True/False Indicate whether the statement is true or false. ____ 81. Mutations are sometimes beneficial. ____ 82. Selective breeding is a method of artificial selection. ____ 83. When local environmental conditions change, species may become extinct through background extinction. ____ 84. Natural Selection relies on three truths, one of which is based on genetic mutations. ____ 85. Extinction is the permanent loss of genetic diversity. ____ 86. Mutations must occur for biological evolution to happen. ____ 87. Geographic isolation and reproductive isolation are the two processes that affect the number and types of species on earth. ____ 88. Deciduous forests are typically located at higher altitudes than coniferous forests. ____ 89. The concentration of greenhouse gases and the average temperature of the atmosphere have an inverse relationship. ____ 90. Tundras are generally colder than chaparrals. ____ 91. The rainshadow effect explains why the leeward side of a mountain range will have semiarid and arid conditions. ____ 92. Jack rabbits, diamondback rattlesnakes, collared lizards, and prickly pear cacti are biotic components tropical deserts. ____ 93. Driving cars, using fossil fuels for electricity, and deforestation all lead to an increase in dioxide in the atmosphere. ____ 94. Biomes are affected by ocean currents and water flow. ____ 95. The two types of aquatic life zones on earth are freshwater life zones and coastal life zones. ____ 96. The euphotic zone is that region of the ocean just below the limit of light absorption. ____ 97. Algae flourish most abundantly in the bathyal zone on the ocean. ____ 98. Water in the floodplain zone is generally warmer and slower than water in the transition zone. ____ 99. A lake's profundal zone has less oxygen than it's littoral zone. ____ 100. Lotic bodies of freshwater, such as lakes and ponds, have less oxygen in the euphotic zone than do lentic bodies.
101. ____________________ have no leaves and can store water and synthesize food in their tissue in order to survive in very dry climates. 102. ____________________ is the main reason tundras form many shallow lakes and ponds, as well as keeping methane gas locked in the soil. 103. ____________________ are essential portions of watersheds because they serve as the liaison between land and water resources. 104. Aquatic plants would most likely not be found in a(an) ____________________ because of the light depravation. 105. ____________________ is determined by environmental factors including temperature, sunlight, dissolved oxygen, and available nutrients. 106. Most people would probably prefer swimming in a(an) ____________________ lake because they are clear and very little aquatic life. 107. The ____________________ in marine systems in the most susceptible to human interference. 108. The ____________________ in marine systems has the highest productivity per unit area, primarily because of nutrients and sunlight. 109. Aquatic life zones such as streams and rivers are also called ____________________. 110. Organisms living in the ____________________ must have adaptations to survive the impact of waves and live in both dry and wet conditions. Matching
