Answer:

When the electrons jump to a higher energy state, they release energy as electromagnetic radiation, light.

Explanation:

When the solar wind gets past the magnetic field and travels towards the Earth, it runs into the atmosphere. As the protons and electrons from the solar wind hit the particles in the Earth's atmosphere, they release energy – and this is what causes the northern lights.

What is the dependent variable in an experiment testing the effects of pH on growth of a seed?
dimulka [17.4K]

The correct answer is A. Seed growth

Explanation:

Experiments often involve two main variables: the independent variable and the dependent variable. In an experiment, the dependent variable is always the main factor being studied; also, this is "dependent" because it is affected by other factors. In the case presented, the dependent variable is seed growth because this is the specific phenomenon that is being analyzed. Moreover, this factor is affected by the changes in pH. On the other hand, the pH, which is the second factor is the independent variable because this is not affected by the first variable and it is manipulated on purpose.
