<span>The inferences I can make regarding the pH of a particular part of the digestive system is that it has a pH of 3. I know that 7 is neutral, and 8-14 is basic. I know that below 7 is acidic. The lower the number is from 7, the more acidic it is. I know that hydrochloric acid is quite acidic because I feel the burn from it when I get acid reflux attacks.
I think the relative size of carbon-based molecules are the size of a nickel, which I think is quite large. I think this because humans need carbon to live and a lot of foods contain carbon, so a lot of carbon molecules are broken down in the digestive tract.</span>

ANSWER: Trapped in a ship's ballast or water tank.
REASONING: There are many examples of species being transported in the ballast or water tank of ships. Ships need to be stable so they don't turn over. Stability is provided by weight in the bottom part of the ship called the ballast. This weight often comes from water that is stored in water tanks or the ballast area of the ship. Water is taken in to the ballast at the beginning of its voyage. When it arrives at it's destination, the ballast water is often drained. Anything living in that water will also be drained in to the new location. This is how species like the white perch can be introduced into new areas.
