Ber [7]

The key difference between command and market economies is that: Households answer the basic economic questions in a market economy, while a group of leaders answer them in a command economy.

<h3>Types of economy.</h3>

Generally, there are five (5) main types of economy and these include the following;

  1. Mixed economy.
  2. Command economy.
  3. Traditional economy.
  4. Pure capitalism economy.
  5. Underground economy (black market).

<h3>What is a market economy?</h3>

A market economy is also referred to as free-enterprise system or free market and it can be defined as a type of economy in which prices, products and services are being determined by the market rather than the government.

This ultimately implies that, a market economy is devoid (free) of government regulations, interference or control because the market is completely driven by demand and supply of goods and services.

Which statement best explains the orientation of the phospholipid molecules in this model?
igomit [66]

Answer:

B• The hydrophilic phosphate groups of the phospholipid molecules are attracted to the aqueous internal and external environments.

Explanation:

Hello, you did not put the model to which this question refers, but I can say that the letter B is the correct answer, due to the composition that the phospholipids present.

Phospholipids are a molecule formed by two tails of hydrophobic fatty acids, that is, they do not come into contact with water, and a type of "head" that is a hydrophilic phosphate group, that is, it allows contact with water.

When a molecule formed by phosphate groups is found in an aqueous medium, it is common for the hydrophobic tail to be attracted to the inner corner of the molecule, preventing contact with water, while the hydrophilic part faces the outer side of the molecule.
