Some chemicals increase the mutation rate, physical agents such as radiation also increase the mutation rate. There are viruses that are mutagens as well. Also, the number of mutations that an organism produce can also be phenotypically plastic.
Hope this helps. (This is the definition my bio teacher gave me.)
As it gets colder, the molecules get less dense which causes it to get smaller.
I have never heard of the four phases of research, but I know that the scientific method can be summarized in four steps.
1. Observe something in nature.
2. Make a hypothesis (prediction) based on that observation.
3. Design and undergo and experiment to test the validity of your hypothesis.
4. Draw a conclusion about your hypothesis based on the results of your experiment.

The structure of lipids is dominated by hydrophobic regions
Lipids are fatty, waxy, or oily compounds that are soluble in organic solvents and insoluble in polar solvents such as water. Lipids include: Fats and oils (triglycerides) Phospholipid
The most abundant membrane lipids are the phospholipids. These have a polar head group and two hydrophobic hydrocarbon tails
