The animals that live in the Alpine biome have to have special adaptations to survive in it as this is a biome with very harsh conditions for big portion of the year. The temperatures are very low, the winds are strong, winter lasts for half a year or more, and there's lot of snow. All this has made the animals to develop certain traits to help them survive. Some of those adaptations are:
- thicker and longer fur for better isolation form the outside conditions
- wider paws with denser and tougher skin, helping them to move easier in the snow and avoid frostbite
- larger lungs and nostrils for easier breathing in the high altitudes
- stockier bodies so that heat can be preserved easier
- the ears and tails are small and rounded in order to avoid frost bite
- big portion of them are able to hibernate for several months
Ductility is a physical property.
A physical property of a material is a property that can be measured or observed without changing the composition of the material.
In this case ductility is a physical property. It is defined as the property of a material associated with the ability to be drawn or stretched into a wire without breaking. The chemical identity of the material is not affected, that is it does not change.
Example of ductile materials include gold, silver, copper, erbium, terbium and samarium.
Other examples of physical properties are:
1. Solubility
2. Melting point.
3. Boiling point.
4. Color
5. Density.

Answer:
Companion cell is a type of specialized parenchyma cell, which is located in the phloem of the flowering plants.
Each of the companion cell is usually associated with the sieve element. The main function of the companion cell is uncertain but it regulates the activity of sieve tube.
It plays a major role in the loading and unloading of the sugar molecules into the sieve element. As the sieve tubes do not have nucleus and ribosomes so they need companion cell to help in the transportation of sugar molecules.
