AP and SAT II Biology (Photosynthesis)

I'd like to explain why these pages have been blank in the past few days.  Much of my blogexodus has been due to my passion to help educate, enlighten and entertain high-school students.  I've mentored and tutored students in the past, but lost focus due to time-constraints and other social obligations.  Since my environmental duress has lessen, I am now able to fully dedicate myself to my pedagogical work

So if I'm ignoring your gchat messages, it's not because I'm avoiding you, it's because I'm too busy making biology appealing to 16 year-olds.

What Trees and Fish have in common

Did you know fish have a specialized calcified bone called the otolith that let's you estimate how old your aquatic friend is?

Not only can you determine age, but researchers can also roughly determine which oceanic regions have been visited by the fish due to the accumulation of different mineral compositions.

When I was little, I used to  ask my parents how old the fishes in our tank were.  Now I have reason not to ask anymore.

However, looking at the otolith requires removing the head from the body.
