Question
Chapter 46, Problem 1S
Summary Introduction
To determine:
Whether it would be better to make a space-exploration vehicle with a hydrostatic skeleton or an exoskeleton for a planet with gravity greater than Earth and why.
Introduction:
In hydrostatic skeleton, the animal’s body has a fluid-filled cavity. Contraction of this cavity helps in locomotion like in earthworms. However, in the animals with an exoskeleton, the body has a hard protective outer layer made of chitin called the exoskeleton like in insects.

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.
