Some fish have a bacterium named Edwardsiella tarda growing in them. Edwardsiella tarda can kill fish by infecting their blood, which normally has a neutral pH. Ceviche is a dish that often uses fish as one of the ingredients. To prepare ceviche, the fish, along with other ingredients, is soaked in lemon juice, which has a pH around 2.5. The fish is not cooked using heat. If the fish used in ceviche are contaminated with the organism Edwardsiella tarda, you might be afraid of getting sick from eating ceviche. However, the addition of lemon juice will prevent anyone from getting ill from consuming Edwardsiella tarda. Based on your understanding of the function of enzymes, explain why the use of lemon juice in ceviche will prevent Edwardsiella tarda from causing an infection.

Scientists are interested in investigating how limestone can be used to remediate the effects of acid rain. They collect water from a lake that has recently been exposed to acid rain. They divide the water into 10 different tanks and add different amounts of limestone to nine of the tanks. No limestone is added to one of the tanks. The pH of the water in the tanks is measured before the limestone is added and once every hour for 24 hours. (f) Identify the independent variable in this investigation. (g) Identify the dependent variable in this investigation. (h) Identify the control group in this investigation. (i) Describe one additional variable that has not been mentioned that could affect the results of the investigation. (G) Describe a modification that could be made to the investigation that would affect the results.

What features of ionizing radiation make it a good choice for killing microbes in packaged materials?  Ionizing radiation is safe for killing microbes on living surfaces (such as human tissues). Ionizing radiation does not require special instruments or equipment. Ionizing radiation kills endospores. Ionizing radiation is able to penetrate the packaging materials.
