1. PAGE 2 - Hypothesize: Tests 1-3
Based on your data for structural relationships, which species (X, Y, or Z)
would you hypothesize is most likely to produce Curol?
b. Explain how the evidence from your data table supports your hypothesis. You will test your hypothesis by completing additional tests in the second part of this laboratory activity. Z
Botana Curus and species Z had almost identical characteristics.

It is the same species as Z & different from X & Y.
*Summarize your observations of the number of differences in Table 1.
X = 2 differences, Y = 2 differences, Z = 0 differences Z
BOTANA CURUS MOST CLOSELY RELATED TO SPECIES Z BECAUSE BOTH SPECIES
HAVE THE FOLLOWING SIMILARITIES: A. ENZYME MAKING CUROL, B. SAME PIGMENTATION, C. SCATTERED ARRANGEMENT OF BUNDLES, D. SAME AMINO ACID SEQUENCE, E. 4 SIMILAR SIZED DNA FRAGMENTS.
YES
BOTANA CURUS SHOWED SIMILARITIES BASED ON MOLECULAR EVIDENCE. BOTH REACTED POSITIVELY WITH THE INDICATOR POWDER TEST (FIZZED).

4. MOLECULAR
MOLECULAR EVIDENCE IS MORE HELPFUL THAN STRUCTURAL EVIDENCE. ORGANISMS CAN LOOK ALIKE ON THE SURFACE, BUT MAY HAVE HIDDEN MOLECULAR DIFFERENCES.
THEY HAVE DNA, LEAVES, SEEDS, OTHER AMINO ACID SEQUENCES…

5. THESE COMMON CHARACTERISTICS ARE MOST LIKELY
PAGE 6:
THESE COMMON CHARACTERISTICS ARE MOST LIKELY
DUE TO COMMON ANCESTRY. 2
THIS TREE BECAUSE IT SHOWS Z & BOTANA CURUS CLOSER TOGETHER ON THE TREE. THE PROXIMITY ON THE TREE REPRESENTS A CLOSER GENETIC RELATIONSHIP.

MAKES CUROL, USEFUL FOR AGRICULTURE, OTHER MEDICAL PURPOSES, OTHER SPECIES MAY DEPEND ON IT.
EXPENSIVE, MAY NOT BE ABLE TO SAVE IT, IT’S SMALL & GROWS SLOWLY,
OTHER PLANTS MAY BE A BETTER SOURCE OF CUROL.
