Biology
Areb't they the same thing since both solutions are 300mOsM?

Biology
How is it a solution of 300mOsM NaCl is both isotonic and isosmotic to a red blood cell with an osmolarity of 300mOsM? Yet a solution of 300mOsM urea is only isosmotic to that red blood cell?

math
Given that AC and AE are common external tangents of circle G and circle D, FE = 15, GF = 3, and AG = 5, which is the length of AC?

physics
A 1.6-kg block is dropped from 66 cm above a spring in equilibrium. The force constant for the spring is 142 N/m. Calculate the maximum compression in the spring.

physics
A student in a lab exerts a 14 N force to pull a block a distance of 63 cm. If a total of 8 J of work is done, the angle between the force and the displacement is none of the above 89° 25° 61° 65°
