The propagation of an action potential (AP) in an unmyelinated axon is called continuous propagation. This activity will test yo

ur understanding of the sequence of events that occur during continuous propagation.
Place the following events involved in the propagation of an action potential in the correct order of occurrence from left to right:
A) Voltage Gated Na+ channels open
B) Influx of Na+
C) Local current flows to axon segment
D) Axon segment depolarized to threshold
E) AP generated in adjacent axon segment

Dimas [21]3 years ago

Answer:

C, D, A, B, E

Explanation:

The sudden decrease or increase in the potential of cell membrane is Action potential. The stimulus (local current) allows change in the membrane potential, thus allowing depolarization of the membrane. This initiates the opening of Voltage Gated Na+ channels. The sodium starts entering the cell that is influx of Na+ and thus AP generated in adjacent axon segment. The sodium channels inactivates by membrane repolarization and activated pottassium channels allows the efflux of pottassium ions. The inactivation of potassium channels occurs by hyperpolarization ( low membrane potential) brings the membrane to its resting state. Thus, the correct order is C, D, A, B, E.

Lady bird [3.3K]

33% is the unknown concentration of the tube.

Explanation:

Concentration of stock of windex = 50%

concentration of bacteria = 500 microliter

nutrient broth = 1000 micro litre +500 microlitre of windex

concentration of bacteria is the volume of bacteria present in nutrient broth culture.

total volume in the tube is 1000

50% is the concentration of tube of bacteria and broth before adding windex.

After adding windex of 50 % concentration and the volume is 500 microliter which is only 250 microliter of windex rest is water.

33% is the concentration of the tube, which means it has 33% of bacteria in 1500 ml of solution.

E.Coli would be a good model organism to study how the cell membrane controls movement of substances in and out of cells?
hodyreva [135]

Answer:A.) True

Explanation:

E.Coli would be a good model organism to study how the cell membrane controls movement of substances in and out of cells because  it a eubacteria .Eubacteria characteristics include the ability to allow the movement of molecules across its membrane once a proton gradient is established , The membrane also has permeability enhancing properties that allow for the easy movement of substances.

Select the correct answer. Which statement correctly explains the polarity of the water molecule? A. The hydrogen end of the mol
Nuetrik [128]

Answer:

option B) The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge.

Justification:

The electronegativity of an element accounts for its relative ability to attract electrons.

Being oxygen more electronegative than hdyrogen (the electronegativity of oxygen is 3.44 while the electronegativity of the hydrogen is 2.20), the electron density will be displaced toward the oxygen, letting it with a partial negative charge and the hydrogen with a partial positive charge.

Finally, since the charge is not symmetrical distributed around a center of the molecule, the molecule ends being polar.
