Ghella [55]

Answer:

This question is incomplete, it is asking to identify the following variables in the question:

Independent Variable: DIFFERENT AMOUNTS OF OIL

Dependent Variables: NUMBER OF KERNELS THAT POPPED

Controlled Variables: TIME FOR POPPING, SAME BRAND OF KERNEL, SAME COOKING TIME

Explanation:

The independent variable of an experiment refers to the variable that the experimenter intentionally manipulates or changes for the purpose of effecting a measurable response in another variable (dependent variable). In this experiment, the independent variable is DIFFERENT AMOUNTS OF OIL used because this is what Jason changes in the experiment.

Contrarily, the dependent variable is the variable that the experimenter measures in response to the independent variable. In this experiment, Jason measures the NUMBER OF KERNELS THAT POPPED from using different amounts of oil. Hence, the NUMBER OF KERNELS THAT POPPED is the dependent variable.

Controlled variables or constants are those variables that must be kept constant or unchanged throughout the experiment in order not to influence the findings of the experiment. In this case, the following variables were kept constant for all the groups: TIME FOR POPPING , SAME BRAND OF KERNEL (Pop rite), SAME COOKING TIME (4 mins).

explain how a toxin in a food web will harm some while killing others why did the mosquito and cats die while other things lived
vladimir1956 [14]
I think that a toxin that was introduced into a food web can kill some species but not others because some may have resistances to the toxin, while others, it may be lethal. Also that it did not affect everyone because as Bioaccumulation has stated if affected one organism but their might not be much biomagnification as in much increase in the correlation between the food chains in that area. i think the cat were like the top animal so the key stone animal of the food chain and also it had no predators.
