Isn't oxygen debt the lack of oxygen in the tissues?The oxygen required to metabolize/use up the lactic acid produced (or respire it completely)

We know that there is lack of oxygen. If there wasn't any lack of oxygen, then anaerobic respiration wouldn't have started in the first place.Isn't oxygen debt the lack of oxygen in the tissues?
Okay, let's say you're sick, so you need to take an antibiotic. We know that antibiotics are useless if bacteria are resistant to it.
During the process of genetic engineering, we made plasmids that have an antibiotic-resistant allele.
If you take insulin that's made from these plasmids, then the insulin you're taking has the antibiotic-resistant allele.
When the antibiotic-resistant allele is expressed, it will give a protein that counteracts the antibiotic you're taking.
So the antibiotic you're taking is useless.
First of all, my friend, I've never seen crop plant questions come in Section B. Second of all, don't memorize, understand. Understanding is the best way to grasp the context of what's happening. this way, you can even answer the Section B questions in your own words and be absolutely epic at it...try understanding the topic, if u don't get it, ask again, I'll explain it to you inshAllahGuys, I don't understand anything about polyploidy >.<
Do I have to memorize the wheat example, and how species bred and formed a hybrid that are sterile and then by chance, polyploidy took place forming a fertile tetraploid that could mate , etc etc..do I have to memorize the number of chromosomes and connect this with autopolyploidy and allopolyploidy ?
How would I ever answer that if it came in section B ;_;

Chill Dude..chill!Hehe, thank you for the kind offer.
I am a bit frightened as they changed the syllabus for 2013, they will include things from application. I am not even well prepared for the core topics, so scared to be stuck explaining these things.
I am very scared they might get from the AS, I read briefly the biological molecules, the enzymes and immunity. Do I need to read anything else? I'm kind of in a panic mode but trying to calm myself down because I wasted too much time panicking. Caused to myself synaptic fatigue xD
