Shaping. Each step in the learning process is called an approximation. An animal may be reinforced for each successive approximation toward the final goal of the desired trained behavior. Animals learn complex behaviors through shaping.
When the ride is at the top of its pole, it has all potential energy. When it is in the middle, at 34 meters, it has 50% potential energy and 50% kinetic energy. When the ride is almost at the bottom, it has kinetic energy that turns into potential energy as it reaches the end.
Answer:
Paul has natural active immunity, while Nicholas has artificial active immunity.
Explanation:
Natural active immunity is an immunity that occurs when an individual is exposed to a disease causing organism, gets infected, and also become immune to the disease due to the primary immune response. From the question, Paul has natural active immunity because he had chicken pox before, and the virus that causes chicken pox has interacted with his immune response, hence, making him to develop natural immunity to the disease.
Artificial active immunity is an immunity that an individual acquires when small amount of immunity to a disease is deliberately exposed to his body. Artificial active immunity is usually produced in the form of vaccinations. From the question, Nicholas has artificial active immunity because chicken pox vaccines were intentionally introduced to his body.
Hydrogen is abundant in the sun.
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
