The question is incomplete. The complete question is as follows:
Functions of astrocytes include all of the following, except
A) performing repairs in damaged neural tissue.
B) guiding neuron development.
C) functioning in action potential transmission.
D) maintaining the blood-brain barrier.
E) creating a three-dimensional framework for the CNS.
Answer:
Functioning in action potential transmission.
Explanation:
Astrocytes may be defined as the glial type star shaped cells present in the central nervous system. They envelope the synapse and can function with millions of neuron at a time.
Astrocytes are involved in the structural support in the brain and can repair the damaged and wear nerves tissue. Their main function is acting as blood brain barrier. The action potential transmission is mainly done by neurons and not by the astrocytes cells.
Thus, the correct answer is option (c).
Answer:
Light travels in straight lines.
Explanation:
Once light has been produced, it will keep travelling in a straight line until it hits something else.
Answer:
The correct answer is C) 1 L of 1.0 M NaCl
Explanation:
NaCl is a ionic compound so it dissociates in water into Na⁺ and Cl⁻ ions. Glucose is a covalent solute so it does not dissociates into ions. So, when we dissolve NaCl we have twice the amount of particles in solution in comparison with glucose. According to this:
A) and B) are solutions with the same concentration (0.5 M) but NaCl solution will have more solute particles than glucose.
C) and D) are solutions with more solute amount because they are more concentrated (1 M), but NaCl solution will have more solute particles than glucose solution ( 1 mol of Na⁺ ions + 1 mol of Cl⁻ ions).
The solution with the greatest solute particle number is C).
The term “carpetbaggers” refers to Northerners who moved to the South after the Civil War, during Reconstruction. Many carpetbaggers were said to have moved South for their own financial and political gains. Scalawags were white Southerners who cooperated politically with black freedmen and Northern newcomers.
hope this helped :)
