Final answer:
Synergism is when two or more things come together to produce an effect that is greater than the sum of the individual parts.
Step-by-step explanation:
The concept of synergism refers to a situation where two or more substances or elements come together to produce an effect that is greater than the sum of their individual effects. In biology, an example includes the synergistic effect between hormones. For instance, the reproductive hormones FSH (Follicle Stimulating Hormone) from the pituitary gland and estrogens from the ovaries have to work in tandem for the maturation of female ova (egg cells). Conversely, the antagonistic effect refers to components that produce opposing effects, such as insulin and glucagon, hormones which have inverse impacts on blood glucose levels.
