My Latest Revised

May get my latest revised 'pet project'..from any book store in town. You may use it to get the overview of all chapters in the syllabus..Short and precise..Happy revising .

Thalassemia

Yes...its stated in the syllabus~ a minor section in Chapter: Inheritance

Thalassemia............

I have reminded my students to know ALL the diseases stated in Bio Text Book by observing :

What? Who? Why? When? How?

..and they did not expect of all the diseases, this is the one asked in SPM 2011.

THALASSEMIA:

- a hereditary disease.

Explain the cause of this disease:

* caused by a autosomal recessive gene

* which leads to the synthesis of abnormal haemoglobin in red blood cells [ 2marks]

how it affects a person's health?

* they grow slowly, often develop jaundice.

*the red blood cells are smaller.

* without treatment, spleen,liver, and heart soon become enlarged.

* bones become thin and brittle.

* Heart failure and infection leading to death. [ Any 2 marks]

Variation Graph

Any question involving Variation, if data is given as Table below.., make sure you divide it into range..

and dont forget to prepare 'tally' to find its frequency.

Next, draw a HISTOGRAM for continuous variation..

and BAR CHART for discontinuous variation..
Draw Graph:

1. Uniform scales for both axis

2. Label the axis...dont forget the UNIT (....)

3. Transfer all the points CORRECTLY

Paper3 ~Last Review

All the best :)

Exam Wish

ALL THE BEST....DO YOUR BEST !

Sample Q&A Paper 3 Qs2

Its Transpiration....
You may produce a Diagram of a set up of apparatus...but...make sure it has at least 5 labels to entitle point (not marks) for your procedure !

It is POTOMETER..

// means either or...

The underlined ones are A MUST..without those, your marks will be reduced by 1.

Observe how the procedures are written above..

Identify which are K1, K2, K3, K4 and K5

Make sure your TABLE must have MV, RV and units.

NO CONCLUSION is required.

Bio Intensive Revision

Trying to be cool...but its becoming hot...especially when SPM is knocking at your door :))Doing intensive revision with 4 classes gathered in the same venue...it must be challenging !!
We don't have an auditorium at our school...teachers are fighting for a place...

To conduct a massive lecture, I surely need a spacious place....

The revision is by chapters..
So far the girls response well....Ask them :)



I have completed doing ALL CHAPTERS last two weeks...The rest is left for polishing the chapters :)

It must be done BASED ON EXPERIMENT GIVEN.

How to define operationally

How to go about answering question : Define operationally.

1. Do respond to the question..

2. Observe the proper way to write it by looking at the following examples.

Sample Answer Paper 3 Qs2

Hello students..

Please go through the corrections that I have made~ with the latest format, there are a few changes to be observed !

Ady : Please look at the ways to write procedure.

Sample Question

Answer:

· DNA fingerprinting is a technique used to identify parents of a child based on DNA banding similarity

· Generally, the DNA profile of a child is the combination of the mother and father.

· A child inherit half of the chromosomes number from father and half from mother.

· DNA fingerprinting gives more details and information regarding the identity of a person while thumbprints give general information as it is based on a few different types.

· A blood sample, seminal fluid or any tissue can be analysed and its result is compared with thatof an individual who is a suspect.

* In conclusion, man P is the father of the child as the similarity of his DNA is higher

Sample Qs

1. (a) Explain the principle involved in genetic engineering [2 marks]

· Genetic engineering is a technique of manipulating the genes in an organism by removing a gene from one organism and transferring it to another organism

(b) Discuss the importance of genetic engineering in the medical and agricultural field. [4 marks]

The importance of genetic engineering in the medical field.

· Production of insulin from bacteria.

· Gene from the pancreas that can produce insulin is removed and inserted into the DNA molecule of bacteria.

· The bacteria that can produce insulin grows very fast in a suitable nutrient medium.

· Insulin can be produced in large quantities in a short time.

Genetic engineering in agriculture.

· Produce food or plants which are genetically modified to produce high quality yield.

· Produce plants with high quality yield as they are resistant to viral attacks, pesticides or predators.

Quadrat Sampling

Quadrat Sampling Technique.

4 Gastisia girls were at the school field to investigate the distribution of plants using the quadrat sampling technique ...
It was noon.....and its a bright sunny day.
They used a prepared metal frame quadrat..


They were counting the coverage of the species..





And later calculating it...

Sample Question

I like this question :)TQ

Sample Question

Its haemophilia......
