Exercise 2C: Cell Divison
Reminder:
Your exam is on August 15‐19 (depending on the schedule of your respective lab classes)
Hindi lang ito ang aaralin nyo ah! These illustrations are just to compensate for your abstract
drawings, mas mapapadali na ang aral niyo! Study everything! Exercises 1‐4, everything in your lab
manuals, worksheets and notes may be included in your exam. Be reminded to come 1 hour after the
start of class (meaning, if your class is from 4‐7 come at 5pm for your exam) bring a bluebook and
come prepared. Know all the techniques and all the theoretical stuff, study and you’ll be fine, don’t
study.. and ewan ko lang :p haha. Galingan niyo!
PS Midterm standings will also be released after your first lab exam
