Animal Form
and Function
and Function
A system of negative feedback to regulate change in internal conditions.
What is homeostasis?
The pressure of a particular gas in
a mixture of gases.
What is partial pressure?
This occurs when stomata are open and the air surrounding leaves is drier than the air inside leaves.
What is transpiration?
Algae blooms due to excess fertilizer runoff.
What is eutrophication?
This gene and protein is found to play a role in the development of the notochord and floor plates in vertebrates (Cohn and Tickle 1999).
What is sonic hedgehog?
These animals have higher metabolic rates and thus can be more active.
What is an endotherm?
The valve between the left ventricle and the aorta.
What is the mitral valve?
The tendency of water to move in response to
differences in solute concentration.
What is solute potential?
The scarcity of these three macronutrients is reflected in the deterioration of older leaves.
What are N, P, and K?
How sap moves in the phloem.
What is the pressure flow hypothesis?
Small thermostable, hydrophobic proteins that
bind to larger proteins and assist their folding
into functional conformations or prevent
disfunctional conformations.
What are heat shock proteins?
The way fluid moves on the arteriole side of the capillaries where pressure is higher inside the capillaries than out.
What is out of the capillaries?
How water is pulled up to the tops of trees along a water-potential gradient, via forces generated
by transpiration at leaf surfaces.
What is cohesion-tension theory?
The process with which plants release H+ into the soil to absorb nutrients such as Na+, K+, and Ca2+.
What is cation exchange?
What is gravimetric potential?
This membrane protein senses changes in temperature to manage thermoregulation at the cellular level.
What are temperature sensitive ion channels?
The binding of each successive oxygen molecule to a subunit of the hemoglobin molecule that causes a conformational change in the protein, making the remaining subunits much more likely to bind oxygen.
The enzyme that C4 plants use to bind CO2 to move into the bundle sheath cells.
What is PEP carboxylase?
The availability of these macronutrients is greatly reduced by acid rain.
What are cations?
As net surface charge increases, the maximum myoglobin concentration changes in this way (Mirceta et al. 2013).
What is increase?
What is the reason that smaller animals need to eat more per body mass?
What is surface area:volume ratio
A phenomenon that makes hemoglobin more likely
to release oxygen during exercise or other conditions in which Pco2 is high, pH is low, and tissues are under oxygen stress.
What is the Bohr shift?
The overall water potential in a xylem cell with a pressure potential of -1.0
MPa, a solute potential of -0.1 MPa, and a gravimetric potential of -0.2 MPa.
What is -1.3 MPa?
This membrane protein brings H+ atoms back into the plant and allows anions to "hitchhike" into the roots for absorption.
What is a symporter/cotransporter?
What is Emilio Estevez?
