Can someone help me with this I am confused

When your Math teacher was handing out the test, you noticed that your respiration rate and heartbeat increased, your palms got

Papessa [141]

Answer:

My pretest behaviors were triggered by the sympathetic nervous system, while my body returned to its normal state by the way of the parasympathetic nervous system, after the test.

Explanation:

The sympathetic nervous system and the parasympathetic nervous system are part of the autonomic nervous system. The main function of the autonomic nervous system is to regulate the heart, kidneys, and liver which are not under voluntary control. The regulation of the body’s unconscious actions is executed through the sympathetic and the parasympathetic nervous system.

Upon exposure to stressors or threats, the sympathetic nervous system is triggered. Epinephrine and norepinephrine are then released, causing acceleration of the heart, constriction of blood vessels, increase in blood pressure, profuse sweating and other related responses against stress. The sympathetic nervous system controls all these involuntary responses that could be termed “fight-flight-or-freeze” response.

On the other hand, the parasympathetic nervous system initiates what is termed “rest and digest” response, which occurs immediately after the “fight-flight-or-freeze” phase response to stress is over. The body is returned to its normal state by the parasympathetic nervous system. The parasympathetic nervous system releases acetylcholine, which regulates the function of the body during a period of rest or recuperation.

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.
