the removal of a 20 cm worm from an eye.
