What are the three macronutrients?
1. Carbohydrates or "carbs", which are the body's main fuel source that gets easily broken down. 2. Protein, which is made up of amino acids, provides the building blocks for muscle and supporting other important structures such as hair, skin, nervous system, blood, brain and more. 3. Fats, also known as lipids, play a role in providing energy for the body, making hormones, helping fat-soluble vitamins absorb into the body, and providing insulation.
What's the difference between their, they're and there?
"Their" is when you are referring to something that belongs to someone, and can be described as a third person possessive adjective (e.g., "That's their favourite store"). "They're" is simply a contraction of "They" and "Are" (e.g., "They're going to their favourite store") "There" has many different uses, and is used in all other cases not mentioned above (e.g., "There is a store.", "Look at that store over there!", "We went there yesterday.")
What is the difference between operant conditioning and classical conditioning?
Operant conditioning is when voluntary behaviour is either reinforced or punished which subsequently increases or decreases behaviour. Classical conditioning is when you pair a neutral stimulus with an unconditioned stimulus to create a conditioned stimulus (e.g., dog salivating when hearing a bell).
