which individually or as an associated complex take on a three-dimensional shape. When properly associated‚ these shapes form the active site and other supporting structures that allow enzymes to be effective catalysts (Nelson and Cox 2005). Temperature represents the average kinetic energy in an object or solution (Russell and others 2010). This energy causes rapid movement of dissolved particles‚ such as enzymes and substrate molecules‚ increasing the chances that they’ll contact each other in

Tundra Climate (E) The tundra is a bleak and treeless place. It is cold through all months of the year Summer is a brief period of milder climates when the sun shines almost 24 hours a day. It has been called "the land of the midnight sun". But even the sun can’t warm the tundra much. The short summer lasts only 6 to 10 weeks. It never gets any warmer than 45 or 50° F. The warmer weather causes a layer of permafrost‚ ice that never goes away in the ground‚ to melt‚ creating bogs and shallow lakes

average temperature in the coniferous forest is below freezing? In the coniferous forest‚ winter and summer are the two main seasons. Spring and autumn are so short that it is hard to know if they exist. Winters are extremely long‚ freezing and dry. Winter lasts about five to seven months. It snows often‚ and the average temperature is 14°C. The temperature is -54°C to -1°C in winter. Summers are short‚ humid‚ warm and rainy. It is about fifty to one hundred frost-free days. The temperature is -7°C

BIOMES LAB BIOL 120 `` A biome is a major complex of similar communities. It is the largest ecological unit we recognize. Different books vary in the number of biomes they list. Temperature and precipitation are the two key factors that determine the different type biomes. Some books consider marine ecosystems and freshwater systems as biomes. Others break out wetlands as a biome. We will look at 10 terrestrial biomes: 1. Tundra (Arctic and alpine) 2. Boreal forest or taiga

grassland biome is characterized by a prolonged dry season. _F__ 2. The taiga biome is found in North America‚ Asia‚ and Africa. __F_ 3. In the desert biome‚ the rate of precipitation exceeds the rate of evaporation. __F_ 4. The taiga and a plant cell are both examples of closed systems. __T_ 5. If the climate changes‚ the species that are best adapted to the new conditions are most likely to survive. Matching Match each description in column A with the correct biome in column
