6. Concerning the Australian climate, which of the following general statements is untrue:
a. Annual rainfall generally decreases from the coasts to the interior.
b. Summer rainfall predominates in the north of the continent, and winter rainfall
in the south.
c. In the arid zone there is little variability in rainfall, from month to month or year
to year.
d. Potential evapotranspiration (PET) increases towards the equator, driven by
trends in temperature and solar radiation.
7. Cluster roots predominantly facilitate more effective uptake of which key nutrient?
a. Molybdenum
b. Nitrogen
c. Phosphorus
d. Potassium
8. Sclerophylly refers to:
a. A large swelling formed at the base of the stem of many plants
b. The characteristic of having a hard leaf
c. The characteristic of having a hard, woody fruit
d. The characteristic of having a soft, fleshy leaf
9. Photosynthetic nitrogen-use efficiency is a measure that defines:
a. How often N-rich fertilizer should be applied
b. The cost of measuring photosynthetic nitrogen use
c. The half-life (rate of turnover) of photosynthetic proteins
d. The ratio of the rate of photosynthesis to leaf N concentration
10. In seedling growth analysis what are common units for relative growth rate, RGR?
a. Area per mass
b. Area per mass per day
c. Mass per area per day
d. Mass per mass per day
Explanation / Answer
6.Correct answer is: :In the arid zone there is little variability in rainfall, from month to month or year
to year.
Reason:In arid zone,little rainfalls occur during the hottest months i.e from October to March.
7.Correct answer is:c.Phosphorus
Reason:Cluster roots participate in phosphorus intake.
8.Correct answer is:b. The characteristic of having a hard leaf.
Reason:Sclerophylly refers to hard,stiff or tough leaves.
9.Correct answer is:d.The ratio of the rate of photosynthesis to leaf N concentration
Reason:How musch Nitrogen is assimilated is known via photosynthetic nitrogen use efficacy.
10.Correct answer is:c.Mass per area per day
Reason:mass per are per day would best define relative growth rate in seedlings.
