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.

The relationship between the bird and tree would be considered commensalism. That's when two organisms both receive an increase because of their relationship.
Hope that helps,

Alternative energy sources are those that do not deplete natural resources and do not harm the environment.
Options A, B, and C are all fossil fuels, which we know can be depleted and harm the environment.
The only valid option here is D, Geothermal energy.
Geothermal energy is both renewable and environmentally friendly.

<em>Several scientists make the same observations about the effect of sunlight on algae. This set of observation is called Working theory. ... The study of algae is called phycology or algology. The term shields a variety of photosynthetic creatures, and many are not narrowly related.</em>
They would fight over water and nutrients and most importantly sunlight as both will be around the same height and also would want space but again the giraffe will eat the trees leaves and it will later die so it’s basically like survival of the fittest
