Question

the location of 105 fish, shellfish, and other marine species in the eastern bering sea and along the u.s. northeast coast was determined by tracking the location of each species from 1982 to 2015. both latitude and depth were followed and expressed as the average center of biomass (central location for each population by weight) and shown in the graphs. change in latitude and depth of marine species, 1982-2015 latitude graph: y-axis “average distance moved (miles)”, x-axis “year (1980–2020)”; depth graph: y-axis “average change in depth (feet)”, x-axis “year (1980–2020)” how much farther north were these species found in 2015 compared to 1982?
○ 22 miles
○ 25 miles
○ 5 miles
○ 10 miles
how much deeper were these species in 2015 compared to 1982?
○ 45 feet
○ 22 feet
○ 10 feet
○ 30 feet

Explanation:

First Sub - Question (How much farther north were these species found in 2015 compared to 1982?)

Step1: Analyze the latitude graph

In the latitude graph, at 1982 (the start year, around 1980 - 1982), the average distance moved (north - south) starts near 0. In 2015, the value on the latitude graph (average distance moved north) is around 22 miles (by observing the y - axis of the latitude graph, the value in 2015 is approximately 22 miles more northward than in 1982).

Step2: Evaluate the options

The options are 22 miles, 25 miles, 5 miles, 10 miles. From the graph, the difference in northward movement from 1982 to 2015 is approximately 22 miles.

Second Sub - Question (How much deeper were these species in 2015 compared to 1982?)

Step1: Analyze the depth graph

In the depth graph, at 1982 (around 1980 - 1982), the average change in depth starts near 0 (shallow). In 2015, the value on the depth graph (average change in depth, deeper is positive in terms of the change) is around 45 feet? Wait, no. Wait, the y - axis for depth is "Average change in depth (feet)", with 0 at the top (shallow) and 50 at the bottom (deep). In 1982, the depth change is near 0 (shallow), in 2015, the depth change is around 45 feet? Wait, no, let's re - check. Wait, the graph for depth: in 1982, the value is near 0 (shallow), in 2015, the value is around 45 feet? Wait, no, the options are 45 feet, 22 feet, 10 feet, 30 feet. Wait, maybe I misread. Wait, the depth graph: the y - axis is "Average change in depth (feet)", with 0 at the top (so a positive value on the y - axis means moving deeper? Wait, no, the label "Shallow" is at the top (0) and "Deep" is at the bottom (50). So the change in depth: in 1982, the depth change is near 0 (shallow), in 2015, the depth change is around 45 feet (since the graph line in 2015 is near 45 on the y - axis). Wait, but let's check the options. The first sub - question answer is 22 miles, the second:

Step1: Analyze depth graph

In 1982, the depth change (from the graph) is near 0. In 2015, the depth change is around 45 feet (by looking at the y - axis of the depth graph, the value in 2015 is approximately 45 feet deeper than in 1982).

Step2: Evaluate options

The options are 45 feet, 22 feet, 10 feet, 30 feet. So the answer for the depth question is 45 feet.

Answer:

s:
First Sub - Question: A. 22 miles
Second Sub - Question: A. 45 feet
