One of the causes for antibiotic resistance is:
Taking any antibiotics
Taking antibiotics for bacterial infections
Evolutionary adaptation
Taking antibiotics for viral infections
Why do some bacteria survive antibiotics that are supposed to kill them?
They have more experience over other bacteria
Random gene mutations
They are red instead of yellow
They are similar to wolves and hold other bacteria in check
True or false: Any use of antibiotics causes multi-drug resistance
True
False
Which of these is NOT an incorrect use of an antibiotic?
Using all of my prescribed antibiotics for my bacterial infection
Using my friends antibiotics for my bacterial infection
Using only half of my prescribed antibiotics because I felt better
Using antibiotics for my viral infection
Bacteria that is easily killed off by antibiotics:
Weak Bacteria
Resistant Bacteria
Sensitive Bacteria
Vulnerable Bacteria
In the elk and wolf analogy, the elk were:
Held in check by the wolves.
On top of the wolves.
Holding the wolves in check.
Eating other harmful microbes.
Which of the following has the highest usage of antibiotics?
Crops
Pets
Humans
Livestock
Drug companies are not developing as many new antibiotics anymore because:
The market is saturated
They have already developed all possible antibiotics
They are the cause of multi-drug resistant bacteria
It does not make them as much money
Your gut flora is not very healthy right now because you overused antibiotics. You start eating yogurts and probiotics. How would this help?
They release enzymes that aid in digestion
They kill off the bad bacteria taking over your gut
They serve as a laxative to clear out your gut
They destroy toxins that were released by bad bacteria
The difference between observational and experimental studies:
Observational studies have a control, experimental do not.
They are the same, just different names.
Experimental studies have a control, observational do not.
Observational studies have variables that are manipulated, experimental do not.
Mimicry is a helpful evolutionary trait for the king snake,
Only where brown snakes are present
Only where coral snakes are present
Everywhere it lives
Only where it can use its skin for camouflage.
Which of these graphs shows the results for the area where ONLY king snakes live?
Left
Right
Select the statement that does NOT apply to the Wakefield autism and vaccines study:
The sample size was too small
The study was retracted in 2010
The study did not have a random sample of subjects.
The study was the direct cause of a decline in MMR vaccinations
Which of these is NOT true surrounding what we know about autism?
There is a link between autism and parents' age, pollution, mom's nutrition
There are many genes related to autism
Autism is a result of only environmental factors
The cause of autism has to do with and speech and language processing
When an atom has high electronegativity, it means:
The atom is the bunny in our monster-bunny analogy
The atom has a low atomic number
The atom has very few electrons
The atom is greedy
What is true about the periodic table:
As you go right, the electronegativity of each element decreases
As you go right, the electronegativity of each element increases
As you go left, the electronegativity of each element increases
As you go down, the electronegativity of each element increases
In a class exercise Dr. B represented an electron, and the students represented protons. What was the purpose of this exercise?
To show that atoms with higher atomic numbers have equal electronegativity to atoms with lower atomic numbers
To show that atoms with higher atomic numbers have a weaker electronegativity
To show that atoms with lower atomic numbers have a higher electronegativity
To show that atoms with higher atomic numbers have a higher electronegativity
In the O Monster and H bunny analogy,
The H bunny was the favorite in the tug-of-war
The H bunny was the loser in the tug-of-war
The O monster was the favorite in the tug-of-war
The O monster was the winner in the tug-of-war
In H2O, hydrogen and oxygen are bonded via:
Hydrogen bonds
Covalent polar bonds
Ionic bonds
Covalent nonpolar bonds
Which of the following is FALSE about why H2O is polar?
There is a large difference in electronegativity btwn. H and O
O is partially negative and H is partially positive
The shared electrons are closer to O than to H
H donated an electron to O, causing a H+ ion and a O- ion
Hydrogen bonds occur:
Between H2O molecules
Within H2O molecules
Similar to a tug-of-war with a winner
When the O-monster is greedier and stronger than the H-bunnies
Ionic bonds are when electrons on the outer shell are

Shared
Donated and received
Already full
None of the above
Atoms in ionic bonds have:
A very large difference in electronegativity
Similar electronegativity
A large difference in electronegativity
Hydrogen bonds are due to:
