Answer:
Without naturally occurring greenhouse gases, Earth's average temperaturewould be near 0°F (or-18°C) instead of the much warmer 59°F (15°C). The concentration of greenhouse gases, especially carbon dioxide and methane, has fluctuated naturallyover geological time scales.
Answer:
Natural forces don’t have a strong effect on recent global temperatures. The natural forces line begins to drop around 1950 and does not track with the observed temperature line. On the other hand, the human effects line rises upward with the observed temperatures, so it’s a stronger effect. Solar radiation falls into the category of natural forces.
Explanation: This is the exact answer so I recommend changing it up a little bit. :)
True. Alluvial fans, deltas, and deposition are examples of land formations that are formed from deposits by rivers.
During active transport, the sodium pumps would transfer the solutions opposite the concentration gradient. This means that it would go from Solution A to Solution B
Cell is limited in size for many reasons. Cells wouldn't be respire effectively if it were too large, because the surface area to the volume ratio would be too small.
The other thing is that if the cell were too large, it would be difficult for it to move nutrients and waste products in and out of the cell. So, cells are limited in size.
