Agonists activate the receptor thereby <u>increasing</u> activity at the synapse while antagonists generally prevent agonists from activating the receptors thereby <u>decreasing</u> activity at the synapse.
- An agonist is the component that has the ability to increase the activity carried out by another substance.
- The agonists work from their faculty of coupling to a cell-type receptor, in this way, they manage to generate a certain action in the cell.
- The antagonists are the compounds that cause the opposite when they bind to the receptor, they cause a blockade by decreasing the activation of a synaptic receptor.
Therefore, we can conclude that agonists are compounds capable of increasing the action of synapse and blockers (antagonists) decrease activity at the synapse.

Answer:
Photoperiodism
Explanation:
The term "photoperiodism" was coined to describe a plant's ability to flower in response to changes in the photoperiod: the relative lengths of day and night. Because flowers produce seeds, flowering is crucially important for the plant to complete its life cycle.
Answer:
Either producer or decomposer
I believe that the correct sequence of stages in the General adaptation syndrome from the first to last is Alarm, resistance and then exhaustion. The general adaptation syndrome describes stages in the body's response to prolonged stress. According to Hans Selye there are three predictable stages the body uses to respond to stressors. The first stage is the alarm stage, which provides a burst of energy, the second stage called resistance change, the body attempts to resist or adapt to the stressor and lastly the exhaustion stage.
