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

gth of the axon b) the number of axon collaterals extending from a truncated axon c) degree of myelination of the axon d) whether the axon is located in the central nervous system or in the peripheral nervous system

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.

A simple diagram of a DNA molecule is shown below. Which of the following is represented by X?
Reil [10]

Answer:

From the diagram X = <u>base pairs</u>

Explanation:

Genetic information stored within DNA is used for growth, reproduction, and cell repair. DNA, deoxyribonucleic acids, are long-chain, helical macromolecules made of specific sequences of covalently bonded monomers called nucleotides.

Nucleotides comprise:

  • a 5-Carbon deoxyribose sugar,
  • one nitrogenous base (adenine, guanine thymine, and cytosine)
  • and a phosphate group.

Nitrogenous bases cause nucleotides to form hydrogen bonds with other nucleotides as base-pairs. The four types of bases each make the nucleotides  Thymine and Cytosine (pyrimidine bases) along with Guanine,  and Adenine, (purine bases). In base-pair formation, Adenine forms double bonds with Thymine, and cytosine forms triple bonds with guanine.
