Multiple Choice

A student wanted to compare the transpiration rates of two different plant species at varying levels of humidity. The results are recorded in the table shown. Each plant group was given the same amount of water and light throughout the investigation. Which procedure should have been performed to prevent error in this investigation? (49.2%)

• The percentage of humidity should have been kept constant.

• Fewer plants should have been included in each group.

• One type of plant should have been tested.

• Both groups should have been tested in the same soil type at each humidity level.

Why is nitrogen important to life?

• Plants and animals could not live without nitrogen. It is an important part of many cells and processes such as amino acids, proteins, and even our DNA. It is also needed to make chlorophyll in plants, which plants use in photosynthesis to make their food and energy.

Multiple Choice

(63.9%)

• a decrease in the number of fossils formed in the soil

• increased water pollution in the soil

• a reduction in the amount of nitrogen available to the ecosystem

• increased precipitation and flooding of the soil

Multiple Choice

(57.4%)

• identifying new diseases spread by pets

• altering the chromosomes of healthy pets

• making more treatments available for pets

• decreasing the number of antibodies produced by pets

After 24 hours, the amount of gas that accumulated at the top of the inverted test tube is measured.
