Chapter 1 Biology Test
What is the difference between a theory and a hypothesis?
A theory is a statement or answer that has been tested many times and had the same result each time which a hypothesis is a education guess with research behind that can be tested
Compare and contrast an autotroph and heterotroph. Provide an example of each
Autotroph can feed themselves while heterotroph receive their food from a second source
(T/F) The vast majority of multicellular organisms reproduce asexually
False, sexually
Why is Rabbit B essential to this experiment?
You would not know if the experiment made a difference or not if you don't have anything to compare it to
Biologists who study cactuses and African violets would be called
botomist
What is the term given to a group of cells that develops from a single original cell
cell culture
What technique is used to separate different cell parts
cell fractionation
The information you gather during an experiment is called your
data
Which level of organization included all of the other levels
ecosystem
You have an (endoskeleton/exoskeleton)
endoskeleton
(T/F) The smallest units that are considered to be alive are organisms
False, cells
(T/F) "The bird has brown spots on its wings" is an example of an inference"
False, qualitative observation
In science, a hypothesis is useful only if
it can be tested
Biology is the study of
the living world
Interpret Graphs In Figure 1-1, which rabbit is the control?
B
Which of the following is NOT a part of how scientists work
guessing
What are the differences between sexual and asexual reproduction?
Sexual reproduction requires 2 parent cells and asxeual only requires 1 parent cell
Describe the difference between a stimulus and a response. Give an example of each
Stimulus: change the environment Response: reaction to that change
Before completing the experiment in Figure 1-1, the scientist made a hypothesis. What is the hypothesis she is testing?
The body parts of the rabbit that become colder will have a change of fur color to black
Can a theory chance over time
Yes, if new observations are made and tested towards the theory they could be added
How would you determine whether something is living or non living
You could determine of something is living or not if it has any cells or if it can reproduce or not
As the result of an experiment you reject your hypothesis. Explain why you should not consider your efforts a waste of time
You shouldn't consider if a waste of time because you could've found out something you didn't know
The process by which organisms keep their internal conditions fairly constant is called
homeostasis
You suggest that the presence of water could be accelerate the growth of bread mold. This is a(an)
hypothesis
Impulses traveling from one cell to another is an (intercellular/intracellular) activity
intercellular
Which the following characteristic of living things best explains why bird fly south for the winter
living things respond to their enviroments
A biologists is doing research on a pack of wolves living in a particular section of a forest in northern Minnesota. What level of organizations could this biologists be studying?
population
What is the term for a group of organisms of one type living in the same place
population
Shivering is an example of a
response
The name given to the idea that life could arise form non living matter is
spontaneous generation
Draw Conclusions Based on your observations of Figure 1-1, conclude what effect temperature has on Himalayan rabbits.
temperature affects color
Interpret Graphs In Figure 1-1, what is the variable in this experiment?
the ice pack
Which of the following is a valid hypothesis for why a plant appears to be dying
the plant is not being watered enough, the plant is being watered too much, the plant is receiving too much sunlight
Scientists publish details of important experiments so that
their work can be repeated, their experimental procedures can be reviewed, others can try to reproduce the results
A well tested explanation that unifies a broad range of observations is an(an)
theory
Which of the following is NOT a goal of science?
to use data to support a particular point of view
A controlled experiment allows the scientist to isolate and test
a single variable
Which of the following is NOT a characteristic of all living things
ability to move
You do not need a partner for (sexual/asexual) reproduction
asexual
Using proper equipment is necessary when testing hypothesis. How was the flask Pasteur used in testing the hypothesis of spontaneous generation essential to his success?
Curve air and trapped , kept microorganisms out
Which of the following terms included all the others
biologists
What is the term for the part of the Earth that contains all ecosystems
biosphere
A (disaccharide/ polysaccharide) contains more (sugar/fat) molecules
polusaccharide;sugar
Bacteria and viruses are (microscopic/macrosopic)
microscopic
You are an (unicellular/multicellular)
multicellular
