They can look at previous data and compare it to current data of the climate, from there they can estimate climate change. Example: in 1977on july 23rd the temperature was 28°C. on july 23rd 2017 the temperature was 32°C. the temperature in 40 years the temperature changed by 4°C

Part 1:
A solution that causes a cell to swell is a hypotonic solution.
In an isotonic solution, there is no change in the size of the cell.
All three cause osmosis.
A solution that causes a cell to shrink is a hypertonic solution.
Part 2:
1. H. Energy
2.D. Endocytosis
3.G. Diffusion
4.B. Exocytosis
5.E. Facilitated Diffusion
6.A. Osmosis
7.C. Active Transport
8.F. Passive Transport
Sorry. I don't know how to explain part 3 ,but I tried and failed so I deleted it. Part 1 and 2 are correct though.
