Problem:Myelin is a lipid-rich (fatty) substance formed in the central nervous system (CNS) by glial cells called oligodendrocytes, and in the peripheral nervous system (PNS) by Schwann cells. Myelin insulates nerve cell axons to increase the speed at which information (encoded as an electrical signal) travels from one nerve cell body to another (as in the CNS) or, for example, from a nerve cell body to a muscle (as in the PNS). The myelinated axon can be likened to an electrical wire (the axon) with insulating material (myelin) around it. However, unlike the plastic covering on an electrical wire, myelin does not form a single long sheath over the entire length of the axon. Rather, each myelin sheath insulates the axon over a single section and, in general, each axon comprises multiple long myelinated sections separated from each other by short gaps. Each myelin sheath is formed by the concentric wrapping of an oligodendrocyte or Schwann cell process around the axon.

Answer this question: the myelin sheath that covers many cns axons is formed by?
Solution:OK... The relevant information is: Each myelin sheath is formed by the concentric wrapping of an oligodendrocyte or Schwann cell process around the axon.
the concentric wrapping of an oligodendrocyte or Schwann cell process around the axon.

Student A:Passage: The Staten Island Ferry is a passenger ferry route operated by the New York City Department of Transportation. The ferry's single route runs 5.2 miles (8.4 km) through New York Harbor between the New York City boroughs of Manhattan and Staten Island, with ferry boats making the trip in approximately 25 minutes. The ferry operates 24 hours a day, 7 days a week, with boats leaving every 15 to 20 minutes during peak hours and every 30 minutes at other times. It is the only direct mass-transit connection between the two boroughs. Historically, the Staten Island Ferry has charged a relatively low fare compared to other modes of transit in the area; and since 1997, the route has been fare-free. The Staten Island Ferry is one of several ferry systems in the New York City area, and is operated separately from other systems such as NYC Ferry and NY Waterway.

Question: Based on this passage, how far is it from staten island to manhattan?
Student B:OK... This is the relevant information: The ferry's single route runs 5.2 miles (8.4 km) through New York Harbor between the New York City boroughs of Manhattan and Staten Island, with ferry boats making the trip in approximately 25 minutes.
5.2 miles ( 8.4 km ).

Problem:Passage: By convention, the three primary colors in additive mixing are red, green, and blue. In the absence of color, when no colors are showing, the result is black. If all three primary colors are showing, the result is white. When red and green combine, the result is yellow. When red and blue combine, the result is magenta. When blue and green combine, the result is cyan.

Question: Based on this passage, mix red and green to make this colour?
Solution:OK... The relevant information is: When red and green combine, the result is yellow.
yellow.
