Base your answer to the following question on the diagram below, which represents a specimen observed by a student using the low power objective (100x) of a compound light microscope.

Imagine you were trying to determine whether this object, viewed under the microscope, is living or non living. List one characteristic you would look for to make this determination.

Which instrument was used in the 18th and 19th centuries and helped scientists develop the cell theory?
Ultracentrifuge
Light microscope
Electron microscope
Micro dissecting apparatus
What is common to all cells?
All cells have a cell wall
All cells are photosynthetic
All cells divide to form new cells
All cells have a nucleus
Living organisms can best be distinguished from nonliving things by determining the presence or absence of:
Carbon atoms
Oxygen atoms
Metabolic activities
Chemical reactions
Which activity might lead to damage of a microscope and specimen?
cleaning the ocular and objectives with lens paper
focusing with low power first before moving the high power into position
using the coarse adjustment to focus the specimen under high power
adjusting the diaphragm to obtain more light under high power
The ability to grow in size is characteristic of living organisms. Although an icicle may grow in size over time, it is considered nonliving because there is:
an increase in matter, but no increase in the number of icicles
an interaction between the icicle and the environment
no way for the icicle to move away from heat
no metabolic activity present
Base your answer to question 7 on the graph below and on your knowledge of biology. The graph shows the carbon dioxide (CO2) concentration of the atmosphere since the year 1000.



What was the approximate change in CO2 level from the year 1000 to the year 2000?
an increase of 135 ppm
an increase of 95 ppm
a decrease of 135 ppm
a decrease of 95 ppm
Base your answers to question 8 on the information below and on your knowledge of biology.

"A student designed an experiment to determine if air temperature had an effect on the rate of photosynthesis in corn plants."

Which tool is correctly paired with a procedure that could be used during this experiment?
an electronic balance to measure the volume of soil in which each corn plant is grown
a graduated cylinder to measure 30 mL of water for each plant daily
a metric ruler to determine the mass of each plant each week
a Celsius thermometer to determine the pH of the soil
Base your answers to question 9 on the information below and on your knowledge of biology.

"A student designed an experiment to determine if air temperature had an effect on the rate of photosynthesis in corn plants."

The independent variable in this experiment is the:
air temperature at which the corn plants were grown
amount of carbon dioxide used by the corn plants
volume of oxygen produced by the corn plants
number of corn plants used
Which list contains only abiotic conditions that might be found in a pond ecosystem?
temperature of the water, green plant populations, dissolved minerals in the water
temperature of the water, dissolved oxygen in the water, dissolved minerals in the water
bacteria, dissolved minerals in the water, temperature of the water
dissolved oxygen in the water, fish populations, insect populations
