Answer:
3 materials
Explanation:
The jacket and trousers worn by a firefighter have to be constructed from materials that will withstand intense heat. Aramid fiber is a synthetic fiber that is highly regarded for its strength and heat resistance. Nomex is the trade name for arimid fiber clothing, and this type of material is used in the construction of a firefighter jacket and trousers. Nomex is often combined with Kevlar to increase the strength of the material.
Answer:
derived trait
Explanation:
An ancestral (or primitive) trait/character is a feature inherited from the common ancestor of the species/group of interest, while derived traits are those that were absent in the last common ancestor of the group of interest. For example, considering mammals as the target group, the presence of hair is a shared derived trait relative to other vertebrates, i.e., amphibians, reptiles and birds. However, this trait (hair) is ancestral for humans since the genetically closest species to humans (e.g., chimpanzees), also have hair, and they have inherited this trait from a common ancestor.
Answer:
Reptiles have scales, and their skin is dry. Amphibians do not, and their skin is often moist with mucus, which keeps them from drying up.
