Answer:
Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat-trapping causes changes in the radiative balance of the Earth-the balance between energy received from the sun and emitted from Earth-that alter climate and weather patterns at a global and regional scale.
Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years. Natural Factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.

Answer:
3 AND 6
Explanation:
think of the plate as a clock and the serving of vegetable is in 1 corner of the plate. the plate has 4 corners
- 12 to 3
- 3 to 6
- 6 to 9
- 9 to 12
The only answer can be 3 to 6
Normally, when a cell dies, the outside morphology changes, in other words, the cell looks different. For example, if you are growing cells that attach to a plate, when they die they are not able to attach to the bottom of the plate anymore, and they will appear floating in the medium. I am not sure of what kind of cells you are studying; if you told us it would help as to suggest ways of distinguish between live/dead cells.
So you want me to create environmental slogans or is this a question?
