- 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.

The first land plants appeared around 470 million years ago, during the Ordovician period, when life was diversifying rapidly. They were non-vascular plants, like mosses and liverworts, that didn't have deep roots

Na (sodium), because alkali metals are not found freely in nature due to their high reactivity. (In this group are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).
        
             
        
        
        
Correct answer: D) Loss of insulation around vital organs
Fat is a nutrient should be to be taken in the diet but not in excess amount, it provides energy and help the body to absorb the vitamins.
It consists of a hydrocarbon chain and served to provide the structural and functional unit of the cell. The cell membrane is made up of a  phospholipid bilayer, which consists of phosphate and glycerol.
The main function played by the fat inside the body include the transformation of energy and providing heat insulation to the body.
The adipose tissue of the body act as an insulator. As it contains fat molecule, and fat is a poor conductor of the heat, it traps the heat across the vital organ of the body such as heart, eyes etc. Due to the bad conductivity, fat molecule act as an insulator. It also acts as a cushion for most of the important organ of the body and protects them from damage and mechanical injury.
