This question wants to effectively test your knowledge of the names of the negative powers of 10, so first of all, before calculating, let me explain what each of the symbols in the units given in the question means:

Force = 8.0 pN = 8.0 × $10^{-12}$ N

displacement = 8.0 nm = 8.0 × $10^{-9}$ N

Now let us calculate the work.

work = Force × Displacement

work = 8.0 × $10^{-12}$ × 8.0 × $10^{-9}$ = 64 × $10^{-21}$

= 6.4 × $10^{20}$ Joules (in standard form)

Kira is a hemophiliac. This means that she does not produce clotting factors. What aspect of the clotting process should she be

meriva

A hemopheliac is someone with a bleeding disorder resulting from any missing clotting factors in their blood. Vasoconstriction isn't generally the problem in hemophiliacs, nor is it the destruction of pathogens. If fibrin threads are not present to help form the platelet plug, then excessive bleeding occurs. Fibrin is one clotting factor that a hemophiliac may be missing which is then causing the disorder.
