- Based on Figure 1, at which labeled location does vapor first cool enough to return to the liquid state?
Answer: Location 3
Location 3 marks the sloping tube surrounded by the cold water jacket, the only part of the apparatus in Figure 1 that is actively cooled, so vapor condenses there. Location 1 is the heated flask and Location 2 is the thermometer above it, both of which the vapor passes while still hot. Location 4 is the receiving flask, which the liquid reaches only after condensing.
- Based on Figure 1, bile from the liver and enzymes from the pancreas are both released into which organ?
Answer: Small intestine
Figure 1 shows the bile arrow from the liver and the enzyme arrow from the pancreas both ending at the small intestine. Neither arrow points to the esophagus, the stomach, or the large intestine; those parts of the tract are connected only by the arrows tracing the path of food.
- According to Figure 1, which two processes move water into the water vapor reservoir?
Answer: Evaporation and transpiration
Two arrows in Figure 1 point toward the water vapor reservoir: evaporation from the ocean and transpiration from plants. The condensation arrow points away from water vapor toward clouds, and infiltration and runoff both move water away from the land surface without reaching the vapor reservoir.
- According to Figure 1, which well does not extend below the water table?
Answer: Well 2
The water table in Figure 1 deepens from left to right, from 6 m below the surface at the left edge to 14 m at the right edge. Well 2 is drilled to 8 m at a point where the water table lies at about 9 m, so its bottom sits above the saturated zone. Wells 1, 3, and 4 all end below the water table line at their positions and would yield water.
- A student uses a calorimeter to measure heat released by dissolving a salt in water. Figure 1 shows the calorimeter cup, lid, thermometer, and stirrer, including which parts contact the solution. According to Figure 1, which component is inserted through the lid and extends into the solution to measure temperature?
Answer: The thermometer probe
The calorimeter diagram shows a cross-sectional view with the lid on top and various components passing through it. The thermometer probe is clearly shown as a long, thin instrument that passes through a hole in the lid and extends down into the solution inside the calorimeter cup. This positioning allows it to measure the temperature of the solution directly. The stirrer rod also passes through the lid but serves a different function of mixing the solution.
- Based on Figure 1, which bulbs remain lit once switch S is opened?
Answer: Bulbs 1 and 3
Figure 1 shows switch S in the branch containing Bulb 2 only. Opening S breaks that branch, so Bulb 2 goes out. Bulbs 1 and 3 sit in separate branches that still connect to both battery terminals, so both stay lit.
- Based on Figure 1, a nitrogen atom moving from atmospheric nitrogen gas into plant protein passes through which sequence of soil reservoirs?
Answer: Ammonium, then nitrite, then nitrate
Following the arrows in Figure 1 from atmospheric nitrogen gas: nitrogen fixation leads to ammonium, step 1 leads from ammonium to nitrite, step 2 leads from nitrite to nitrate, and assimilation leads from nitrate into plant protein. The order is ammonium, nitrite, nitrate. The option beginning with nitrate reverses that order, and no arrow connects ammonium directly to nitrate.
- A biologist traces airflow through a simplified human respiratory system diagram (Figure 1). Arrows indicate the direction of airflow during inhalation. Based on Figure 1, air flows from the trachea directly into the:
Answer: Bronchi
The respiratory system diagram shows the trachea as the main airway that branches into two tubes labeled as bronchi. Arrows indicating airflow during inhalation show air moving down the trachea and then splitting into the left and right bronchi at the branching point. The bronchi then continue to branch into smaller airways leading to the alveoli. The diagram clearly shows this direct connection between trachea and bronchi without any intervening structures.
- Based on Figure 1, which organism serves as a direct food source for both the snake and the hawk?
Answer: Mouse
Two arrows leave the mouse in Figure 1: one to the snake and one to the hawk, so the mouse is eaten by both. The grasshopper's only outgoing arrow goes to the snake, and the rabbit's only outgoing arrow goes to the hawk. Grass is eaten by the grasshopper, mouse, and rabbit, but by neither the snake nor the hawk.
- Based on Figure 1, which labeled point is the epicenter of the earthquake?
Answer: Point J
The epicenter must lie on all three circles at once, which happens only where the three circles intersect. In Figure 1 that single common point is Point J. Each of Points K, L, and M lies clearly inside or outside at least one of the three circles, so none of them can be on all three at once.
- According to Figure 1, which labeled arrow represents the normal force on the block?
Answer: Force 1
Force 1 is the only arrow in Figure 1 drawn at a right angle to the inclined surface and pointing away from it, which is the definition of the normal force given in the passage. Force 2 points straight down, the direction of the block's weight. Forces 3 and 4 lie along the surface rather than perpendicular to it.
- Based on Figure 1, at which site would the wind be fastest?
Answer: Site K
The isobars in Figure 1 are spaced most closely near Site K, so pressure changes over the shortest horizontal distance there and the wind is fastest. Sites J, L, and M all sit where neighbouring isobars are farther apart, indicating slower wind.
- According to Figure 1, how far has the rock on the right side of the fault moved down relative to the rock on the left side?
Answer: 4 m
Track any single layer boundary across the fault. The top of Layer L sits at 5 m on the left side and at 9 m on the right side, a drop of 4 m; the top of Layer M sits at 11 m on the left and 15 m on the right, the same 4 m drop. The 6 m option is the thickness of Layer L rather than the offset.
- According to Figure 1, blood leaving the lungs flows into which structure next?
Answer: Left atrium
The arrow leaving the lungs in Figure 1 points to the left atrium. From there a separate arrow carries blood to the left ventricle and then to the body tissues, so those structures are reached later. The right atrium receives blood returning from the body tissues, before the lungs rather than after.
- A student investigates how water flows through a filtration apparatus. Figure 1 shows the setup, including tubing connections and the direction of flow (arrows). The student wants to collect the filtered water that exits the filter. According to Figure 1, which container should receive the filtered water?
Answer: Beaker B (downstream of the filter, after the outlet tube)
Figure 1 shows a filtration apparatus with flow direction indicated by arrows, where water moves through the filter and exits via an outlet tube. The diagram clearly shows Beaker B positioned downstream of the filter, directly beneath the outlet tube where filtered water would exit. The arrows indicate water flows from the inlet through the filter and out the outlet tube into Beaker B. Beaker A is positioned upstream before the filter, so it would contain unfiltered water rather than the filtered product.
- Based on Figure 1, pushing down at which position requires the smallest effort force to balance the load?
Answer: Position S
Balancing requires effort × distance = 200 N × 0.4 m = 80 N·m. The larger the distance from the fulcrum, the smaller the force needed. Position S is the farthest at 1.6 m, requiring 80 ÷ 1.6 = 50 N. Position P at 0.4 m would require 200 N, Position Q 100 N, and Position R about 67 N.
- Based on Figure 1, at which labeled point is the ground steepest?
Answer: Point X
Steepness corresponds to how closely the contour lines are spaced. In Figure 1 the lines are packed most tightly around Point X, so elevation changes fastest there. Point W sits near the top of the hill, where the contours are widely spaced, and Points Y and Z lie on the outer flank, where the spacing is wider than at Point X.
- According to Figure 1, the image forms at what distance from the lens?
Answer: 8 cm
The two rays drawn in Figure 1 cross at the 8 cm mark on the right side of the lens, so the image forms 8 cm from the lens. The 4 cm mark is the focal point F, not the image position, and the object itself sits 8 cm to the left of the lens.
- According to Figure 1, what is the thickness of Layer III?
Answer: 6 m
Figure 1 places the top of Layer III at a depth of 9 m and its base at a depth of 15 m. The thickness is the difference between those depths: 15 m − 9 m = 6 m. The 4 m option is the thickness of Layer V, the 5 m option is the thickness of Layer IV, and the 9 m option is the depth of the top of Layer III rather than a thickness.
- According to Figure 1, which structure lies immediately inside the cell wall?
Answer: Cell membrane
In Figure 1 the cell wall is the outermost boundary, and the cell membrane is drawn directly against its inner surface. The central vacuole, the nucleus, and the chloroplasts all sit farther in, within the cytoplasm enclosed by the membrane.
