a. red blood cells and oxygen transport (think of hemoglobin protein that gives the red color and is a transporting protein)
b.white blood cells and fighting disease.
c.platelets are cell fragments that are used for blood clotting
d. antibodies as far as I know deal also with fighting disease
e. hormones are chemical signals
f. clot forming proteins should be platelets.

I hope this helps some, but the question was a little bit confusing to me.

There are some weird things here, because a platelet is a protein the blood that helps form clots.

But here goes:

A 3 5 6
B 5 4
C 2
D 5 4
E 1
F 2

2 says preventing blood? What is this, if you retype it more clearly, I’ll double check the answers

Hope this helps!

Thanks for fixing, I fixed the answers!

Good luck!
