Introduction: Neurons are specialized cells that help collect external information, analyse the information and respond to it. Neurons make up a large signaling network known as the nervous system in the body.
Explanation of Solution
Many axons have a lipid coating called myelin, forming an isolating layer called a sheath around the axon. The myelin sheath has several gaps along the length of the axon called nodes.
A threshold is the minimum opportunity to allow action potential to be generated.

- The metabolic pathway below is used for the production of the purine nucleotides adenosine monophosphate (AMP) and guanosine monophosphate (GMP) in eukaryotic cells. Assume each arrow represents a reaction catalyzed by a different enzyme. Using the principles of feedback inhibition, propose a regulatory scheme for this pathway that ensures an adequate supply of both AMP and GMP, and prevents the buildup of Intermediates A through G when supplies of both AMP and GMP are adequate.arrow_forwardQUESTION 27 Label the structures marked A, B, C and explain the role of structure A.

We will use a different type of graph to derive additional information from the CO2 data (Fig A1.6.2) 1. Calculate the average rate of increase in COz concentration per year for the time intervals 1959-1969, 1969- 1979, etc. and write the results in the spaces provided. The value for 1959-1969 is provided for you as an example. 2. Plot the results as a bar graph. The 1959-1969 is plotted for you. 3.

- San Andreas Transform Boundary Plate Motion The geologic map below of southern California shows the position of the famous San Andreas Fault, a transform plate boundary between the North American Plate (east side) and the Pacific Plate (west side). The relative motion between the plates is indicated by the half arrows along the transform plate boundary (i.e., the Pacific Plate is moving to the northwest relative to the North American Plate). Note the two bodies of Oligocene volcanic rocks (labeled Ov) on the map in the previous page located along either side of the San Andreas Fault. These rocks are about 23.5 million years old and were once one body of rock. They have been separated by displacement along the fault. 21. Based on the offset of these volcanic rocks, what is the average annual rate of relative plate motion in cm/yr?
