Textbook Question
Chapter 15, Problem 4ILQ
Watch this video (http://openstaxcollege.org/l/pupillary) to learn about the pupillary reflexes. The pupillary light reflex involves sensory input through the optic nerve and motor response through the oculomotor nerve to the ciliary ganglion, which projects to the circular fibers of the iris. As shown in this short animation, pupils will constrict to limit the amount of light falling on the retina under bright lighting conditions. What constitutes the afferent and efferent branches of the competing reflex (dilation)?

Hydrogen bonds play an important role in stabilizing and organizing biological macromolecules. Consider the four macromolecules discussed. Describe three examples where hydrogen bond formation affects the form or function of the macromolecule.
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.
