Refer to the Figure Showing Acclimatization to Two Different Growth

question 24

Multiple Choice

Refer to the figure showing acclimatization to two different growth temperature regimes from different populations of a shrub occurring in the Mojave Desert and in cool coastal zones in California. The two temperatures regimes used are representative of the two habitats.
Of the four temperature curves in the two populations, which combination appears least able to acclimate to the given temperature regime?

• A) Desert population at the 23°C day/18°C night regime
• B) Desert population at the 43°C day/30°C night regime
• C) Coastal population at the 23°C day/18°C night regime
• D) Coastal population at the 43°C day/30°C night regime

Definitions:

Hydrogen Bond

A feeble attachment formed between two molecules due to the electrostatic pull between a proton in one molecule and an atom with a high affinity for electrons in the other.

Covalent Bond

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons, strongly binding them together in a molecule.

Polysaccharides

Large molecules composed of long chains of monosaccharide units bonded together, serving various functions such as storage and structural roles in plants and animals.

Triacylglycerols

Lipids formed by three fatty acids linked to a glycerol molecule; a main form of energy storage in animals.
