Facilitated transport refers to a type of transport which does not require energy to occur. An example of facilitated transport is faclitated diffusion in which molecules just diffuse from one point to another across a membrane. For instance, glucose use facilitated transport to move in and out of cells.
Active transport refers to a type of transport in which energy is needed for it to occur. Example is the uptake of glucose in the small intestines of humans.

Disadvantages of synthetic rubber
Explanation:
A synthetic rubber is an artificial elastomer made from polymerization of various monomers and an alternative for natural rubber. Although the synthetic rubber can be recycled and has some advantages over natural rubber, there are also some disadvantages like:
- The mechanical properties are not that strong compared to natural rubber
- The tearing resistance is lesser than natural rubber especially when hot
- Tensile strength is lesser than natural rubber
- Lesser overall dynamic performance
- Damping level is high
- During flexing, there is more heat built-up
It has the strongest winds in the solar system
Its orbit was used to predict the existence of another planet
It is most well-known for its rings
It has a giant storm three times the width of Earth.
