What evidence from graph 1 suggest that there will some live bacteria in milk on day 5?
Graph 1 likely shows a trend of bacterial growth over several days, indicating an increase in bacterial counts. If the data points for days 1 through 4 demonstrate a consistent rise, it suggests that conditions in the milk are conducive to bacterial survival and reproduction. Therefore, based on the observed growth pattern, it can be inferred that some live bacteria will still be present in the milk on day 5.

What do galactosemia and tay-sachs disease have in common?
Both galactosemia and Tay-Sachs disease are genetic disorders caused by the absence or dysfunction of a particular enzyme. Galactosemia is a disorder where the body is unable to break down galactose, a sugar found in milk, while Tay-Sachs disease is a disorder where the body lacks an enzyme needed to break down certain lipids in the brain. Both conditions can lead to serious health complications if not managed properly.
