The serotonin binds to a G-protein -coupled receptor and activates a G-subunit . This results in activation of PKA and closing of the potassium channels. This will subsequently decrease the influx of potassium ions into the cell, and lead to depolarization of the cell. This changes the membrane potential of the cell.
Aplysia are sea slugs which fall under the category of mollusks. Serotonin is a hormone which is responsible for the transfer of electrical signals from the brain to different parts. In this particular mollusk, serotonin was studied to find that it is an essential neurotransmitter that is responsible for the maintenance of synaptic plasticity in the neurons. Synaptic plasticity is the feature which is essential for the communication of neurons. This is the modification which occurs at the synapses during the transmission of synapses. Without this activity, the transmission of signals would be impossible.

Answer:Photosynthesis is the process by which plants use the energy of sunlight to make sugar (glucose) from carbon dioxide and water. Respiration is the process by which animals use O2 to get energy from food. So plants take in CO2 from the air and produce O2, and animals take in O2 from the air and produce CO2.
Explanation:
Answer:
Please find how the population will be affected by each interaction below
Explanation:
1.) Competition: Competition is a kind of interaction which harms both of the organisms involved. It is caused when organisms of different species share the same resource in an ecosystem. Competition between species of two populations will cause BOTH POPULATIONS TO BE AFFECTED.
2.) Predation: Predation is another kind of interaction in which one organism called the PREDATOR feeds on another organism called PREY. The populations of one species will PREY on the population of the other species, hence, one population will be affected.
3) Mutualism is the interaction between organisms in which both species benefit from one another. Hence, the population of the two species are affected POSITIVELY by this interaction.
