Exams are coming! Arghh!

2009-09-02T00:12:00.000-07:00

Hello boys and girls,
as the BIO EOYs are coming, gentle reminder that these topics are not tested:
1) digestion
2) Reproductive system (Circulatory system is tested! haha. sorry for the error) :p

Pls see me for consultations if you are unsure by 1) emailing me 2) SMSing me 3) Ringing my phone 4) Any other methods and means you can think of. :p

Why is it always about pea plants and fruit flies?!

2009-08-03T20:05:00.000-07:00

Hello students,
here is the Genetics slides as promised. Though we haven't finish going through everything here, but it's worthwhile to read through the slides first! :)
I will be back next Thursday and we will finish up multiple alleles, incomplete dominance, co-dominance, sex genes.
Pls pls pls try the qns on ur own and do the worksheets.
I can still be reached by sms, phone, email(if there is internet access)
Be good! Pay attention at the practice pract.

NEW stock in store! All you need to know about DNA

2009-07-14T17:17:00.000-07:00

Hello,
You can now access the slides on DNA! Remember, this is just level 2 of what you would learn of molecular biology. There's more (if you continue to take Biology of cos) :)
Enjoy!
Let's move to Genetics now! :)

Human repro...

Need help in blogging!!

2009-03-11T18:24:00.000-07:00

Hello,
if you have noticed, the template is really plain and boring and my chatbox cannot seem to work now. I seriously need help!
Any willing volunteers?

A very unfortunate case of mild amnesia with 08V11

2009-03-04T21:16:00.000-08:00

So... to continue where i left off on Lymphatic systems,
If blood keeps leaving the blood capillaries and become tissue fluid, then the cells and tissues will swell from the water in the tissue fluid that will move into the cells by osmosis. This is NO good.
So, there exists 2 systems in place to absorb fluids back into the system and at the same time to remove waste materials.
1) Venule end of capillaries
2) lymphatic capillaries

Lymphatic capillaries are located near to the blood capillaries. Blood flow is slow as there is no heart at the lymphatic capillaries to provide pumping force. So, lymph inside the lymphatic capillaries move by the action of muscles. (lymphatics are also located near muscles).
Lymph in lymphatics move to the heart eventually (along the way removing the metabolic wastes).
Thus, these 2 systems prevent conditions like oedema.
Oedema can occur in conditions when:
1)Inflammation increases osmotic pressure outside the blood capillaries
2)Increased hydrostatic pressure inside the blood capillaries (for example in heart failure)
3)The permeability of the capillary walls increases in an inflammation which causes more fluid to leave the blood capillary.

That's all!
All the best for the RT!

Circulating... Circulation...So Bloody...!

2009-02-25T01:35:00.000-08:00

Hello! HBL.. what is that? Home. Based. Learning!
So in essence, it means that
1) You do this at HOME!
2) You LEARN!

Ok, no DIM DIM, no Bright Bright, no Dark Dark for MISS CHUA's Biology.
So it's just the good old boring misschuabiology.blogspot.com! :)

So what?

1) You may read through my Circulation slides. (Which i will still run through the contents next week when i see you all in person!)
2) See the heart dissection slides. Warning! Not for the faint hearted! :P
3) Attempt the question below. Answer in your Biology notebook. We will go thru in class next week! :)

Question:

If you could re-design the single circulatory system of a fish by re-locating the various blood vessels, would you place the pulmonary arteries and veins before the heart or after it? (In other words, would the blood enter the gills before it enters the heart, or vice versa?)

Explain your choice with reference to how the rate of exchange (between blood and the body’s tissues) and the rate of transport (of blood to various parts of the body) would be affected.
[7 marks]

Ok. Yay! Done! See you all for Cross country tmr!
I will be running! Support me hor! Will try not to faint halfway. keke

My Biology lesson next week!

2009-02-18T23:20:00.000-08:00

Hi 11 and 12,
I won't be around in college on monday and tuesday next week. So what to do?

Mon and Tues lesson: Bring your Bio textbook. Read the handout given (will be passed to Bio reps) and textbook. Try to understand the graph and the changes for blood pressure changes and velocity as blood travels along the vessels.

Thursday lesson: HBL. READ MY BLOG FOR WHAT TO DO! :)

New year 2009!

2009-01-15T20:52:00.000-08:00

Welcome 08V11 and 08V12!!! 2009, new year, new initiatives.
1) This year on, there will not be any notes given out after each topic. References used for preparations for exams will be your textbooks and handwritten notes taken lessons. Soooo... this means that you have to PAY attention during my lessons ok? :)
2) 2009 syllabus outline and CA1 assessment components will be given during lesson 1 next week.
3) Every Biology student will also have to sign and acknowledge the "laboratory safety" form. (To be given out next week too!)

Next week: Revision on IP1's work. To do practice paper (MCQ+STQ+1 essay)) during lesson. Pls revise! :)

First topic: RESPIRATION.
