Wasnt It Bio Technology ? Fermentation is in making Alcohol

I actually wrote Bio Technology but most of my friends told that it was fermentation

how
how can wild lupins be asexually reproduced ....they reproduce sexually......i wrote abt genetic engineering in tht answer...

exactly.... genes were transfered from another plant which had larger flower spikes and had a variety of colours.
But the question was actually 5 marks,didnot know how many keypoints it had

Fermentation is the most appropriate term used for the large-scale antibiotic manufacture.

which two organs would be exposed to infection???? what were the correct answers

Liver and spleen/pancreas/intestines/colon.

I wrote liver and lungs >.<
At first, the question didn't state whether the bullet had penetrated above or below the diaphragm. Any tiny bit chances of LUNGS being right?

 

[Asif1223]

i wrote lungs and liver.. But still confused

 

[ritx]

The stomach has less chances of catching any infection because it secretes gastric juice that contains concentrated HCl destroying most of the micro-organisms since they can't BREED. It's a cavity where from infection can't spread elsewhere.

It's not BIOTECHNOLOGY or BIOENGINEERING guys. They are broad spectrum terms.
Here I paste some text from WIKIPEDIA directly:

Industrial production techniques
[edit]

Antibiotics are produced industrially by a process of fermentation, where the source microorganism is grown in large containers (100,000–150,000 liters or more) containing a liquid growth medium.

liver and lungs is absolutely correct

liver and lungs is correct...very small chances of intestines being correct

But the question was actually 5 marks,didnot know how many keypoints it had

so we both wrote genetic engineering....yup it is the right answer and even if it were 5 marks at least 2 marks can be awarded.....

The problem is that the latter parts of the question mentioned quite clearly that the bullet had penetrated UNDER the diaphragm. Lungs are above it. What did u write in your ans?

How about selective breeding? I wrote about that.

i guess it could be correct....partial credit maybe...

i knw wat the question mentioned......but viruses are veryyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy small....so they can easily get through and cause indection
I wrote liver and lungs.

 

[ritx]

why partial credit, it's vast.

INFECTIONS ARE CAUSED BY BACTERIA!

remember that in selective breeding, only similiar plants or plants of the same species can breed...in the same way take an example you cannot cross a lion with a cheetah....right? but genes can be transferred irrespective of the species......for example there is a type of jelly fish which has a gene which causes the jelly fish to give a blue colour when it is in stress.....that gene was inserted into a sheep which also glowed blue......
since the question said varieties of colours, you cannot get a very large variety through selective breeding, because only limited alleles/genes are involved....however through genetic engineering the case is totally opposite.

BROOO,
INFECTIONS ARE CAUSED BY BACTERIA!

oh for cyring out loud fine bacteria....although have you never heard of the word viral infection...Jeez brah......
anyways even bacteria are pretty pretty small.,.....

That's just a layman term 'viral infection'.. Basically infections come from bateria. why are we at each other's throats over something not even relevant to Bio P2? lol
