Lesson 20: ACT Science Mastery

Passage

A biology instructor is teaching a lesson on oceanic shrimp. Some oceanic shrimp are vertical migrators. Most populations of vertically migrating shrimp are found at the bottom of their depth range during the day and then move to the top of their depth range at night. 

The biology teacher presented her students with a chart (Table 1) showing the depth ranges and water, protein, carbohydrate, and lipid con tent of three vertically migrating (vm) species of shrimp along with three non-migrating (nm) species for comparison purposes.

Multiple Choice

Based on the information contained in Table 1, vertically migrating shrimp have a higher percentage content of :

• lipid and carbohydrate

• water and lipid

• water and protein

• lipid and protein

Multiple Choice

Based on the information contained in Table 1, non-migrating shrimp have a higher percentage con tent of :

• lipid

• water

• protein

• carbohydrate

Multiple Choice

Assuming that the species described in Table 1 are representative of all shrimp types, if a new shrimp species were discovered with a protein content of 62%, it is most likely that the shrimp species:

• is a vertical migrator

• is a non-migrator.

• has a higher lipid percentage than vertical migrators.

• has a 10% carbohydrate content

Multiple Choice

If a higher lipid percentage helps the shrimp with stand cold temperatures, which shrimp species is most likely to survive a localized climate shift that drop temperatures several degrees?

• vm B

• vm C

• nm B

• nm C

Multiple Choice

If a higher lipid percentage helps the shrimp with stand cold temperatures, which shrimp species is least likely to survive a localized climate shift that drops temperatures several degrees?

• vm B

• vm C

• nm B

• nm C

Multiple Choice

A shrimping boat has a net that only reaches 50 meters deep. If the six shrimp species in Table I are the dominant species of shrimp in the area, what would be the best time for this boat to go shrimping and make a successful catch?

• Noon

• Afternoon

• Night

• The timing does not matter.

Multiple Choice

Based on the information contained in Table 1, non-migrating shrimp have a higher percentage con tent of :

• lipid

• water

• protein

• carbohydrate
