Mr. Vannoy Trivia
100
Define diffusion.
The random movement of particles from high concentration to low concentration
100
What is exocytosis?
When molecules are actively transported out of the cell.
100
Where does water flow if a cell is placed in a hypotonic solution?
Into the cell.
100
When a potato is put into salt water what happens to the potato?
The potato shrinks
100
What color are Mr. Vannoy's shoes?
Brown
200
Give one real world example of diffusion.
Various answers that have to describe particles moving from high concentration to low concentration.
200
What is phagocytosis?
When solid material is actively transported across a membrane in either direction.
200
Where is the highest concentration of water when a cell is placed into a hypertonic solution?
Inside the cell
200
Why did we use tap water with 1% salt instead of distilled water with 0% salt?
Human fluid (blood, plasma, saline) has 1% salt.
200
Where does Mr. Vannoy go to the gym?
No where
300
What is the main difference between osmosis and diffusion?
Osmosis is water moving and diffusion is anything moving.
300
Describe the types of active transport used when a White Blood Cell attacks bacteria in the blood stream.
Endocytosis and Phagocytosis
300
When water flows into the cell and then flows back out what kind of solution is the cell in?
Isotonic
300
Why do potatoes shrink in salt water?
The water leaves the potato's cells.
300
Name one country Mr. Vannoy been to not on this continent.
Germany, France, United Arab Emirates
400
How can large particles get to the other side of a cell membrane if they cannot diffuse through the membrane?
Protein channels allow large and/or charged particles to cross the membrane without going through the membrane.
400
What vocabulary word does active transport not support? (Hint: it starts with an H)
Homeostasis
400
What kind of solution was the gummy bear put into the first day? Use vocabulary.
Hypotonic
400
List the independent variable, the dependent variable, and the control for the potato lab.
IV: Amount of Salt DV: Mass of potato Control: Tap water
400
What is Mr. Vannoy's favorite professional sports team?
Arizona Coyotes
500
When solute concentration is the same on both sides of a membrane, where does the water move?
Both into and out of the cell.
500
Give one example of why active transport is needed.
To move particles from low concentration to high concentration.
500
Why don't doctors use pure water to hydrate patients that are dehydrated?
Pure water has too high of a concentration of water and it will rush into the cells and cause them to burst and die.
500
When you drink salt water what happens to your cells?
They shrink
500
What event did Mr. Vannoy score points in at the state track meet in 2010?
110m hurdles
