Water Regulation and Adaptation Chap. 6 I. Water potential A. components B. water flow
II. Water balance A. water loss B. water gain III. Regulation & Adaptations plants & animals A. Terrestrial
B. Aquatic 1. Isoosmotic 2. Hypoosmotic 3. Hyperosmotic
Which way does water flow? Questions 1. How do you get water to the top of a 300 ft. tall redwood tree?
2. Why is soil under some trees more wet in the morning than the previous afternoon? Hint: it comes from the roots, not from rainfall. 3. Why are salmon so spectacular physiologically? (what makes going from fresh to salt water and
back again so remarkable)? Global Warming effects change in precipitation I. Water potential ()
A.The components = p + s + m + g B. Water flow Example up a tree,
down a water potential gradient Units = MPa Soil : Lower, more negative
Tension-cohesion mechanism Effect of water content on soil water
Effect of water content on soil : different soil types Effect of Relative Humidity on Air

II. Water balance W = Wg - Wl A. Water loss - Terrestrial organisms 1. Evaporation
Vapor pressure deficit (VPD) B. Water gain Drinking/root uptake
Uptake via body surface Water in food W = Wg - Wl Oxidation (metabolic water)
III. Regulation & Adaptations A. Terrestrial high potential for water loss 1. Intake metabolic water

B. Aquatic 5 Questions 1. Terms: Iso-osmotic (isomotic), hypo-osmotic (hyposmotic), hyperosmotic. 2. To what situations do these refer?
3. What do animals (fish, invertebrates) need to do in marine environments to maintain their water and salt balances? 4. What do animals (fish, inverts.) need to do in freshwater environments to maintain their water
and salt balances? 5. What about anadromous fish such as salmon? How must their physiology change when migrating from fresh to salt water and vice versa?
An end mark is also known as punctuation, and comes at the end of a sentence. It lets you know when to stop. What are the different kinds of end marks? An exclamation mark shows excitement or feeling. That is...
Your AE should be 80 hours at one site, whether that's at a specific organization, focused on a particular research project, or engaging with a specific faculty member. The 80 hours do not need to be completed all at once,...

Hamlet's anger towards his mother propel him to characterise all woman as weak and unreliable. Feminist views would say that Ophelia acts as a strong female presence as she is used as a 'pawn' by Hamlet, shadowed in the society...
The Neo-Classical Period 1750-1827 Jacques-Louis David Jean-Auguste-Dominique Ingres Thomas Jefferson Cultural Circumstances When the buried ruins of Pompeii and Herculaneum were found in the 1700's the world gained renewed interest in the Classical period and art forms.
The cult statue, begun in 447 BCE and dedicated in 438 BCE, would remain the great city's symbol for a thousand years until, in Late Antiquity, it disappeared from the historical record, possibly taken to Constantinople and there later destroyed.
