Base your answers to questions 46 through 49 on the information and data table below and on your knowledge of biology.

Birds colliding with aircraft either on the ground or in the air create problems for the Air Force. An organization known as BASH (Bird Aircraft Strike Hazard) studied the impact of birds colliding with aircraft. In 2001, there were 3854 bird collisions reported at a total cost to the Air Force of over 31 million dollars in damage—approximately eight thousand dollars per collision. August, September, and October were the busiest months with 1442 collisions. Nearly 50% of all these collisions occurred in the airfield environment, an environment that can most easily be controlled.

The top five species of birds involved in these collisions are listed in the data table below.

Directions (46–47): Using the information in the data table, construct a bar graph on the grid, following the directions below.

46 Mark an appropriate scale on the axis labeled “Number of Collisions.” [1]

47 Construct vertical bars to represent the data. Shade in each bar. [1]

48 Is the problem with birds and aircraft limited to birds living on or near airport grounds? Support your answer using information from the passage. [1]

49 State one possible reason that the greatest number of bird collisions occurs during

August, September, and October. [1]

Base your answers to questions 51 through 55 on the information below and on your knowledge of biology. The average level of carbon dioxide in the atmosphere has been measured for the past several decades. The data collected are shown in the table below.

Directions (51 and 52): Using the information in the data table, construct a line graph

on the grid on the next page, following the directions below.

51 Mark an appropriate scale on each labeled axis. [1]

52 Plot the data on the grid. Surround each point with a small circle and connect the

points. [1]

53 Identify one specific human activity that could be responsible for the change in carbon dioxide levels from 1960 to 2000. [1]

55 Calculate the net change in CO2 level in parts per million (ppm) during the years 1960

through 2000. [1]

______ppm
