HSA Questions

A student wants to perform an investigation to determine the respiration rate of a runner.  A classmate on the cross-country team tells her the respiration rate should be about 20 beats per minute. How could this information affect the investigation?

• it could reduce the number of measurements needed
• it could increase the accuracy of the data
• it could remove experimental error
• it could introduce bias

Which of these supply the main energy source used in cellular respiration?

• sugars
• fats
• protein
• DNA

Use the information below to answer the following question. Scientists have recently discovered a new species that lives attached to the side of a tree.  An organism from this new species ·  is multicellular ·  has cell walls ·  has vascular tissues ·  makes its own food  ·  has structures that absorb moisture from the air   The scientists put the organism in a sealed glass container and placed it in the dark overnight.  Which of these increased inside the container?

• carbon dioxide
• oxygen gas
• nitrogen gas
• water

Use the information and the graph below to answer the following question. Scientists wanted to study the effect of water temperature on the swimming speed of goldfish.  They set up an experiment in which they raised populations of goldfish in two different aquariums. Population 1 was raised at 5^oC.  Population 2 was raised at 25^oC.  All other variables were constant in both aquariums.  The results of this experiment are shown in the graph below.   If the temperature of the water decreased from 25⁰C to 20^oC, the goldfish in Population 2 would most likely

• excrete more salt
• produce less carbon dioxide
• use more glucose
• use more oxygen

According to the graph both populations of goldfish swim at the same speed at which of these temperatures?

• 12^oC
• 17^oC
• 22^oC
• 27^oC

Which of these is not recycled through Earth’s ecosystems?

• carbon
• energy
• water
• oxygen

Students in a biology class studied the effects of temperature on the production of carbon dioxide by yeast cells. They designed an investigation using materials similar to those shown below. They counted the number of carbon dioxide bubbles produced by the yeast at different temperatures. The graph below shows the results. Which of these corresponds to the amount of carbon dioxide that would most likely be produced at 30^oC?

• 20 bubbles per minute
• 40 bubbles per minute
• 60 bubbles per minute
• 80 bubbles per minute
