Done with Paper 3 Bio

[Zeus]

What'd you guys write for the natural selection conditions ? And the blue light question was- Lack of pigmentation causes the seedlings to have no change to blue light stimuli.

What'd you guys write for the natural selection conditions ? And the blue light question was- Lack of pigmentation causes the seedlings to have no change to blue light stimuli.

I guess there wasn't a question about natural selection.
It was about selective breeding and genetic engineering (modification).
And answers were like you had to compare (for that african plant..) the natural selection takes in features of both crossed breeds where as inserting the particular gene only changes a single feature, etc.

Heartv

I'll tell you the stuff that came: Biology Paper 3 - Variant 2:
-Importance of vili and its function in Kidney Tubule and Small Intestine
-Substances that are absorbed by them (glucose, water, etc.)
-Heart
-Lung
-Binomial classification system, mammals.
-Selective breeding

What exactly came = heart and lungs in diagram, was there the eye, what about the nitrogen cycle was it in detail and what questions came in genetic engineering ?





-Genetic Engineering
-Nitrogen cycle
-Auxin, role of a pigment in detection of blue light.

It was an easy paper..

lung and heart was it a diagram or essay, what question came in genetic engineering th insulin or biological wahing powders and what type of

 

[beewhiz997]

omg i just realised i wrote cilia for the first q instead of villi........

Guys How Do Bacteria make insulin in ferminator i know we supply nutrients ,...etc but what does the bacteria do ?

Heart was a diagram, naming the different blood vessels (pulmonary arteries, etc.)
Then there was a question about the valves, what is the difference between them and where they could be found in the body other than heart.

Guys How Do Bacteria make insulin in ferminator i know we supply nutrients ,...etc but what does the bacteria do ?

Genetic engineering was used to put the human insulin genes inside bacteria so that they produce insulin which can be taken, purified, and used to cure diabetes. How: all bacteria have plasmids, circular pieces of DNA, inside them. These are extracted and cut using an enzyme. At the same time, a section of human DNA is cut using an enzyme as well. The plastids then take up this human DNA to complete them, and now contain the insulin gene. This causes them to produce insulin. This bacterium is then cloned.

 

[natsume hyuga]

so topics that came in the previous year was also repeated then?

 

[beewhiz997]

Oh gosh, I wrote cilia.

ME TOO something is wrong with me....

What about the small intestine question ? And the heart included the vena cava aorta ?

 

[examkiller]

Was there a question about the eye ? And excretion ?

 

[mrnt3250]

What about the small intestine question ? And the heart included the vena cava aorta ?

Small intestine was in form of a question with two diagrams, one for kidney tubule other for small intestine.
---
Memorize the structure of heart for such questions.
---
No questions about eye and excretion.

What? I've never heard of valves other than in the heart.. Where are valves found other than heart?

Ok thnks but what small intestine was it like state a feature and its function ?

 

[Hamzeh S]

in veins

 

[Ali_Hasan]

in veins

Oh ok, if that's the case then I already know. I just thought it's completely out of the circulatory system.

 

[examkiller]

Was there about the circulation like coronary circulation or liver ?

did u do paper 31 or 32
