Researchers wanted to proof that men who ate fried chicken for
more than 6 years straight doubled the risk of getting high
cholesterol, so they started a cohort study. In 2006, 1,000 men
were enrolled in the study and they did not have cholesterol. In
2017, 70% were free of high cholesterol. 1.5% of the cholesterol
free men ate fried chicken for about 6 years. The 200 men that ate
it for over 6 years developed high cholesterol years after...

4) In 2011, researchers discovered bacterial cells possessing
human genes, they found that more than 10% of a Neisseria
gonorrhoeae population, the species responsible for gonorrhea,
contained a human DNA fragment. This fragment was not found in
other species of Neisseria. How might a bacterial cell
have acquired human DNA? Explain

A car washing and lubricating company has been operating for
more than 10 years in a terrain with the following characteristics:
porous, filterable with a freatic level near to the surface (5 m
depth). This area is close to the estuary which is very useful to
them since all the disposals and waste generated by this activity
are directly released into the estuary. These disposals contain a
high level of oils and greases. All the dumping from the car

QUESTION 1:
Researchers claim that women speak significantly more words per
day than men. One estimate is that a woman uses about 20,000 words
per day while a man uses about 7,000. To investigate such claims,
one study used a special device to record the conversations of male
and female university students over a four- day period. From these
recordings, the daily word count of the 20 men in the study was
determined. Here are their daily word counts:
