Which of the following is a factor that determines the rate of impulse propagation, or conduction velocity, along an axon?a) len
Alexxx [7]

Answer:

c) degree of myelination of the axon

Explanation:

Axon conduction velocity can be defined as the speed at which an electrochemical impulse propagates down an axon.

Factors that determines the rate of conduction velocity are:

  • axon diameter-larger diameter axons have a higher conduction velocity
  • sheeth-a myelin sheath increases the rate of impulse propagatio

Different types of neurons will have different speed of propagation because of their different properties and because different types of information are sent.

Scientists seeking to determine which molecule is responsible for the transmission of characteristics from one generation to the
worty [1.4K]
A) DNA fulfils all three conditions:
<span>(1) copy itself precisely - in the process of replication, DNA copies itself and two molecules of DNA are formed. This process is very precise thanks to the great number of proteins involved in these process that prevents error occurring and proteins that can fix the error if it occurs.
(2) be stable but able to be changed - DNA is very stable molecule otherwise, it cannot be a genetic material. However, its chains can separate in a short length so the translational machinery can attach to it and the process of transcription can occur. Also, in crossing over, during meiosis, </span>the exchange of genetic material occurs and chromosomes change a bit.<span>
(3) be complex enough to determine the organism’s phenotype - it contains a number of genes responsible for different traits. All of this results in the </span>organism’s phenotype.


B) DNA copies itself. <span>Meselson and Stahl conducted the experiments on DNA replication in which they used </span>E. coli<span> bacteria as a model system. After they labelled all bacteria's DNA with heavy 15N by using medium with heavy 15N, they switched bacteria to medium with light 14N. After several generations, all bacteria's DNA was labelled with light 14N. This experiment evidenced that the self-replication of DNA is semi-conservative process.</span>
