Objective numbers correspond to the State Priority Academic Student Skills (PASS) standards and
objectives. This number is also referenced with the local objective’s verbal description on the pacing guide and on
student benchmark reports.

Process 3.5

1.
Ned finished an experiment and still had some unused chemical solution. Which of these is the best thing
for Ned to do with the extra solution?

A Pour it down the sink

B Pour it back into its original container

C Dispose of it as directed by his teacher.

D Put it in a beaker and place it under a fume hood.

3.
In many classrooms, lab exercises are performed by small groups of students. The students are
supervised by a teacher who monitors each group’s progress periodically.

When should you notify your instructor of unsafe conditions in the lab?

A immediately

B after the lab period

C after your data has been collected

D when the instructor comes by your station

Use the information to answer questions 4-6.

A biology student wants to study how animal cells react when places in distilled water and in a salt
solution. The student used the following procedure:
1) Place a small sample of cells on a microscope slide and place a cover slip over the sample. Add
a few drops of distilled water under the cover slip.
2) Observe the cells in the distilled water solution under a microscope.
3) Place a small sample of cells on a microscope slide and place a cover slip over the sample. Add
a few drops of 20% salt solution under the cover slip.
4) Observe the cells in the salt solution under a microscope.

4.
What is the dependent variable in this experiment?

A the salt concentration

B the number of cells in the sample

C the type of animal that the cells come from

D the movement of water across the cell membrane

5.
Which of these will most likely happen to the cells when they are placed in distilled water?

A the cells will shrink and shrivel up

B the cells will enlarge until they burst

C the cell membrane will thicken

D the cells will remain unchanged
6.
The student observed that the cells in the 20% salt solution changed in size. Which of these best explains
what is causing this change?

A water from the solution is moving into the cells

B water is moving out of the cells into the surrounding solution

C salts from the solution are moving into the cells

D salts are moving out of the cells into the surrounding solution

15.
Robert is conducting breeding experiments with mice. He crossed two brown mice and found that 25%
of their offspring were white.

Which conclusion from this experiment is most logical?

A White color is dominant over brown color

B One of the parent mice is homozygous for the dominant allele

C All of the offspring carry two copies of the recessive allele

D The white offspring are homozygous for the recessive allele

In a certain group of lab mice black fur is dominant and brown fur is recessive. If two heterozygous mice
mate and produce 16 offspring, how many of the offspring will probably have brown fur?

A 0

B 4

C 8
