ACT Science Practice Test 1

According to the results of Study 1, which stimuli proved to be most effective in attracting the cockroaches?

• Lemon Oil

• 5% acetic acid

• 35% ethanol

• Cannot be determined from the given information.

Based on Table 3, as the concentration of acetic acid increased, the time to reach the medium:

• increased only

• decreased only

• remained constant

• varied, but with no general trend

A researcher wanted to reproduce a study that yielded the slowest time to reach the medium. According to the results of Studies 1 and 2, the researcher would construct a study containing:

• Normal cockroaches and a lemon oil stimulus

• abnormal cockroaches and a lemon oil stimulus

• normal cockroaches and a 5% acetic acid stimulus

• abnormal cockroaches and a 5% acetic acid stimulus

Suppose an additional trial in Study 3 had been performed using a 7% acetic acid stimulus. According to Table 3, the time for the normal cockroaches to reach the medium would most likely have been:

• less than 15 seconds

• between 15 and 27 seconds

• between 27 and 48 seconds

• greater than 48 seconds

Based on Table 2, how many minutes, on average, did it take the cockroaches to reach the medium when exposed to lemon oil?

• 0.25 minutes

• 0.50 minutes

• 0.75 minutes

• 1.00 minutes

Suppose an additional trial in Study 1 had been performed using 40% ethanol stimulus. Assume changing the concentration of ethanol yields the same effect as changing the concentration of of acetic acid. Based on Studies 1 and 3, the time for the normal cockroaches to reach the medium would most likely have been :

• less than 15 seconds

• between 15 and 16.5 seconds

• between 16.5 and 18 seconds

• greater than 18 seconds

Suppose Study 3 had been repeated using abnormal cockroaches instead of normal cockroaches. Based on the results of Studies 1 and 2, how would this change the results of Study 3? The time for the cockroaches to reach the sugar medium would:

• decrease for all stimuli tested

• increase for all stimuli tested

• both decrease and increase depending on the stimuli tested

• not change for any stimuli tested

According to Figure 1, at 1 atm, as temperature increases, the density of water:

• increases only

• decreases only

• increases, then decreases

• decreases, then increases

According to Figure 2, at 1 atm, as temperature increases, the absolute pressure if water:

• increases only

• decreases only

• increases, then decreases

• decreases, then increases

According to Figure 3, at 1 atm, as temperature increases, the specific entropy of water:

• increases only

• decreases only

• increases, then decreases

• decreases, then increases
