Guys
How exactly does obesity lead to CVD?...

ohh...thank u so muchFrom the table, this is the lowest magnification...lowest magnification means that the size of each cell will be the smallest and so the maximum number can be seen
The smaller the size of an object, the more of them can fit in an area of space
Just look at the y-axis... it is time taken for reaction, not the rate of reaction
To know refractory period, you must know about hyper polarization. Once the cell fires action potential when threshold value is reached then, depolarization occurs and when the cell re-polarizes, it goes beyond the normal resting potential value i.e. hyper polarization. To bring the cell back to resting potential, the cell needs some time and this period is known as refractory period. During this period, the sodium potassium pump plays an important role by letting 3 sodium go out of the cell and 2 sodium into the cell for each time thus, bringing the cell back to resting potential. I hope I made my point.Re: Biology Doubt: Nervous System!
Assalamoalaikum!
Can someone please explain, what's refractory period? I am confused about it! =/
Thanks a lot!! You did.To know refractory period, you must know about hyper polarization.

XDThanks a lot!! You did.
But guess what? That's a 6 year old post. I'll almost done with uni
can someone help plzzz why for 18 ans is B??
also 7 why ans is C??

can someone help why answer is C?
It is the point where the ratio of initial length to final length is 1, which is 0.45 moldm-3 sucrose concentration (from graph).
at one , the length after immersion, and before immersion is the saem, this means that no water was lost/ taken in, which means that the water potential of the solution= water potential of the cells,so when it is 1 the water potential is equal to sucrose plz explain in further detail
since adult haemoglobin is produced, oxygen is transported normally I guess, maybe because person is heterozygous, so he is only a carrierhelp question b(ii)plz

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.
