Population Genetics is the study of genetic events at the level of the population. Below is a handout which will help you understand population genetics better. http://www.bio.miami.edu/dana/250/25009_16print.html.

Electron transport system

admin Theory

Embedded in the inner membrane of the mitochondrion are a bunch of protein complexes that are involved in electron transport. They make up the electron transport chain (ETC). HERE you will find an amazing website VIRTUAL CELL ANIMATION COLLECTION. Take a look at an electron transport chain (ETC). HERE there is another good video about ETC in mitochondria. Useful animations …

Amino Acids & Proteins

admin Theory

For the hardest part in biology olympiads has always been biochemistry. Thus, I would like you to be the best in this field, so here you will find some good notes of amino acids and proteins from the biochemical point of view.Especially pay your attention to isoelectric point and pK calculations. The isoelectric point, sometimes abbreviated to IEP, is the …

Review a concise and fun slideshow about enzymes before olympiad below. http://rvrhs.enschool.org/ourpages/auto/2013/10/8/45710277/Enzyme%20Notes%201-22.pdf

Behavioral ecology

admin Solving problems

This lesson is about behavioral ecology. Behavioral ecology is the study of the evolutionary basis for animal behavior due to ecological pressures.  Most probably during olympiad you will get a situation and you will have to determine what kind of behavior is in the problem. For example,                   The answer is B …

Biostatistics Part 2

admin Solving problems

To continue our topic on biostatistics, here I will post some good stuff to learn. Firstly, HERE you will find amazing tutorial. Take a look. Below you will find a simple introduction to chi-square. http://www.dpisd.org/cms/lib4/TX01001079/Centricity/Domain/1059/ChiSquarePractice.pdf http://staff.orecity.k12.or.us/kate.fisher/Ms._Fishers_Website/AP_Biology_files/X2%20Practice%20Problems%20Key.pdf https://sharepoint.ocsarts.net/student/academic/rima_semaan/honors_biology/Lists/Announcements/Attachments/422/Ch%2011%20Genetics%20and%20Statistics%20(Chi%20Square).pdf  http://www.colby.edu/biology/bi164/Lab/Lab%204Genetics&ChisquareANSWERKEY.pdf

Biostatistics Part 1

admin Solving problems

After some break, I came back and would like to suggest you reading about biostatistics. Even though in biology olympiads this comprises only a small part of testing, however, you should know t-test and Chi-square very very well. To begin with, bellow you will find a comprehensive textbook of biological statistics. http://udel.edu/~mcdonald/HandbookBioStat.pdf, A good summarize on P-VALUES AND HYPOTHESIS TESTING. …

Enzyme kinetics

admin Theory

Here you will find some stuff about enzyme kinetics. The study of the rate at which an enzyme works is called enzyme kinetics. http://web.campbell.edu/faculty/chazotte/  http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/E/EnzymeKinetics.html http://www.columbia.edu/itc/chemistry/chem-c2407/hw/ENZYME_KINETICS.pdf www.glutxi.umassmed.edu/grad/GradKinetics.pdf  

pH changes

Titration curves

admin Theory

If you have already read about buffers in Theory section, it’s time to learn a bit about titration curves. www.chemguide.co.uk/physical/questions/q-phcurves.pdf http://www.learningace.com/doc/5727008/923a81c3eda76a1b3179eb8bd9f2d01d/4124lab2

Buffers

admin Theory

Here you will find theoretical material about buffers. According to Wikipedia, a buffer (more precisely, pH buffer or hydrogen ion buffer) is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Its pH changes very little when a small amount of strong acid or base is added to it and thus …

Dicot and monoct root anatomy

admin Plant biology

Below you will find some notes with cross sections of dicot and monocot roots. Quite often you may be asked to make a cross section and view it under the microscope during olympiad and then answer the questions associated with your sample. http://teacher.sanjuan.edu/webpages/dkaragianes/files/dicot_monoct_root_anatomy.pdf

Buffer Practice Problems

admin Solving problems

Bellow you will find some buffer problems. Before start read about buffers in Theory section.  http://www.biochem.arizona.edu/classes/bioc462/ Another one problem set is bellow: http://personal.denison.edu/~kuhlman/courses/biochem/samples/aqueous_eq_buffers.pdf.
