A shortage occurs when demand exceeds supply – in other words, when the price is too low. However, shortages tend to drive up the price, because consumers compete to purchase the product. As a result, businesses may hold back supply to stimulate demand.
Even though the Phillips curve is an empirical model has historically shown that the rate of unemployment and the rate inflation is inversely proportional, this is only observed in the short-run. In a graph, this is shown as non-linear.
The Long-run Phillips curve, on the other hand, is linear. This means that there's no constant trade-off with regard to inflation & unemployment.
Answer:
The correct answer are: Hypodermis and subcutaneous layer; areolar and adipose tissue; stabilizing position of the skin.
Explanation:
- The hypodermis, also called subcutaneous tissue, or superficial fascia, is the lowest layer of the integumentary system in vertebrates. The types of cells found in the hypodermis are fibroblasts, fat cells and macrophages. It derives from the mesoderm, but unlike the dermis, it does not derive from the dermatome in the region of the mesoderm. The hypodermis is mainly used to store fat.
- Areolar connective tissue: It is one of the most widely distributed. It contains cell types such as fibroblasts, macrophages, plasma cells, mast cells and white blood cells. It consists of collagen, elastic and reticular fibers. The main substances it contains are hyaluronic acid, chondroitin sulfate. This type of tissue is part of the subcutaneous tissue.
- Adipose tissue: It is composed of a cell type called adipocira that store triglycerides. It is associated with areolar tissue. It acts as an insulator to prevent heat loss. It is the main source of energy and provides support and protection to various organs.
