the three distinct phases of an action potential occur in what order?

Answers

Answer 1

The three distinct phases of an action potential occur in the following order: the depolarization phase, the repolarization phase, and the hyperpolarization phase.

Action potentials propagate a signal along the length of an axon differently in myelinated versus unmyelinated axons. Myelin, a lipid-rich membrane sheath surrounding some axons, insulates against the flow of ions. An action potential has three phases: depolarization, overshoot, and repolarization. There are two more states of the membrane potential related to the action potential. The first one is hyperpolarization which precedes depolarization, while the second one is hyperpolarization, which follows repolarization.

while jogging, a person has a stroke volume of 130 ml/beat and a heart rate of 120 beats per minute. if their resting stroke volume was 70 ml/beat and resting heart rate was 60 beats per minute, how did this person's cardiac output change?

Answers

The person's cardiac output increased from 4.2 L/min at rest to 15.6 L/min while jogging, due to an increase in both heart rate and stroke volume.

Cardiac output is the amount of blood pumped by the heart per minute and is calculated by multiplying stroke volume (the amount of blood pumped per heartbeat) by heart rate.

Resting cardiac output of the person can be calculated as:

Cardiac output = Stroke volume x Heart rate = 70 ml/beat x 60 beats/min = 4200 ml/min

During jogging, the person's cardiac output can be calculated as:

Cardiac output = Stroke volume x Heart rate = 130 ml/beat x 120 beats/min = 15,600 ml/min

The person's cardiac output increased from 4200 ml/min at rest to 15,600 ml/min during jogging, indicating that their heart is working harder to pump more blood to meet the increased demand of the body during exercise.

if body fluids are separated from pure water by a permeable membrane,

Answers

When body fluids are separated from pure water by a permeable membrane, osmosis occurs, causing water molecules to move across the membrane from the pure water side to the body fluids side.

Osmosis is a passive process that involves the movement of water molecules across a selectively permeable membrane, like the one separating body fluids and pure water in your question. The purpose of this process is to balance the solute concentrations on both sides of the membrane. Since body fluids contain a higher concentration of solutes than pure water, water molecules will move from the pure water side (where there's a lower solute concentration) to the body fluids side (where there's a higher solute concentration) to achieve equilibrium. This continues until the concentrations are equal or the pressure difference (osmotic pressure) counteracts the movement of water molecules.

a drop of food coloring spontaneously distributes throughout a container because

Answers

A drop of food coloring spontaneously distributes throughout a container because of the process of diffusion. In this process, molecules naturally move from areas of higher concentration to areas of lower concentration until a uniform distribution is achieved.

Molecular collisions lead the food coloring molecules to move erratically about the glass as they start to interact with the water molecules. The molecules diffuse throughout space as the collisions go on. Diffusion, or the transfer of particles from a region of high concentration to a region of low concentration, is the process by which a drop of food coloring spontaneously disperses across a container. The molecules eventually filled the space, became uniformly dispersed, and covered the entire glass. The presence of spreads, such as water or other liquids, in the container, facilitates this process, which is caused by the food coloring's molecules moving at random. The food coloring particles spread evenly across the container as they move and interact with the spread's particles, giving the container a consistent color.
