Answer:
a) It is dangerous to wear nylon clothes while cooking because it is a synthetic cloth and they catch fire easily also they can stick on our body which is very painful.
b) Cotton is a natural product. And unlike synthetic fibres, it is more absorbent. The towel hence has high absorbency.
c) Nylon and polyester are two fabrics most commonly used in raincoats and umbrellas. They are not absorbent the way natural fibers are. They naturally resist waterlogging, and can be made waterproof.
Answer:
The eukaryotes, bacteria, and archaea that live in and on the human body are called normal microbiota. When they were originally discovered, scientists thought that the relationship between these organisms was parasitic because they thought that the organisms benefit from living on the host but did not help the host. In recent years, researchers have determined that most of our resident microbes derive and give benefit to the host. This makes the relationship between host and microbe one of mutualism. Pathogenic, on the other hand, are microbes that cause diseases.
Answer:
Perichondrium
Explanation:
Elastic cartilage (like hyaline cartilage) has chondrocytes located in lacunae and the tissue is surrounded by a perichondrium. The perichondrium (Figure 7–2) is a sheath of dense connective tissue that surrounds cartilage in most places, forming an interface between the cartilage and the tissues supported by the cartilage. The perichondrium harbors the blood supply serving the cartilage and a small neural component. Articular cartilage, which covers the ends of bones in movable joints and which erodes in the course of arthritic degeneration, lacks perichondrium.
