Bio SOL Review - Scientific Investigation Shorter

An important feature of modern classification system is that they

• group organisms that live in the same habitat
• apply only to organisms that are alive today
• can predict the discovery of new species
• can incorporate new scientific discoveries

Henry's project is on porcupine populations in Virginia.  He would like to use the phone book to help him make contacts.  His most reliable contacts would probably be found in the phone book under -

• state agencies
• newspapers
• travel agencies

• civil engineers

In 1928, the scientist Alexander Fleming was trying to grow the bacterium Staphylococcus, and by chance, discovered that it would not grow in the presence of a mold that he named Penicillium. In 1939, Ernst Chain and Howard Florey purified penicillin, and in 1941, penicillin was first used to treat bacterial diseases. In 1945, Alexander Fleming, Ernst Chain, and Howard Florey received the Nobel Prize in medicine for the discovery and isolation of penicillin. These facts show that — 

• Florey and Chain unfairly used Fleming’s work and should not have received the Nobel Prize
• whenever possible, the Nobel Prize should be given to more than one person
• scientific progress often requires the efforts of many people working together
• chance plays no role in scientific discoveries

What is the total magnification used to view these onion cells through this microscope setup? 

• 50 X
• 400 X
• 40 X
• 10 X

The picture shows a coverslip correctly being lowered onto a slide. This method is used because it — 

• prevents the escape of microorganisms found in the water
• reduces the possibility of air bubbles on the slide
• prevents the coverslip from moving
• allows microorganisms to move freely in the water

A scientist designed an experiment to test the effect of temperature on bacterial growth. He grew three different cultures of the bacterium E. coli under three heat lamps at different temperatures. What was the independent variable in this experiment?

• length of experiment
• number of bacteria
• Reproduction rate
• Temperature
