Define and explain the greenhouse effect. (What is it and how does it occur in detail?)

Gases in Earth's atmosphere traps the Sun's heat. These are called greenhouse gases.

Explanation:

Sample Response: The greenhouse effect is a natural process by which the Earth’s surface and lower atmosphere are warmed by certain gases in the atmosphere, helping to maintain the normal range of temperatures on Earth. The energy released by Earth’s surface is absorbed by greenhouse gases in the atmosphere. These gas molecules then re-release some of this heat back toward Earth’s surface, warming it. The greenhouse effect is important because it allows life to exist on Earth by maintaining an average temperature that supports life.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
