I have to make a drawing of this for my AP bio class and i don’t know how they do it…

Throughtout my pregnancy, my BP remained low. but it recently it became slightly higher liker 140/90. and i m also having swelling in my feets and legs.

i do not understand how to do this problem for my chemistry homework… this is the problem "Calculate the average mass of potassium if the abundance and atomic masses making up its naturally occuring samples are:
Potassium-39 93.12% 38.964
Potassium-41 6.88% 40.962"

thanks

Dehydration means that your body does not have enough fluid to meet your metabolic needs. Learn how to identify dehydration and treat dehydration in this health video.

Most supplements I’ve found contain only 99 mg per dose.That’s nonsense.The RDA for average people is 3000 mg.I’m an athlete and I need way more than that.I eat alot of fruit and supplement whey protein as well so that’s where most of my potassium comes from.I don’t drink milk because I hate it.I’m well aware what foods(including meats) have potassium in them but I’m looking for potent supps.Don’t say Gatorade either because there is only about 50 mg per serving..
I said no gatorade brain surgeon and I don’t drink milk.I powerlift 3 times per week and study martial arts.My best dead lift is 540 lbs,squat 505,lbs and bench 340 lbs.Don’t tell me I’m not working out that hard!

I work full time and go to graduate school full time and find myself eating on the go. I don’t have a lot of time to exercise, but I do make time to go for walks to relax and get outside once in a while. As a result, I feel myself not having the same figure I did even a year ago. I’m not overweight, I just don’t always feel so good eating bad things all the time, and I feel my clothes tightening a bit. Any tips on how to eat on the go but still eating healthy? Any tips on how to do simple things to exercise too? Like taking the stairs instead of the elevator, etc.

I mean super low potassium levels, less than 2.0 instead the average 3.5.Does anybody know exactly how this damages your body ?
