An infected individual hugs an uninfected individual, depositing the pathogen on the new person. This form of disease transmission is an example of:

• Direct Contact

• Indirect Contact

• Droplet Transmission

• Vector Transmission

An infected individual pays at the grocery store with infected cash, spreading the pathogen to the cashier. This form of disease transmission is an example of:

• Direct Contact

• Indirect Contact

• Droplet Transmission

• Vector Transmission

An infected individual coughs into the air, then an uninfected individual inhales the particles, acquiring the pathogen. This form of disease transmission is an example of:

• Direct Contact

• Indirect Contact

What does Y represent on the diagram above?

• deoxyribose sugar

• phosphate

• A-T base pair

• C-G base pair

Determine the dependent variable:  Researchers select 10 healthy 40 year old men and have them sit calmly in the same relaxing environment for 2 hours.  Then, the researchers take their blood pressure using a standard blood pressure cuff.  Next, the researchers have the same 10 people do 50 jumping jacks and measure their blood pressure again.  What is the dependent variable?

• the exercise -  50 jumping  jacks

• resting prior to the experiment

• the blood pressure

• 10 people 

Identify what structure is outlined in the BLACK outline.

• Base pair

• deoxyribose sugar

• phosphate group

• hydrogen bonds

• Nucleotide
