Moist air from the south moves up the Himalayas in Asia, falling as rain on the mountain slopes. The north and northwest regions of China, on the leeward side of the mountains, are very dry. These regions include Mongolia’s Gobi Desert.  The dry conditions on the leeward side of the Himalayas result from a topographical feature known as a:

• topographic shift

• rain shadow

• heat dome

• temperature inversion

What pattern of dispersion is depicted in the picture?

• random

• clumped

• linear

• uniform

A population of Zebras in Northern Kenya had 583 members of its zeal (group) at the beginning of 2017. During the year 97 foals were born and 17 died. Over the course of the year, 7 new zebras immigrated to the existing population and 11 emigrated. At the beginning of 2018, how many would be expected to be within the zeal?

Which of the following is a density-independent factor

• Food supply

• Pathogens

• Cold spell

• Predators

What type of survivorship curve would you expect this organism to have?

• Type I

• Type II

• Type III

Where the rivers meet the sea, creating variability in salinity, sediment, and light conditions.

• Estuary

• Benthic Zone

• Intertidal Zone

• Photic Zone

This biome supports large herds of grazing animals, has an average annual temperature of 9.1°C and a total annual precipitation of 727mm.
