The clear fluid in the acne after it has been squeezed is that it has the role of exudating. It is the mass of cells in forms of fluid and the role of it in the wound is to help the wound to heal and clean when the blood vessel open the area, and after the fluid has been exudated, the nutrients and the oxygen that is needed by the wound would be brought by the blood of the individual.
Answer:
The procedure is given below.
Explanation:
First we record the data of the pollutants that is releasing from the factory. Record the population of the coral reef which are not affected from these pollutants then take the data again and record the population of coral reef that is affected from the pollutants. If the population of coral reef that is affected from that pollutants increases it means that the pollutants damaged the coral reef population at higher rate. The purpose of this lab is to find out the negative effects of pollutants that is released from the factory on coral reef.
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.
