Chapter 1 Review


1.      List the eight characteristics of life:


2.      Define homeostasis.   Give two examples of an organism maintaining homeostasis.


3.      When a piece of food is placed on a slide with Paramecium, the Paramecium will swim toward the food. Identify the stimulus and the response in this situation.  Is the response positive (toward the stimulus) or negative (away from the stimulus)?


4.      Give three other examples of a stimulus and a response.


5.      Define metabolism. Give an example of metabolism in your body. What is usually the end product of metabolism?


6.      Define evolution.


7.      What is the difference between sexual and asexual reproduction?


8.      Complete the following table about the six kingdoms of organisms.



Type of Cell

Cell Number

Mode of Nutrition



























9.      What is the scientific method?  Name the six steps of the scientific method.



10.  What is a  hypotheisis?




11.  A scientist observed that when it was a very cold spring, all of the young turtles that hatched were male.

a. What is the problem from this observation (must be a question)?



b. Create a hypothesis for this problem (must be in if… then… form and answer the problem).



12.  What is a control group?


13.  What is the purpose of the control group?




14.  Explain the difference between the manipulated and responding variables. Which one goes on the x-axis? Y-axis?




15.  What is data? Identify each of the following as quantitative data or qualitative data and explain why:

a. Sam counted 10 new leaves on plant #1 and 4 new leaves on plant #2.


b. Kim observed that earthworms are moist, ringed and have a lighter colored band near the anterior end.


c. Ron found the average height of group #1 to be 9.26 cm and group #2 to be 11.57 cm.


16.  A student set up an experiment to test the effect of different colored light on the growth of lily plants. Plant #1 was exposed to red light, plant #2 was exposed to blue light and plant #3 was exposed to white light.  All of the plants were allowed to grow for two weeks in 21 °C and given 500 mL of water a day. Identify each of the following:


a.       Control group(s):


b.      Experimental group(s):



c.       Independent (manipulated) variable:



d.      Dependent (responding) variable:



17.  How many manipulated variables should be in a controlled experiment?



18.  Why do scientists publish their experiments in scientific journals?




19.  Define a hypothesis. Define a theory. Define a scientific law.





20.  What is the biggest difference between a hypothesis and a theory?



21.  Science is best described as _____________________________________________.


22.  Name the four attitudes that make a person a good scientist.



23.  Describe what is meant by bias.



24.  Which variable is put on the x-axis of a graph? Which variable is put on the y-axis?



25.  What is the formula for appropriately titling a graph?



26.  Why do scientists all use the metric system?



27.  Make the following conversions within the metric system using the following chart:


k                 h                 dk               m                d                 c        m




a.  0.00027 g = __________   mg


b.  586 dL = ____________ dkL


c. 10.4 cm3 = _________ mL


d. 65.34 m = ________ mm
