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

Maintain an internal temperature (homeostasis)

The title of a graph should describe:

How the independent variable affects the dependent variable

The data from the Giraffe Case Study did NOT support the hypotheses that:

Giraffes have long necks to reach high food sources, Giraffes have long necks to have an advantage during the dry season

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

Focus only on the results that make sense

Answers

1
Prokaryotic, means:
before nucleus (no nucleus)
wants to be carried
in support of nucleus
before body
2
Which variable usually goes on the x-axis?
Controlled
Dependent
Control Group
Independent
3
What does it mean if bacteria are sensitive to an antibiotic?
The antibiotic kills or inhibits the bacteria's growth
The bacteria is not resistant to the antibiotic
All of the above
It will not grow near the antibiotic strip
4
The thing that you change (have different levels for) between your treatment groups is your:
Control
Controlled Variables
Dependent Variable
Independent Variable
5
What was the Independent Variable in the Bacteria lab?
Zone of inhibition
Incubator Temperature at 35C
Type of Antibiotic
Type of Bacteria
6
Bacteria are what type of cells?
Multicellular
Prokaryotic
Eukaryotic
Gross
7
When we shiver, it is an example of which characteristic of life?
Need materials for energy
Changing over time (evolve)
Are made up of cells
Maintain an internal temperature (homeostasis)
8
Bacteria that are spherical shaped are called
Spirochete
Cocci
Triangular
Bacilli
9
The group that does not receive the treatment in an experiment is called the:
Dependent Variable
Control
Independent Variable
Controlled Variables
10
The title of a graph should describe:
The Independent variable vs. Dependent variable
How the dependent variable affects your dependent variable
A question
How the independent variable affects the dependent variable
11
The data from the Giraffe Case Study did NOT support the hypotheses that:
Giraffes have long necks for males to fight each other
Males who win fights have more access to females
Giraffes have long necks to reach high food sources
Giraffes have long necks to have an advantage during the dry season
12

mm3
in2
cm2
mm2
14
All of the following are steps in the scientific method except:
Create a controlled experiment
Analyze Results
Observe and Question
Focus only on the results that make sense
15
All living things
change over time (evolve)
share a universal genetic code (DNA)
are made up of cells
all of the above
16
The thing that you measure as a result of your experiment is your:
Independent Variable
Controlled Variables
Dependent Variable
Control Group
17
Bacteria that are spiral shaped are called
Round
Bacilli
Spirochetes
Cocci
18
A plant budding to form a new plant is an example of this characteristic of life:
Changing over time (evolve)
Asexual Reproduction
Need for material for energy
Growth and Development
19
Metabolism describes the
Sharing a universal genetic code
Responding to the environment
Maintaining an internal temperature
Need for materials for energy
