Textbook Question
Chapter 1.3, Problem 4CC
WHAT IF? Ø In the deserts of New Mexico, the soils are mostly sandy, with occasional regions of black rock derived from lava flows that occurred about 1,000 years ago. Mice are found in both sandy and rocky areas, and owls are known predators. What might you expect about coat color in these two mouse populations? Explain. How would you use this ecosystem to further test the Camouflage hypothesis?

Imagine you are a botanist. Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI).
Field Notes: Specimen collected from shaded area along stream in South Cumberland State Park (Grundy County, TN).
Laboratory Analysis:
Body: Large leaves emerging from underground rhizome.
Size: 63 cm
Chromosomal Analysis: Plant body is diploid—chromosome number of 44.
Lignin test: Positive
Cuticle: Present
Leaves: Present—large with branched veins. Underside has sori (containing haploid spores).
Roots: Present—branch from the inside.
Stem: Present—vascular tissue (xylem & phloem) present.
Life History: Diploid sporophyte dominant generation. Haploid spores germinate into heart-shaped, haploid, gametophyte. Water required for fertilization; no seed is produced. Diploid zygote develops into sporophyte.
