Learning objective: 12.08.05 describe the initiation and propagation of depolarization and repolarization.

denis-greek [22]

Depolarization is initiated when there is an influx of sodium inside the cell as opposed to repolarization, where potassium exits the cell (occurring after Na+ gates close). Remember that for every 3 Na+ in, there is 2 K+ out. This imbalance helps to stabilize the membrane.

The term for energy of movement

lara31 [8.8K]

Answer;

-Kinetic energy

Explanation;

The energy associated with motion or movement is called kinetic energy.

-Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy is stored energy and the energy of position; gravitational energy.

-An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. Kinetic energy is calculated by the formula 1/2mv², where m is the mass of the object and v is the velocity of the object.

-Therefore, kinetic energy depends upon two variables: the mass (m) of the object and the speed (v) of the object.

1. What are the independent and dependent variables in each of the experiments?

Dafna1 [17]

The independent variables are temperature, airflow, and light and the dependent variable in each of the experiments is evaporation.
The schematic representation in the diagram helps in the understanding of the setup for the experiments.
The level of temperature, the rate of airflow, and the intensity of light must be controlled in the experiments.
A person will not be confident in experiment 3 results as the temperature is the independent variable that alters the results of evaporation.

<h3>What are the four foremost factors of a managed test?</h3>

When possible, scientists take a look at their hypotheses through the use of managed experiments. A managed test is a systematic take look at executed below-managed conditions, which means that simply one (or a few) elements are modified at a time, even as all others are saved consistently. We'll appear carefully at managed experiments within side the subsequent section.

In the three experiments, the dependent variable is evaporation, as it changes with the change in another variable.

The independent variable in experiment 1 is temperature, experiment 2 is airflow, and experiment 3 is light.

The experiment can be understood better with the representation of the schematic that shows the setup to analyze how the experiment was performed. Therefore the diagram must add the schematic of the experiment.

The controlled items in the experiment are the variables that are set at the particular unit to form the result. the controlled item in experiment 1 is temperature, experiment 2 is airflow from the fan, and experiment 3 is the intensity of light.

The result of experiment 3 is based on the dependence on the intensity of light keeping temperature constant and controlled. If the temperature is not controlled in the experiment then it may lead to an alteration in the results as it depends on both light and temperature.

The flow chart for the increase in pressure affecting the evaporation is given in the image attached.
