What is a standard error?
It measures how close to the population mean is you sample mean.
What is the principle of regression to the mean?
If your results are very far from the mean, there is a chance that it is not valid. Retesting it will probably give a more logical result. It is therefore important to retest when you are not sure.

It is a route for metastatic spread within the body cavities.
What is the difference between grading and staging for a neoplasia?
- Grading concerns the degree of differentiation of the neoplastic cells. (low grade --> well differentiated--> good sign!)
- staging concerns the size and the extent of spread

- targeted screening (a specific population at risk)
- case finding (opportunity of a health contact)
What is length-time bias during screening?
It just means that you have more chance to detect people having a slow progression disease than those with a fast progression(because they have a shorter pre-clinical phase and they will be "normally" diagnosed)
What is lead-time bias?
The lead time is the moment between detection by screening and detection when clinical signs appear. If you look at the survival time, people that you detect first (even if they get the cancer at the same time) will appear to live longer

What is FISH?
- It is looking at the absence or the presence of a specific sequence with a radioactively labeled probe
Explain the selectivity of the K+ channel.
The pore of the channel is so small that the particules have to get rid of the water bound molecules before going trough, but this "cost" energy. The only way to "pay" it back is to make links with the oxygen molecule inside the pore. But the Na+ molecule is to small to make enough link (it doesn't "touch" enough).
What is a neoplasm?
