Answer:
Angle between the forces 
degrees
Explanation:
The resultant force value 
times of Force F
Where R is the resultant force
Cos X is the angle between the two forces.
On further simplifying the equation we get
degrees
Angle between the forces degrees
A and B are both correct answers, however with the statement of human cloning it does not lead to increased food production through biotechnology, so the only answer would be A
Answer:
ZBWCYAX
Explanation:
Equation for the intermediates: Z↔W↔Y↔X
1) B catalyzes the breakdown of Z, therefore inhibiting B leads to the build up of Z.
2) If enzyme C is inactive then the organism will not receive Y to grow, thus Y is a by-product of C.
3) If A is inhibited then W, Y and Z build except for X, thus it make sense that A catalyzes a reaction that leads to X as a by-product.
4) Inhibiting C leads to the reaction toward making Z and W, thus it catalyzes the breakdown of C directly and Z indirectly.
