Which protein would elute first from a gel filtration column?
protein c, a homodimer with protomer =11300mr=11300
protein a, with =27000mr=27000
protein b, with =58400mr=58400
protein d, with =15600mr=15600

Protein B with 58400

Explanation:

is an abreviation of relative molecular mass and is a measure of weight in macromolecules such as proteins,.

If you compare and order the macromolecules you obtain:

Remember that the largest protein will emerge first of the gel filtration column, and so on, until the smalest protein have been emerged. The above due to the smallest protein moves a longer distance than the largest protein.

In view of the above the largest protein is protein B with 58400

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
