1

You performed this experiment using this set-up as a respirometer. The control had ______________in the tube.

1

Name one of the constants in this experiment.

1

The independent variable in this experiment was the...

1

The dependent variable in this experiment was the amount of _________that was used by the peas.

1

The type of data collected was quantitative or qualitative?

1

The cotton ball soaked with KOH was designed to absorb ______________ produced by the pea seeds.

1

A hypothesis for this experiment could be: If germination is initiated in the hydrated peas, then the amount of respiration will increase.

You learned how to measure volume by using water displacement in a graduated cylinder. Look at the 2 graduated cylinders. The one on the right was filled to 50 ml, this is the amount of water that was in the 2nd graduated cylinder prior to putting glass marbles in it. Seven marbles were added to the 2nd graduated cylinder. Assume that each of the marbles are completely identical. What is the volume of one of the marbles? A calculator is provided if you need it.

Find Location #2: Look into the microscope and view the specimen. If it is a tiny bit out of focus you may use the fine adjustment knob to make it clearer to you. You are told that the diameter of the scanning objective is 4.5 mm. What is the diameter of the specimen?

1

Using the same microscope: What is the total magnification of the specimen?

1

Using the same microscope: What is the magnification of the ocular lens (eyepiece)?

1

Using the same microscope: What type of cells are represented in this prepared slide?

1

Using the same microscope: What can you use to focus the specimen under this lens objective?

Go to Sign with #3 Location on it. Draw a punnet square between two heterozygous
organisms. Use the letter D to represent the trait. When finished, raise your
hand so I can come and grade it.

1

The punnet square shows a probability of 75% of the dominant phenotype in the offspring.

Find Question #15. This graphic is called aand is most likely showing a _____trait.

1

If #15 child had the trait (instead of not having it), then Mom would have to be a carrier.

Find Location #4 - You have an organism that has two chromosomes. Use the
materials available to you to show what happens to them in the S phase of the
cell cycle. Raise your hand when finished, so I can grade you.

Find Location #5 - Using the materials provided show what happens during
spermatogensis if there is nondisjunction during Meiosis I. Raise your hand when
finished, so I can grade you.

Find Location #7: create a sequence with the tRNAs in a row; match up the tRNA
with its appropriate amino acid; when completed raise your hand and I will come
and grade you

Find Location #8 - match up the correct tRNAs with the mRNA strand; raise your
hand when finished so I can grade you

1

Find Location #9 - look at the materials placed on the table - What process has just occurred?

1

DNA is copied from the 3' to 5' end.

1

DNA bases are __, , , and _. mRNA switches the _ for a ___.

Find Location #10. Take a pH reading of the solution in the beaker. Based on the pH reading, the solution is a(n)

1

Using the pH reading from Location #10, the hydrogen ion concentration in this solution is low.

1

Find Location #11. Which test tube is an example of an Isotonic solution added to sheep blood cells?

1

Find Location #12. This is an example of

2

Locate the mitochondrion in this picture of a cell and draw a circle around it. Then, type/write out the equation for cellular respiration next to it.

Find Location #13 next to a microscope. Use the slide to locate and identify a
cell in metaphase or anaphase or telephase. Bring the specimen into focus under
the highest magnification. Turn the arrow inside the eyepiece so that the tip
points directly
