Final answer:
In perfect competition, many sellers participate as price takers, there's free entry and exit in the market, products are identical, and complete information is available to all market participants.
Step-by-step explanation:
Characteristics consistent with perfect competition include several key features. Firstly, there must be many sellers and buyers in the market, each too small to influence the market price, leading to the fact that sellers are price takers. Secondly, there is easy entry and exit into the market for firms, meaning there are no significant barriers preventing new firms from competing or existing firms from leaving. Thirdly, all products in a perfectly competitive market are identical, also known as homogeneous, which means consumers do not prefer one product over another based on brand or quality. Lastly, all parties in the market have perfect information, enabling them to make well-informed decisions about their buying and selling activities. These conditions result in a market in which no single firm can influence the market price or terms for exchange, which is the essence of perfect competition.
