While researching bacterial growth in 1928, Alexander Fleming observed that the
presence of a specific type of mold resulted in the death of bacterial colonies that came
in contact with the mold. This discovery led directly to which of the following advances?
The use of antibiotics such as penicillin for the treatment of infection
The germ theory of disease and the importance of hand washing
The development of vaccines as a way of preventing the acquisition of disease
The process of pasteurization as a way to eliminate bacteria and yeasts in milk -
Answer-The use of antibiotics such as penicillin for the treatment of infection
As part of a unit about disease prevention, students are learning about how researchers
link the presents of a certain strain of bacteria to the occurrence of a specific disease.
Which of the following is the strongest evidence that a strain of bacteria is the cause of
a particular disease?
The bacteria are present in abundance in geographic areas where the disease is
prevalent
The bacteria have been shown to be susceptible to the lethal effects of antibiotics such
as penicillin
The bacteria occur in a higher frequency in children whose parents were exposed to the
disease.
The bacteria can be isolated from all individuals exhibiting disease symptoms but not
from unaffected individuals - Answer-The bacteria can be isolated from all individuals
exhibiting disease symptoms but not from unaffected individuals
A second grade teacher plans to start a vegetable garden to help students learn about
the resources required for plant growth. The teacher uses stakes and string to make a 5
foot by 5 foot plot on the ground, but determines it would only provide enough space for
each student to grow one plant. In order for each student to have enough space to grow
two plants, the teacher plans to double the area of the first plot. What will the total area
of the enlarged plot?

an anatomy term
Asking students to make a claim about an animals classification and to give the reasons
for their assertion
showing a video that introduces students to representative animals from each of the
biological classes
surveying student ideas about specific animal classifications and organizing the results
into a data table - Answer-Asking students to make a claim about an animals
classification and to give the reasons for their assertion

not disturbed by it. The relationship between the small bird and elephant is an example
of:
A. Parasitism
B. Mutualism
C. Predation
D. Commensalism - Answer-D. Commensalism
