Give a real-life example of Pavlov's Theory of Classical Conditioning.
Every day for 6 months, before my friend drove me home from softball practice, I would wait for her to unlock the car door since the car does not have automatic locks. I became conditioned to wait to get the reward of sitting in the car and getting a ride home. One day, when my friend switched to a car that automatic locks, I still stood outside of the car waiting for her to unlock the door, even though it was already unlocked. I had been classically conditioned to wait for an unlocked door when I did not need to.
Cellular movement using microtubules is often linear, rapid, and targeted. Explain why the process of diffusion does not apply to this type of movement. What are the basic needs for a cell to have this type of linear, rapid, targeted movement?
The process of diffusion is slow and occurs when a substance travels from a high concentration to a low concentration through some sort of membrane. Cells that have a linear, rapid and targeted movement need some sort of microtubule track, such as microfilaments. They also need a chemical signal from the target, possibly a bacteria invader, and need mechanical energy in the form of ATP.
Sally has $8.40. Emily has twice as much money as Sally. If Jennie has 5 times the amount of money as Emily, how much money does Jennie have?
First, determine the amount of money that Emily has by doubling the amount of money Sally owns. 8.40*2=16.80. Next, determine the amount of money Jennie has by multiplying Emily's known amount by five. 16.80*5=84.00. Jennie has $84.00
