Answer:
Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ ions cannot cross a lipid bilayer by free diffusion.

Answer:
total amount spent on student ticket = 186($2.5)=$465.00,
Total amount spent on adult tickets = 135($3.5)=$472.50
Explanation:
cost total = student ticket price (x) + adult ticket price (321 - x)
$937.50 = (2.5)(x) + (3.5)(321 - x)
$937.50 = 2.5x + 1123.5 - 3.5x
x = 186, therefore 186 student tickets sold,
(321-x) = 321-186 = 135, therefore 135 adult tickets were sold.
total amount spent on student ticket = 186($2.5)=$465.00,
Total amount spent on adult tickets = 135($3.5)=$472.50
So the total amount spent on tickets was
$472.50 + $465.00 = $937.50
The answer would be respiratory because that system is used to breath oxygen and exhale carbon
