agonists generally _______ activity at the synapse while antagonists generally ______ activity at the synapse.
Agonists activate the receptor thereby increasing activity at the synapse while antagonists generally prevent agonists from activating the receptors thereby decreasing 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.

HELP!!! WILL GIVE MAX POINTS!! Doing a Lab Report on Natural Selection about beans. For example 20 dark red beans and 35 light red beans (kidney beans) Sample Response: When the volcano erupted, the dark red walking beans were easier to see. Thus, more dark red beans were eaten during days four, five, and six. If the pollution continued, there would be fewer and fewer dark red walking beans over time.
Questions being asked are:
1. What is the purpose of the lab?
2. What is your hypothesis for this experiment?
3. What methods are you using to test this hypothesis? (Outline the steps of the procedure in full sentences.)
4. 4. What graphs would clearly represent the trends in your data?
Your Student Guide includes information on which graphs to construct. Each graph should have the following items:
a. An appropriate title
b. Appropriate labels for each axis
c. An appropriate scale for each axis
d. The correct units for the data
Complete a rough sketch of each graph.
5. What do the data in your graphs tell you? (Explain in one or two sentences what trend is shown in each of your graphs.)
6. What does the data tell you about your hypothesis? (State how your hypothesis is either supported OR refuted by the data)
7. How does the data support your claim above? (Explain your statement above. Be sure to refer to specific pieces of data from your experiment that supports your argument)
8. 8. If you could repeat the experiment and make it better, what would you do differently and why?
There are always ways that experiments can be improved. Now that you are a veteran of this experiment and have experience with the procedure, offer some advice to the next scientist about what you suggest and why.
Answer:
During the days four through six the population of the dark red beans changed. The change was negative meaning that there was less dark red beans that light red beans. This happened because it was harder to see the light red beans because the color of the air changed. In result of that the zocco ate mostly dark red beans.

1. How do fossils form?
Explanation:
There is a LOOOONG process for this so here it is;
First things first.The animal dies. Soft parts of the animal's body, including skin and muscles, start to rot away. Scavengers may come and eat some of the remains. Before the body disappears completely, it is buried by sediment - usually mud, sand or silt. Often at this point only the bones and teeth remain. Many more layers of sediment build up on top. This puts a lot of weight and pressure onto the layers below, squashing them. Eventually, they turn into sedimentary rock. While this is happening, water seeps into the bones and teeth, turning them to stone as it leaves behind minerals. This process can take thousands or even millions of years.
I hope this answer helped. Thank you!
