Can anyone post here notes for Diseases caused by Smoking? Please....
Can some one please clear my doubts?
Why does the mosquito have to secrete an anticoagulant the second time into an uninfected person but not the first?
Why there is an increase in the resistance in the blood vessels surrounding the lungs of an emphysema patient?
What is the difference between open and closed circulation?
So that the blood won't clot immediately which kills the host instantly. Plasmodium needs a host to survive.Can some one please clear my doubts?

So it's not like what panda said above? that it does secret both the times , but it only matters the second?there is a great resistance when the alveoli expand, but what does that have to do with the blood vessels?.. thanks a lot for the helpSo that the blood won't clot immediately which kills the host instantly. Plasmodium needs a host to survive.
In emphysema patients, most of the elastic fibres are digested by white blood cells, so there is much greater resistance when the alveoli are trying to expand.
A closed circulation system is one in which all the blood is contained in blood vessels (arteries, veins, and capillaries). An open circulation system is where there are no blood vessels. The blood-like liquid is just pumped by the heart all around the body.
The proteins to be processed or exported to the cells , their growing chain of amino acids made at the ribsomes on the RER is moved to the cristae of the RER . The cristae then breaks off , forming small vesicles that are transported to the Golgi apparatus , where the protein is modified , by adding a carbohydrate chain for example , then the vesicle containing the modified protein breaks away from the Golgi body and is transported to the cell membrane for secretion by exocytosis. Hope this helped. Btw I don't think proteins are packaged into lysosomes , because the hydrolytic enzymes probably digest it , so I think it's wrong to say that , because they're transported in secretory vesiclesHow golgi apparatus packages protiens into lysosomes?? :/
It secretes both times, and both matter (not only the second).So it's not like what panda said above? that it does secret both the times , but it only matters the second?there is a great resistance when the alveoli expand, but what does that have to do with the blood vessels?.. thanks a lot for the help
Wa3alaikumussalam wa Ra7matullahi wa Barakatuhu!Aoa wr wb,
Can someone please look at qn 6 d i) of this paper and elaborate on conjugation and transduction and all that please?

Thanx a lot
knowitall10But Soldier313 Either way, both vertical and horizontal transmission are dangerous because if the bacteria are released into the wild, they can bring rise to furthur incurable diseases and add to the problem of antibiotic resistance.
heres the experiment, the pictures are from the mary jones book.hey can any1 explain the meselsohn dna experiment. I cant understand it
As far as I know, if you mention 5 points out of 10, you'll get the full mark. But you have to make sure that all the points you mention are in a clear and logical order.I have a pretty silly question if we encounter a question for say, 5 marks, and the marking scheme gives 10 seperate points which are relevant to the question, does that mean we need to tell them all 10 separate points?
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
