Question 8

Which of the following does NOT represent homeostasis?

Accepted Answer

A)  Sensors detect CO2 levels in the blood and trigger an increase or decrease in the rate of breathing. 
B)  When body temperature drops, you shiver to generate heat; when your body heats up, you sweat and the evaporation cools you. 
C)  Feelings of hunger and then fullness affect the length of time and quantity of food you eat, keeping your weight near a "set point." 
D)  Energy is captured by plants, then transferred to consumers and decomposers, and eventually lost as heat. 
E)  Cells adjusting the openings on the bottom of leaves respond to differences in water stress in order to maintain moisture inside the leaf.

Question 10

Humans have an exaggerated impact on the ecosystem through their use of extra sources of energy and raw materials, and the production of extra wastes that must be handled.

Accepted Answer

A) True 
 B)False

Question 11

Living organisms are composed only of organic elements, whereas nonliving things are made up of inorganic elements.

Accepted Answer

A) True 
 B)False

Question 12

Dr. James isolated Staphylococcus aureus, a type of bacteria, from the leg wound of a ten-year-old boy. He suspected these bacteria would grow better at body temperature than room temperature (72 $\degree$F), but thought that he should collect data to support his thinking. Dr. James introduced the same number of Staphylococcus bacteria into each of six test tubes containing the same type and amount of nutrient broth. Three test tubes were incubated at 98.6 $\degree$F (Group 1), while three test tubes (Group 2) sat at 72 $\degree$F. After 24 hours, Dr. James compared the turbidity (indicative of growth) of all six tubes and rated each on a scale of 0 - 4. 0 indicates no turbidity (no growth), while 4 indicates high turbidity (high growth). The following data was collected:

Yes, this may be considered a controlled
