13) 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 (72f), 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 98.6f (group 1), while three test tubes (group 2) sat at 72f. 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:
the dependent (responding) variable in this experiment is:
a. the temperature
b. growth of bacteria, as indicated by the turbidity in the test tubes
c. the time that the test tubes were allowed to sit
d. amount of initial inoculum, or number of bacteria introduced into each test tube
14) which of the following statements applies to mitosis but not to cytokinesis?
a. it contains a checkpoint that will evaluate the quality of the cell
b. requires a large amount of atp in order for the cellular mechanisms to function
c. if it is disrupted it can lead to an abnormal cell
d. it results in two daughter cells that are half the size of the original cell
15) the digestive juices found in the stomach include
a. insulin and bile.
b. pepsin and hydrochloric acid.
c. sodium bicarbonate and hydrochloric acid.
d. pancreatic and salivary amylase.
e. trypsin and maltase.
