Insulin and glucagon. Insulin stores simple sugars in the form of a polymer (glycogen) in the liver and glucagon breaks down glycogen in the liver forming glucose and releases it back into the bloodstream. ChaCha!
Antagonism is the process by which two hormones exert opposite effects.
The presence of other hormones, especially auxins, influence the effects of cytokinins.
Synergists
Antagonism is the term that you are looking for. It helps to keep this in balance and acts under the concept of homeostasis.
growth hormone and thyroxine
Growth Hormones but they have side effects.
its what happens when a drug decreases the effect of another drug
Reactive force. For every action there is an equal but opposite reaction. So if a box is sitting on the table, and the box weighs one kg, it exerts 9.81N of force on the table. Likewise, the table exerts 9.81N of force on the box in order to keep the box on the table. Otherwise, the box would smash through the table. THESE TWO FORCES ARE EQUAL BUT OPPOSITE, SO THE SUM OF THE TWO WILL ALWAYS BE EQUAL TO ZERO.
From Newton's third law, when two bodies A and B collide, the force that A exerts on B is equal in magnitude but opposite in direction to the force that B exerts on A. From Newton's second law, this force produces a rate of change of momentum. Both bodies are experienced to the same magnitude in change of momentum but in opposite directions. Net change in momentum is zero. This implies that momentum is conserved.

Erm..yes. Technically Newton's 3rd law of Motion States that, " all forces exist in pairs: if one object A exerts a force FA on a second object B, then B simultaneously exerts a force FB on A, and the two forces are equal and opposite."
If you are referring to taking two pills from your packet of BC pills, the adverse effects could be break through bleeding, nausea, bloating and breast tenderness. The hormones mimic the hormones of pregnancy - the side effects would most likely be similar to early pregnancy. I would suggest this is not something you want to do frequently - there is no reason to double up on oral contraception.
