The human genome project
a. was completed in 2003
b. is still underway and may be completed in the next decade
c. provides information that will allow people to genetically alter their appearance
d. was a good idea, but couldn't be put into practice
*this is for edgenuity*

The correct answer is:  
a. was completed in 2003

it was started in 1990, and run until 2003 (so we know that the first answer is correct and the second isn't). it provided a big amount of important information, but it' didn't allow anyone to alter their appearance, as this is not something that can be achieved via genetics.   

Air goes past the epiglottis and into the trachea when you breathe in. from there, it goes to your vocal cords in the larynx until it reaches the bronchi. from the bronchi, air passes into each lung.
