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.
A 10 ml
B 1 ml
C 1.4 ml
D 0.14 ml

A 4.5 micrometers
B 45 micrometers
C 450 micrometers

A course adjustment knob
B fine adjustment knob
C the course and fine adjustment knobs
D close the diaphragm to increase depth of the specimen
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.

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

Continue using the information at Location #5. If these gametes were crossed with a normal female, some of the offspring would be viable and some wouldn't.
True
False

Find Location #6This specimen is a good example of the result of a
A monohybrid cross
B dihybrid cross
C polypeptide cross
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

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
