If it is for Odesseyware the answer is all industrial nations.
The two main variables in an experiment are the independent and dependent variable.
An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable.
A dependent variable is the variable being tested and measured in a scientific experiment.
The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.
For example, a scientist wants to see if the brightness of light has any effect on a moth being attracted to the light. The brightness of the light is controlled by the scientist. This would be the independent variable. How the moth reacts to the different light levels (distance to light source) would be the dependent variable.
When results are plotted in graphs, the convention is to use the independent variable as the x-axis and the dependent variable as the y-axis.
A hypothesis is a suggested explanation for an observable problem OR a reasoned prediction of a possible causal correlation among multiple problems. A theory is a tested and well substantiated and unifying explanation for a set of verified and proven factors.
Answer:
Environmental impacts of particles, such as dust and smoke, released from livestock production - impair the visibility, can lead to acid rain, degrade the ecosystem
Environmental impacts of greenhouse gases released from livestock production - increase in atmospheric temperature
Explanation:
Environmental impacts of particles, such as dust and smoke, released from livestock production -
Release of particles such as dust and smoke is referred to as particulate pollution. These particle makes the air unfit for .breathing. If humans inhale it, it will adversely affect the heart and lungs.
These particle impair the visibility, can lead to acid rain, degrade the ecosystem etc.
Environmental impacts of greenhouse gases released from livestock production -
Green house gases will lead to increase in atmospheric temperature
