Environmental variables such as light, water, temperature, soil nutrients, and humidity can influence plant growth. Each student should control these variables to promote healthy plant growth, by providing adequate sunlight, water, nutrients, and maintaining appropriate temperature and humidity levels. Monitoring and adjusting these variables will help ensure successful plant growth in each student's experiment.
There should be one dependent variables. Depending on the type of research you are doing, the amount of independent variables will change. If you are doing research on a large scale, you will use more independent variables. If it's on a small scale, you will use very little. If you are not able to run your regression it means your sample size is too small or you have too many independent variables.
The number of variables in a hypothesis test typically depends on the research question being addressed and the complexity of the relationship being studied. In general, it is recommended to include only the necessary variables that directly relate to the hypothesis being tested to minimize confounding factors and improve the clarity of results.
Humidity is separate from temperature, and "should" is ambiguous in this case.
Compost should be maintained at a temperature between 110-160F for optimal decomposition.
All accident should be investigated.
should all variances be investigated
Static variables (should) remain the same e.g. temperature of a water bath, k constant of a particular spring. Dynamic variables change as the experiment progresses e.g. air temperature and pressure, amount of natural light.

Some controlled variables when using a lemon for an experiment could be its size, ripeness, temperature, and the method of extraction of the lemon juice. These variables should be kept constant throughout the experiment to ensure that any changes observed are due to the manipulated independent variable and not these controlled variables.

all.
All types of accidents should be investigated in order that they can eventually be prevented. Certainly any accident that involves injury or destruction of property should be evaluated for cause.
In an experiment, variables that must be kept constant are called control variables. Two common examples include temperature and pH levels. These variables should be kept constant to ensure that any changes observed in the dependent variable are a result of the independent variable being tested.
