Science Data

Based on this graph, which of the following statements is true?

• the anole weighs 2.5 grams after 3 days of observation
• the mass of the anole increased by 2.5 grams in 3 days
• the anole weighs 2.3 grams after 3 days
• the mass of the anole increased by 2.7 grams during the experiment

A scientist performs an experiment to see if acids have an effect on the health of a particular type of plant. Three sets of plants were treated with acidic solutions of known pH while the control set was treated with a solution of neutral pH 
Which is the best conclusion for this experiment? 

• Acid has no effect on the health of this type of plant
•  High acidity is helpful to this type of plant.
• Low acidity is harmful to this type of plant.
• High acidity is harmful to this type of plant.

Which row in the chart below indicates the correct process for each event indicated? 

• row one
• row two
• row three
• row four

_{Which statement is a correct conclusion to the shown graph?}

• The reaction occurred FASTER with the enzyme
• The reaction occurred SLOWER with the enzyme
• Energy is absorbed and stored
• Energy absorbed increases, then decreases

Which of the following conclusions can be drawn from this graph?

• The optimum pH of the enzyme is 6.6.
  
• The optimum pH of the enzyme is 5.8
  
• The enzyme’s activity increases as pH increases 5.0 to 9.0
  
• The enzyme’s activity is greater around pH of 8.0 .
  

Which of the following graphs best illustrates the relationship between the heat released by the foods listed in Table 1 and the change in water temperature?

• A
• B
• C
• D

Based on the graph shown on tomato height, what limiting factors may have contributed to the height growth of Plant C compared to Plant's A & B?

• temperature, amount of water, nutrient levels, light exposure
• lack of copper and zinc in soil
• excessive light exposure and amount of water
• none of the above

What conclusions can you draw in regards to the amount of light a plant was exposed to and how tall the plant grew?

• 4 hours of light exposure resulted in greatest height growth increase
• 8 hours of light exposure resulted in greatest height growth increase
• 16 hours of light exposure resulted in greatest height growth increase
• 16 hours of light exposure in conjunction with 1 cup of water resulted in greatest height growth increase

What conclusions can you draw in regards to the amount of water given to a plant and how tall the plant grew?

• 1 cup of water results in greater height growth than 1/4 cup of water
• 1 cup of water combined with light exposure has the greatest increase in height growth
• water isn't necessary for plant height growth
• water is all that is needed for plant height growth

In general, the results of Study 1 suggest that peony seeds that are placed in a petri dish containing damp paper are most likely to germinate when they are maintained at which of the following temperatures?

• 13 degrees
• 18 degrees
• 23 degrees
• 28 degrees
