In a classification system, organisms may be grouped according to likenesses of their body parts, or
. They may also be classified according to the type of cells they have. For example, some cells do
not have a true nucleus and are called
; some cells are
and
have a nucleus. Classifying organisms shows that there are a wide variety of living things, that there is much
among organisms. Organisms exhibit a wide variety of traits. Many of these traits are
, which enable the organisms to survive in their surroundings.

environment will affect the cell and may cause death to the cell or organism. Some events that affect the cell

(contamination
of the environment); destruction of areas where organisms live, called
; and

Exercise 2: Given the following information, organize the data into a table. Use the blank area provided in Figure 1 to
draw in the necessary columns and rows. Then interpret the data and answer the questions that follow.
On an expedition around the world, several scientists collected the venom of various snakes. One of the tests that the
scientists conducted determined the toxicity of the venom of each snake. Other data obtained by the scientists included
the mortality percentage, or relative death rate, from the bites of various snakes.
The snakes observed were the (1) southern United States copperhead, (2) western diamondback rattlesnake, (3) eastern
coral snake, (4) king cobra, (5) Indian krait, (6) European viper, (7) bushmaster, (8) fer-de-lance, (9) black-necked cobra,
and (10) puff adder.
The mortality percentage of people bitten by snakes varied from 100% to less than 1%. The scientists noted the mortality
percentage for each of the snakes was (1) less than 1 %, (2) 5-15 %, (3) 5-20 %, (4) greater than 40 %, (5) 77 %, (6) 1-5 %,
(7) usually 100 %, (8) 10-20 %, (9) 11-40 %,and (10) 11-40 %.

1. Which snake’s venom has the highest mortality rate?
2. Which snake’s venom has the lowest mortality rate?
3. From the information recorded, can you determine the snake whose venom works most rapidly? The least
rapidly?
4. Which two snakes’ venom have the same mortality rate?
5. How many types of snakes were observed?
Graphing Skills
Graphing is an important procedure used by scientist to display the data that is collected during a controlled
experiment. There are three main types of graphs:
Pie/circle graphs: Used to show parts of a whole.
Bar graphs: Used to compare amounts.
Line graphs: Use to show the change of one piece of information as it relates to another change.
Both bar and line graphs have an “X” axis (horizontal) and a “Y” axis (vertical).
Parts of a Graph:
Title: Summarizes information being represented in ANY graph.
Independent Variable: The variable that is controlled by the experimenter, such as, time, dates,
depth, and temperature. This is placed on the X axis.
Dependent Variable: The variable that is directly affected by the I.V. It is the result of what
happens as time, dates, depth and temperature are changed. This is placed on the Y axis.
Scales for each Variable: In constructing a graph, one needs to know where to plot the points representing
the data. In order to do this a scale must be employed to include all the data points. This must also take up
a conservative amount of space. It is not suggested to have a run on scale making the graph too hard to
manage. The scales should start with 0 and climb in intervals such as, multiples of 2, 5, 10, 20, 25, etc…the
scale of numbers will be determined by your data values.
Legend: A short descriptive narrative concerning the graph’s data. It should be short and concise
and placed under the graph.
For any set of data, you will need to determine the following:
Mean: This is determined by adding all the numbers in a set of data and then dividing by the
number of values.
Median*: This is the middle number in a set of data. If the there is an even set of numbers in the
data, then take the average of the two middle numbers.
Ex: 2, 3, 4, 8, 12, 16, 20 median = 8
Ex: 3, 5, 8, 11, 17, 19, 27, 30 median is 11 + 17 = 28/2 = 14
Mode*: This is the number that occurs most often in a set of data.
Ex: 3, 4, 6, 6, 7, 9,9,9, 12, 12, 15 mode = 9
* To determine median and mode, the numbers in the set of data must be put in numerical order.
Extrapolate: extending the graph, along the same slope, above or below measured data.
Interpolate: predicting data between two measured points on the graph
