Answer: Hope This Helps!

Explanation:

1. The fall of Constantinople to the Ottoman Empire in 1453 was a pivotal reason for European exploration, as trade throughout the Ottoman Empire was difficult and unreliable. Trade for luxuries such as spices and silk inspired European explorers to seek new routes to Asia.

2. The triangular trade is known as a type of trade between three separate ports that serves to balance any imbalances produced between each of these three regions. The Atlantic Triangular Trade, for instance carried slaves, crops and manufactured goods from West Africa, America and the European colonizing countries.

3. France expected that Africa would always be part of France. They used an approach of assimilation which involved introducing their culture too Africa. Britain trained Africa to be self-governing. They were treated as self-governing entities with colonialists to govern them.

4. The slave trade had negative effects on Africa in both the short and long term. In addition to displacing a significant percentage of the population, the slave trade encouraged African nations to wage war and disrupted local cultures and economies. This destabilized the region as a whole and made it almost impossible for African countries to industrialize, which in turn made the nations of Africa far more susceptible to European colonization and exploitation.

Variable-ratio                    

Explanation:

Variable-ratio schedule: In psychology, the term "variable-ratio schedule" is described as one of the different reinforcement schedules in the operant conditioning theory which was proposed by B. F. Skinner. In the variable-ratio schedule, a specific response is being reinforced after an "unpredictable or unforeseeable number" of responses. However, the variable-ratio schedule creates a steady yet high rate in terms of response.

Example: Gambling.

In the question above, the given statement represents a variable-ratio schedule.

lara31 [8.8K]

The concept of social facilitation is so named because of the idea that when the presence of others is arousing, "this arousal facilitates a well-learned, dominant response".

<h3>What is social facilitation?</h3>

The tendency for the presence of others to enhance a person's performance on a task is known as social facilitation.

Two types of social facilitation have also been defined: co-action effects and audience effects:

  • A co-action effect: is when your performance on a task improves simply because there are other people performing the same job as you. As an illustration, consider working alongside coworkers in an office setting as opposed to by yourself.
  • Audience effects: An audience effect is when your performance improves as a result of performing in front of a crowd. A pianist playing at home as opposed to performing in front of an audience is an example.

In addition, three more components are believed to play a role in social facilitation:

  1. physiological (drive and arousal),
  2. cognitive (distraction and attention), and
  3. affective (emotional) factors (anxiety and self-presentation).

Do you think myths or fables have a place in learning about history? Explain.
Assoli18 [71]

Myths, Fables, Legends, and Fairy Tales are all considered types of stories. Though they are all types of stories, they have some key differences. A myth is a traditional story that is used to explain a belief or perspective of the world. They are often used to provide a reason for the way the world is, such as the myths about the Greek gods. Each was a god of a particular part of nature or idea. They were said to be the reason that part of nature existed. A legend is a story that has been passed down through generations via oral storytelling. They are usually stories about real people, places, and events of the past. The facts within these stories are known to be somewhat exaggerated. A fable’s overall purpose is to teach a lesson or a moral using characters that cannot talk in real life (such as animals, plants, and forces of nature). Fairy tales are stories for children that often include a magical or supernatural element, such as elves, witches, or special animals. These stories most often begin with the phrase Once upon a time.
