The title of your graph should describe:

How your independent variable affects the dependent variable

When we shiver, it is an example of which characteristic of life?

Maintain an internal temperature

How did we calculate the zone of inhibition in our bacteria lab?

Used the diameter of the ZI, then used the formula π(d/2)^2

All of the following are steps in the scientific method except:

Focus only on the results that make sense

What was our Independent Variable in our Bacteria lab?

Both type of bacteria and type of antibiotic

Answers

1
The thing that you change between your treatment groups is your:
Controlled Variables
Independent Variable
Control
Dependent Variable
2
All living things
all of the above
are made up of cells
share a universal genetic code
change over time (evolve)
3
A plant needing to be in the sun to grow is an example of which characteristic of life?
Share a universal genetic code
Need for materials for energy
Maintain an internal temperature
Respond to their environment
4
Bacteria that are rod shaped are called:
Bacilli
Cocci
Spirochete
Cylindrical
5
Which variable goes on the x-axis
Controlled
Dependent
Independent (or time if used)
6
What is the literal definition of isotonic?
frozen concentration
same concentration
under concentration
over concentration
7
Bacteria are Prokaryotic, which (when we use our etymology) literally means:
before body
before nucleus
wants to be carried
in support of nucleus
8
The title of your graph should describe:
How your dependent variable affects your dependent variable
Be a question
How your independent variable affects the dependent variable
be set up: Independent variable vs. Dependent variable
9
The thing that you measure as a result of your experiment is your:
Controlled Variables
Control Group
Dependent Variable
Independent Variable
10
A plant budding to form a new plant is an example of this characteristic of life:
Growth and Development
Change over time
Need for material for energy
Reproduction
11
When we shiver, it is an example of which characteristic of life?
Are made up of cells
Maintain an internal temperature
React to their environment
Need materials for energy
12
What is the literal definition of hypoglycemia?
over nucleus condition
over sugar conditioin
under sight condition
under sugar condition
13
We pipetted this amount of bacteria into our petri dishes:
100 microliters
15 microliters
10 microliters
0.5 liters
14
The group that does not receive the treatment in an experiment is called the:
Controlled Variables
Independent Variable
Dependent Variable
Control
15
How did we calculate the zone of inhibition in our bacteria lab?
Calculated the area of the petri dish
Calculated the volume of the space around the antibiotic
Used the diameter of the ZI, then used the formula π(d/2)^2
We measured the diameter in inches
16
All of the following are steps in the scientific method except:
Create a controlled experiment
Analyze Results
Focus only on the results that make sense
Make an inference
17
What was our Independent Variable in our Bacteria lab?
Type of Antibiotic
Zone of inhibition
Both type of bacteria and type of antibiotic
Type of Bacteria
18
The units for our zone of inhibition (and our dependent variable label on our y-axis) was:
mm2
in2
mm3
cm2
19
What does it mean if a bacteria is sensitive to an antibiotic?
It will not grow near the antibiotic strip
The bacteria is not resistant to the antibiotic
The antibiotic kills or inhibits the bacteria's growth
All of the above
20
What is the literal meaning of hydrolysis
hydrogen kill
water body
water explode
water kill
