What is the main role of the nonspecific defense?
It is the first line of defense against pathogens.
It is the last line of defense against pathogens.
It is only supposed to kill pathogens that are not a serious problem.
It is only supposed to kill pathogens only after they are found or that are not killed by the specific defense.
Based on the graph, which conclusion about the impact of MRSA on human health is best supported?
Methicillin will be less effective when used on patients.
In the 1980's, doctors began prescribing more antibiotics which decreased cases of MRSA.
Better treatment options were discovered in 1990 that led to fewer cases of MRSA in the future.
MRSA will evolve into a virus and become more susceptible to antibiotics.
Based on the graph, which of the following correctly describes the impact of the Lynch mutation on an individual's health?
The Lynch mutation has the largest risk difference on a person's chance of being diagnosed with ovarian cancer.
The Lynch mutation has the largest risk difference on a person's chance of being diagnosed with colorectal cancer.
The Lynch mutation has the smallest risk difference on a person's chance of being diagnosed with cancer a second time within 15 years of initial diagnosis.
The Lynch mutation has the smallest risk difference on a person's chance of being diagnosed with endometrial cancer.
Based on the graph, which of the following best explains the difference in response to antigen A and antigen B?
Antigen B response was greater because antibodies were fighting antigen A.
Antigen B response was greater because a vaccine was given to fight antigen A.
Antigen A response was greater because there were memory cells to fight only antigen A.
Antigen A response was greater because there were no memory cells.
Your mom gave you antibiotics because you had symptoms that were similar to the flu. Which of the following best explains if your mom was correct or incorrect for giving you the antibiotics?
She is incorrect because the flu is a viral infection and antibiotics do not work on viruses.
She is correct because antibiotics can cure all and will kill the virus.
She is incorrect because the antibiotics she gave you were not prescribed for bacterial infections.
Which of the following types of white blood cells are part of your nonspecific defense?
Macrophage
Killer T Cell
Helper T Cell
B Cell
Lyme disease is spread by ticks and can cause fever, skin rash, and joint pain. Climate change has increased the population of the ticks that spread Lyme disease. Which of the following best describes the public health impact from environmental changes?
Diseases that are spread by animals will be less common because their environments are being destroyed.
A disease that was originally contained will now spread to more people.
Climate change decreases the impact of diseases.
Environmental changes have no impact on public health.
How does looking at comparative anatomy (comparing the skeletons/bones of two different animals) support the theory of evolution?
It doesn't support the theory of evolution.
It gives evidence for common ancestry.
It shows that animals were the same size and lived in the same environments.
Organism 1 is a bat, organism 2 is a whale, and organism 3 is a sea lion. All three are mammals with similar forelimbs. Based on the table, which of the following statements best describe the comparative anatomy between the organisms?
Organisms 2 and 3 share vestigial structures.
Organisms 2 and 3 share analogous structures.
Organisms 1 and 2 share homologous structures.
Scientists were studying frogs on an island. Most of them had feet without webbing and brown spots, and were more adapted to live on land. A small number of the frogs did have webbed feet and no spots, and were more adapted to live in water. Over the years, due to climate change, there was constant flooding on the island, which means there was less land. What would happen to how the frogs will look over time?
There will be less frogs with webbed feet.
There will be more frogs with webbed feet.
The frog population will decrease but still look the same.
The frogs would mutate into fish.
There is a bird on the Galapagos that usually eat small, soft seeds because their beaks are adapted for those seeds. A drought caused a big decrease in the number of the small, soft seeds and left only large, tough seeds. 78% of the bird population died off because most could not eat the large, tough seeds. A few years later, the average beak size of the bird was larger than before the drought. Which of the following best explains the increase in beak size?
The birds grew bigger beaks because of no water.
The birds with smaller beaks grew bigger beaks because they wanted to.
The birds with bigger beaks could survive and reproduce to pass that trait down.
