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.

B. they are defined by their biotic factors and abiotic factors.
It is limited by it's surface area.
Answer:
In the given case, the most appropriate step to be taken by Brian in order to formulate the hypothesis is to visit other households with cats. In the given case, Brian has to confirm that whether he is allergic to cats or not, and for this, he must go on to find if a similar sneezing reaction is experienced when he is around other cats apart from aunt's cat.
It can be a case that some other environmental elements may have been resulting in the condition. Thus, wearing a mask would not help the cause straightforwardly as it would not confirm that Brian is allergic to cats.
