6. Characteristics of Living Things
a)
b)
Which characteristic of life is defined as: “the
tendency of a system, especially the physiological
system of higher animals, to maintain internal
stability”?
Which characteristic can be described as:
“Populations of living organisms have the ability to
adapt to their environment. Changes occur in
populations, and the organisms in the population
become better able to metabolize, respond, and
reproduce. They develop abilities to cope with their
environment that their ancestors did not have”?
7. Characteristics of Living Things

One characteristic of living things is the display of
organization within their bodies.
a) Give an example of an organ system, organ, and tissue within the human
body.
b) Which is the most specific (smallest) level of cellular organization?
8. Scientific Method

What is the
experimental variable
in the experiment
illustrated to the right?
9. Scientific Method

Look at the data
collected in the
plant experiment. Is
the data qualitative
or quantitative?
10. Scientific Method

According to the data table, what is the optimum
amount of water to be added to the plant?
11. Scientific Method

Look at the labeled graph below. What is the
dependent variable in the experiment? What axis
always represents the dependent variable?
12. Scientific Method

In 1928, Sir Alexander Fleming was studying Staphylococcus
bacteria growing in culture dishes. He noticed that a mold
called Penicillium was also growing in some of the dishes. A
clear area existed around the mold because all the bacteria
that had grown in this area had died. In the culture dishes
without the mold, no clear areas were present. Fleming
hypothesized that the mold must be producing a chemical
that killed the bacteria. He decided to isolate this substance
and test it to see if it would kill bacteria. Fleming
transferred the mold to a nutrient broth solution. This solution
contained all the materials the mold needed to grow. After
the mold grew, he removed it from the nutrient broth.
Fleming then added the nutrient broth in which the mold had
grown to a culture of bacteria.
What is Sir Alexander Fleming’s experimental problem?
