Answer:

The correct answer would be a. improves.

Wildfires are natural and often a necessary event of the ecosystem.

It helps in improving the quality of the soil in various ways:

It helps in clearing the thick underbrush growth and thus enables the sunlight to reach the forest floor which encourages the growth of native species.

It increases the fertility of the soil by increasing the mineral and nutrient contents of the soil. It does so by converting the dead plants and animals chemically into more available forms.

3. The time between the end of ventricular systole to the beginning of atrial systole.

amid [387]

Answer:

The time between the end of ventricular systole to the beginning of atrial systole is 100 ms or 0.1 seconds.

Explanation:

Ventricular systole is the removal of blood from the heart by pumping through aorta and pulmonary vein. Both aorta and pulmonary vein receive the blood from the heart. Aorta receives oxygenated blood and pulmonary vein receive deoxygenated blood, while atrial systole is the addition of blood into the ventricular from vena cava and pulmonary artery due to contraction of heart. This process occurs in 100 ms.

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.
