Hello!
Clubbed finger tips usually means the person has lung or heart disease. It only makes sense if he smokes a lot of cigarettes (2 packs is a lot). The more he smokes everyday, the higher chance he could get the disease. Just to be sure, you might want to do tests for lung and heart disease. The coughing up blood might be a the result of smoking. It really depends on his state of shape and all of that stuff.
Have a lovely day! ~Pooch ♥
I believe it's the last two. "makes the lungs able to fill more completely" and "helps the blood vessels dilate more easily" hope this helps, have an amazing day :)
Restrain i know this for sure

Explicación:
La molaridad se define como la relación del mol de una solución por litro de su solución.
Molaridad = Mole de soluto / solución (en litros)
La solución aquí es agua = 250 ml = 0.25L
El soluto es cloruro de potasio (KCl)
Para obtener el mol del soluto, usaremos la fórmula;
Mole del soluto = Masa de KCl / Masa molar de KCl
Masa dada de KCl = 35 g
Para la masa molar de KCl donde K = 39 g / mol y Cl = 35 g / mol
Masa molar de KCl = 39 + 35 = 74 g / mol
Mole del soluto = 35/74 = 0.473 mol
Molaridad = 0.473mol /
0.25L
Molaridad en la solución = 1.892mol / L
It's A because it's a good amount that can fit a regular cup.
