Q4 LT1 Scores


Third Quarter Perio Scores

The exam was more difficult but most of you did well. I hope to be able to post a tentative grade by next week (you too, STR folks!). In the meantime, be content with what you’ve accomplished and try to enjoy the Christmas season! 🙂
Third Quarter Perio Scores

Third Quarter Perio

The Bio Perio is the last exam for the year. It is scheduled for Thursday, December 18, after Math. The test types and number of items are the same as last quarter’s Perio.  Study smart!


  • Osmoregulation and Excretion
    • osmoregulation in lower forms and in vertebrates
    • types of N-wastes
    • excretion in lower forms and vertebrates
    • the human excretory system
    • nephron anatomy and urine formation
    • hormones and the human kidney
  • Thermoregulation and the Integumentary System
    • heat exchange processes
    • adaptations for thermoregulation of endo- and ectotherms
    • functions and structures in the skin
  • Musculoskeletal System
    • musculoskeletal system of lower forms
    • functions of the musculoskeletal system
    • parts of the human skeleton
    • types of bones and joints
    • methods of bone formation/ossification
    • kinds of muscles
    • muscle organization (bundles within bundles)
    • muscle contraction and the sliding filament theory
    • types of twitches (Rb, please read this link or the appropriate section in your book)
    • the all-or-none response

Review by hunting for the old presentations, reading the books, and visiting this online textbook for more clarifications.

Bio notebooks are required for those with grades lower than 1.75. EOQR’s are for everyone (look for them in previous posts, just answer the first 4 questions). Due to insistent public demand, I will have another optional reci activity for those who may opt to complete it (to be posted later). I will leave trays in the exam rooms of Cs and Rb. Please make sure your notes, etc. are in it by 1030 AM on Dec 18.

Good luck and God bless!

2nd Quarter Perio Scores

Yes, it was tough. Congrats to those of you who got grades higher than expected.

Feel free to visit me any time this week to see your exam papers and debate your scores. 😉 Grades will be out (hopefully) by this weekend. Keep tuned!

ERRATUM: The following class numbers have +1 (considered number) to their total score – Rb17, 19, 25, 26, 28 and Cs2, 7, 10, 11, 14, 20, 24, and 25.

Cs and Rb LT2 Results

Study well for the Periodic Exams. It has more items than last quarter’s and is not solely multiple choice. o_0  Perio will cover all LT1 and LT2 topics.

Those with grades below 1.75 are required to submit notebooks on the Bio Perio day (Thursday) at 1030AM outside the Bio Unit. Everyone is required to submit EOQ Reflections. Those who are not submitting their notebooks can write their EOQR’s on a sheet of paper.

  1. What was your favorite topic this quarter?
  2. Which misconceptions were corrected?
  3. What questions do you have regarding the topics discussed?
  4. What concepts were you able to apply?

I am free in the afternoons for consultation. Please feel free to consult with me, esp. for those who have grades of 2.50 and below.

LT2 pointers and review resources

  1. Vertebrate respiration and breathing
  2. Control centers that regulate breathing
  3. Gas exchange and pressure gradients
  4. Respiratory pigments
  5. Adaptations of deep-diving mammals
  6. Pathogens and disease
  7. Three major lines of defense
  8. Specific vs. non-specific immunity
  9. Active and passive immunity
  10. Artificial and natural immunity

Presentations can be downloaded from earlier posts.

Other resources:

  1. Cell-mediated immunity (swf)
  2. Humoral immunity (swf)
  3. Antibody action (wmv)

Cs and Rb Results for LT2 and Q+LT Totals

LT 2 was generally tougher than LT1. Congratulations to those of you who made it! This table shows your totals for Quizzes and Long Tests which amounts to 35% of your grade. Please note that I haven’t factored in the + 1 for the first long test yet (for Rb) and the corrections for the second long test (+1 for Josh and Mica).

Aiming for a better grade? Don’t lose hope! Your lab acts and class activities are worth 20% so if you’ve submitted the pre-lab, good output for lab acts, concept map, and the food calorie exercise, you’ll have a good grade in this component.

Don’t forget class participation: 8% for the reci points, 8% for the HW, and 4% for the notebook grade. You can still get a perfect score for the end-of-quarter check (NB’s due at 10:30AM on July 29 at rm 111) by doing the following:

  • making sure you have complete notes
  • answering the EOQ reflections
  1. What was your favorite topic this quarter?
  2. Which misconceptions were corrected?
  3. What questions do you have regarding the topics discussed?
  4. What concepts were you able to apply?
  5. Do you have any comments or suggestions?
  • submitting your envelope with checked quizzes and LT’s and your parents’ signatures
  • including your copy of the course outline in your notebooks

The perio is coming up (T, 910-1010 AM). This is 25% of the grade and is a multiple choice exam. The bulk of the perio is on digestion and transport with a good number of items on tissues and the evolution of multicellularity. Don’t forget to review the levels of biological organization. Again, the coverage will only be until the heart design in vertebrates.

Comment on this entry for any questions or clarifications. Good luck and God bless! 🙂
