The image shows a phospholipid bilayer. Macromolecules that make up most of the structure that is shown are proteins and lipids. Lipids can make up 20% to 80% of the membrane depending on the location and type of the cell. The rest is made up of proteins.
The answer is; SET B
Polar molecules interact well with water because there are charged. Water molecules are partially charged (the oxygen end is partially negative while the hydrogen end is partially positive). Therefore polar molecules can interact stably with charged molecules. The hydrophobic end is non-polar and is ‘water-hating’. When mixed with water, the non-polar region clumps up into globules so they don’t interact with water.
Answer:
Metabolism - the chemical process within a living organism in order to maintain life
Explanation:
The common use it 'my metabolism is really slow/fast', usually heard in fitness and diet communities. The biggest difference is that, while metabolism does deal with the burning of energy from food, it really covers the processes using all materials such as water, food, nutrients, and oxygen in the cells to produce the body's energy.
