SAMPLE TOURNAMENT #3

Station A: Microscopy

1. List the powers of the objectives for this microscope.

2. List the range of magnification (lowest to highest) for this microscope.

Place the transparent ruler on the stage, hold it down with the stage

clips and focus on the metric scale with the scanning (5X) power objective.

Hint: Applying gentle pressure to the free end of the

ruler will help to adjust for the thickness of the ruler and allow

better focus.

3. What is the diameter of the scanning (5X) field of this microscope in millimeters ?

in micrometers?

4. Assuming this photo of hydra (below) was taken using the scanning power field of

this microscope, what is the length in micrometers of the bud in mm? in mcm?

5. A chain of spirogyra is observed under low power (10X) of this microscope. A student

counts 6 cells along the diameter of the field of view. How many cells should be

visible along the scanning power (5X) field of view?

Materials: Microscope with 10X ocular and 5X, 10X, 40X and 100X objectives, clear mm ruler,

hydra photo.

12. How will the shoot and root grow for seed “D” ?.

13. What type of geotropism will the corn roots exhibit? (positive or negative).

14. What type of phototropism will the corn shoots exhibit? (positive or negative)

15. How might the germination of these seeds be affected if the experiment were conducted

in outer space? Why?

Station F: Punnett Square Analysis

Examine the Punnett Square below and answer the questions.

Background: Genotype is the gene combination and phenotype is the appearance of the trait.

Capital letters indicate dominant alleles and lower case letters indicate recessive alleles.

In race horses, black hair (B) is dominant over chestnut hair (b) and a trotting gait (T) is

dominant over a pacing gait (t). Tow heterozygous black trotters are mated (BbTt X Bb Tt).

26. How many of the genotypes in the Punnett Square will produce a phenotype

with black hair?

27. How many of the genotypes in the Punnett Square will produce a phenotype

with a pacing gait?

28. How many of the genotypes in the Punnett Square will produce a phenotype

with chestnut hair and a trotting gait?

29. How many of the genotypes in the Punnett Square will produce a phenotype

with chestnut hair and a pacing gait?

30.

of this limb?

32. Which animal has both the ulna and radius short and thick? What is the function of this

limb?

33. Which animal has the ulna long and straight with the radius small and straight? What is

the function the this limb?

34. These animals have similar anatomical structures modified for different structures. What

term describes this situation?
