Part A: Collect Data
Question 1
Closely examine each fossil . Then, complete the table to record your observations, which should include these
details:
• Predicted kingdom
: Classify the fossil based on whether it shows the characteristics of a plant, animal, or fungi.
• Physical characteristics: Note the shape, patterns, and any other physical features of the fossils.
• Predictions about its environment: Based on the features of the fossil, what type of environment did the
organism live in? Was it an aquatic organism or a land organism? Did it require a hot or cold climate?
• Similar living organisms: Try to identify a present-day organism that resembles your fossil. What characteristics
do the two organisms share? What characteristics are different?

what trophic level is the thrush in?
The Newcastle Hare also has a single gene responsible for ear erectness. The allele E is dominant and produces a protein resulting in an erect pointy ear, while the recessive form (e) results in the lack of this protein and drooping ears. If a droopy eared, hissing male mates with a female who is heterozygous for both traits, answer the following questions:
i. What is the probability that any offspring will have droopy ears? (Blank 1)
ii. What is the probability that any offspring will be both droopy eared and hissing? (Blank 2)
iii. What is the probability that any offspring will be erect eared screamers?
iv. What are all the possible genotypes for the progeny (list them)?
