As a result, water will flow across the cell membrane into that cell (down its concentration gradient) from the surrounding environment eventually causing the cell to swell and burst (c). Hypertonic â refers to a solution that is higher in solutes than that inside of a cell.
The scientific evidence is clear. Within the scientific community, there is no debate. An overwhelming majority of climate scientists agree that global warming is happening and that human activity is the primary cause.
To come to a conclusion on climate change, the United Nations formed a group of scientists called the Intergovernmental Panel on Climate Change, or IPCC. The IPCC meets every few years to review the latest scientific findings and write a report summarizing all that is known about global warming.
