Your Investigation / Project

Click here to see some information about planning your project and some websites where you might find some ideas for project topics

This is a very useful resource to read about planning a Biology project -
http://www.prestwick.sayr.sch.uk/uploads/1/0/7/2/10727262/sserc_ah_investigation_guide.pdf

And when you are planning or even writing up your investigation, you may like to ask your teacher if they can give you a more detailed outline or marking scheme. This September 2016 marking scheme is available online at the SQA website and will give you an idea of what to look for - but maybe see if your teacher has a more up to date version:

Some extras just for revision from last year :
Prokaryotes / Eukaryotes
Interesting reference about prokaryotes, autotrophs, bacteria, staining bacteria, cyanobacteria, etc. and their evolution and how they relate to eukaryotes in evolutionary time :  (Not all of this content is in Advanced Higher but you might find it interesting to read anyway)
Prokayotes Link
A nice reminder of groups such as archaea, fungi, bacteria etc. :

Some interesting bits re proteins here - go to the heading "Proteins" !!
http://www.uic.edu/classes/bios/bios100/lectures/chemistry.htm

Two TED talks about proteins to watch - both interesting :
DNA
DNA has a negatively charged backbone due to the phosphates. This means it will attach to positively charged proteins such as histones eg in folding up of DNA into the nucleus. This is an excellent short animation showing this folding with histones and nucleosomes shown :
https://www.youtube.com/watch?v=gbSIBhFwQ4s

Experimentally setting up a gel electrophoresis :
Electrophoresis can be used to separate proteins etc.
https://www.youtube.com/watch?v=vq759wKCCUQ

Isoelectric electrophoresis
can be separated in one direction based on pH gradient and they will settle at their isoelectric point, you can then turn the gel by 90 degrees and separate in that other direction by eg mass, to get a much more accurate determination of the protein

Cytosol vs Cytoplasm
A good explanation of the meanings of these two words :

Actin / Myosin in Muscles
I also have a quick cartoon of actin / myosin movement - if you would like a copy then I can give you a copy when I am tutoring you, or else drop me an email and I can see if I can provide you with a copy.

Resting Potential /Action Potential in a neuron - Na / K pumps too !

Topic 4 Detecting and Amplifying a Stimulus

Photosystems in Plants
On the thylakoid membrane there are light receptors - here is an animation. Its in a bit more detail than you need so just watch the overall idea of what the electrons and H+ (hydrogen ions) do :
https://highered.mheducation.com/sites/9834092339/student_view0/chapter39/photosynthetic_electron_transport_and_atp_synthesis.html


Photosystems - Chlorophyll and Photosynthesis
Interesting and useful reference. Did you know that the grana are actually structured similarly to the retina - strangely very similar - but evolved independently - I guess both have the same purpose of capturing maximum light and maybe based on similar proteins - so have evolved similarly:
http://photobiology.info/Brennan.htm


Rhodopsin
http://www.chm.bris.ac.uk/webprojects2003/rogers/998/Rhoeye.htm

Would you believe that birds have better vision than humans ? they also have cone cells that detect uv light - read more if you are interested here (not in the course - but then you never know what might come up !) - http://www.nwf.org/news-and-magazines/national-wildlife/birds/archives/2012/bird-vision.aspx

Retina article - Scientific American Magazine
There is nice information about the retina and how it works here - its more information than we need at Adv H
http://www.americanscientist.org/libraries/documents/20058313632_306.pdf

If you'd like to find out a lot more about the retina and the human eye - there are some good animations here - but this is a step beyond Adv Higher-

Coral bleaching and photosynthesis
OK this 3 minute video is really more the content from Higher Biology - but it does talk about photosynthesis and thylakoid membranes - and you get to see a tropical island in this short video ! nice to watch !

Neurotransmitter and some medical drugs that affect it
http://thebrain.mcgill.ca/flash/i/i_01/i_01_m/i_01_m_ana/i_01_m_ana.html

Topic 5 - Communication Within Multicellular Organisms

A hydrophobic signalling molecule - lipid soluble so a steroid hormone - can cross the plasma membrane (here is an example aldosterone ..you don't need to memorise the name of this particular hormone - just look at its action in this animation - but its to do with regulating salt levels in the blood by getting the kidneys to re-absorb salts and hence it regulates blood pressure)
http://highered.mheducation.com/sites/0072507470/student_view0/chapter17/animation__intracellular_receptor_model.html

A steroid hormone by contrast
http://highered.mheducation.com/sites/0072943696/student_view0/chapter10/animation__mechanism_of_steroid_hormone_action__quiz_1_.html

G Protein
http://highered.mheducation.com/sites/0072507470/student_view0/chapter17/animation__membrane-bound_receptors_that_activate_g_proteins.html

G Protein GTP GDP and cAMP ? do we need this ?
http://highered.mheducation.com/sites/0072507470/student_view0/chapter17/animation__second_messenger__camp.htmlhttp://highered.mheducation.com/sites/0072507470/student_view0/chapter17/animation__second_messenger__camp.html

G Protein - receptor etc. Epinephrine (you may know this as Adrenaline) .. and how it induces cells to release glucose ....   I just hope you don't need to memorise all this !! But watch this anyway so you can begin to get the ideas of the principles of passing messages along and the use of phosphorylation etc. to change structures of proteins :
good video from a school project :
http://wn.com/ap_biology_stop_motion_g_protein_receptor_system_for_epinephrine
and here is another fab video of the same thing- another school project with clever and simple animation : http://wn.com/ap_biology_stop_motion_g_protein_receptor_system_for_epinephrine
here is a bit more ... http://www.ncbi.nlm.nih.gov/books/NBK22429/

How Epinephrine (known also as Adrenaline !) makes a cell secrete Glucose during the fight or flight response (second part of this video is probably too much detail for Adv Higher so dont panic !) :
https://www.youtube.com/watch?v=Nt2r5R0ZO5U

GPCR - G Protein Couple receptor
http://www.nature.com/scitable/topicpage/gpcr-14047471

Receptor Tyrosine Kinases
https://www.youtube.com/watch?v=ObrsQl-vPA4

Signal Transduction
I like this video from the Penguin prof ! Only thing to watch for is she talks about lipophillic and lipophobic signal molecules where they either like or hate crossing the fatty or lipid membrane. However in the Advanced Higher course we tend to talk of these the opposite way and talk about hydrophobic or hydrophillic depending on whether they like or hate water.  its worth watching though as the rest is pretty much part of the course.

Cyclins and Kinases and p53 - 
I quite like this website- it is presented as questions ...
click on the red figure text to see the graphics.
Just pick out what is helpful - its not all in Adv Higher and the graph of cyclin does not really coincide with the one in the Adv H book, but there are some helpful bits - so just take what is useful.

UNIT 2 - Organisms and Evolution

1 Field Techniques for biologists

a) Health and Safety

b) Sampling of Wild Organisms

c) Identification and Taxonomy
Three Domains etc

Protected Species in Scotland : 
http://www.snh.gov.uk/protecting-scotlands-nature/protected-species/

Some model organisms :
http://eol.org/collections/98 - important ones we study are E.coli, Arabidopsis thaliana, C. elegans, Drosophila melanogaster (fruit fly), mice, rats, and zebrafish


but there is also Zebra Fish !
How Zebrafish model organisms are used to study cancer biology -

Fruit fly model organism :
http://modencode.sciencemag.org/drosophila/introduction

The 3Rs of using animals in research https://speakingofresearch.com/facts/animal-welfare-the-3rs/

Domain Kingdom Phylum Class Order Family Genus Species

http://www.mensaforkids.org/teach/lesson-plans/classifying-animals/

For humans we would be classed as follows:

Domain - this is right at the top - there are 3Domains and Humans would be Eukaryote
Kingdom - Animals
Phylum - Chordates (backbone)
Mammals (fur / produce milk)
Primates (collar bone and grasping fingers)
Hominids (flat faces / 3D vision) 
Homo (upright posture / large brains !)
Sapiens (large forehead / thin skull) 

Animal Kingdom - Plant Kingdom etc - Classification
http://www.explorebiology.com/documents/ReviewAP/07ClassificationList.pdf

Here is how humans are classified : 
http://biology-igcse.weebly.com/classification-of-living-organisms.html

bit of confusion about where algae (which can photosynthesise) are classified :
this is good from Wikipedia : https://en.wikipedia.org/wiki/Algae

The largest phylum is arthropods ... followed by .... molluscs ! - lots of mollusc info here: http://www.molluscabase.org/

Arthropods
http://evolution.berkeley.edu/evolibrary/article/arthropods_toc_01

Platyhelminths : http://www.coolgalapagos.com/animals/platyhelminthes_flatworms.php
Chordata - Vertebrates - including sea squirts - http://www.coolgalapagos.com/animals/vertebrates_chordata.php

d) Monitoring Populations
using indicator species to classify habitat using British Vegetation Survey

also here is a field guide to woodland types - might be useful if you are doing a project on this but is a bit too detailed really for most of us - http://jncc.defra.gov.uk/page-4261

e) Measuring and Recording Animal Behaviour

2 Evolution

3 Variation and Sexual reproduction

e) Measuring and Recording Animal Behaviour

3.2 Evolution

a) Drift and Selection


Fitness - and Sexual Selection

b) Rate of Evolution

c) Co-evolution and the Red Queen Hypothesis

Red Queen Theory 
http://evolutionbiology.com/evolutionary-principles/red-queen-principle/

3.3 Variation and Sexual Reproduction

a) Costs and Benefits of Sexual and Asexual Reproduction

The two-fold cost of Sexual Reproduction (vs asexual)
http://evolutionbiology.com/evolutionary-principles/the-paradox-of-sexual-reproduction/

Algae and Fungi
have haploid nuclei - who'd have thought it ! so that is why they can reproduce via haploid spores - http://www.ehow.com/list_7674705_similarities-between-fungi-algae.html
To find out which species are classed as Algae and Plants or Fungus and Lichen, you can look at photographs of them in the ARKive website - http://www.arkive.org/
Fungi information - some easy facts - http://easyscienceforkids.com/all-about-fungi/

Spores are produced during sexual and asexual reproduction in algae and fungi. They are most often haploid, but can be diploid.

A zoospore is a motile asexual spore that uses a flagellum for locomotion., allowing them to move to a more favourable environment. Created by some algae, bacteria and fungi to propagate themselves.

Asexual reproduction in fungi - you can see a picture of budding in fungi here - ie one yeast splitting into two new identical yeasts http://classes.midlandstech.edu/carterp/Courses/bio225/chap12/lecture1.htm

b) Meiosis forms Variable Gametes

Details of Meiosis stages
This is probably more info than you need on this website here, but might help if you are looking for answers about eg what happens at Prophase 1
http://www.phschool.com/science/biology_place/biocoach/meiosis/proi.html


c) Sex Determination

Parthenogenesis
Fitness - and Sexual Selection

Sex Linked Inheritance
http://www.nhs.uk/Conditions/Haemophilia/Pages/Causes.aspx

Colour Blind Test - Colour blindness or a problem with colour vision is a sex linked inherited trait - to try the test to see if you vision is affected you can have a look here, although hopefully your optician will have already checked this with you. It is more commonly found in boys due to the XY chromosome vs XX in girls: http://unlimitedmemory.tripod.com/sitebuildercontent/sitebuilderfiles/ishihara38.pdf

Edmund Beecher Williams and Nettie Maria Stevens - read about these scientists who independently worked out that gender is determined by chromosomes 
https://www.dnalc.org/view/16250-Animation-9-Specialized-chromosomes-determine-gender-.html

Wolbachia bacteria being used to infect Aedes aegypti mosquito (which is responsible for spreading Dengue fever and Zika) so that it only produces male offspring and will then be wiped out hopefully http://evolution.berkeley.edu/evolibrary/article/evo_27

Very interesting about Kakapos - cute green type parrot bird - and how scientists discovered why they can have more girl or boy babies ! http://evolution.berkeley.edu/evolibrary/news/060401_kakapo

Specific cellular defence in mammals involves immune surveillance by white blood cells, clonal selection of T lymphocytes, T lymphocytes targeting immune response and destroying infected cells by inducing apoptosis, phagocytes presenting antigens to lymphocytes, the clonal selection of B lymphocytes, production of specific antibody by B lymphocyte clones, long term survival of some members of T and B lymphocyte clones to act as immunological memory cells.

Clonal Selection
