Environmental resistance may limit the size of populations by 1. increasing both birth and death rates. 2. decreasing both birth and death rates. 3. increasing death rates and/or decreasing birth rates. 4. decreasing death rates and/or increasing birth rates. 5. changing the biotic potential. 3. In the cohesion-tension theory the tension part refers to 1. the tendency of water molecules to be attracted to minerals in the water. 2. the process of osmosis that pulls water into the root. 3. the evaporation of water from the stomata of the leaf. 4. the use of water in photosynthesis resulting in a shortage of water in the leaf. 5. the attraction of water molecules for each other. 4. The biotic potential of a population 1. directly affects environmental resistance. 2. causes changes in birth rates without affecting death rates. 3. causes changes in death rates without affecting birth rates. 4. is the maximum rate at which a population may increase. 5. both 1 and 3 5. Exponential growth occurs when 1. there is a constant number of births each year and b > d. 2. the population grows by a fixed percentage each year. 3. immigration is greater than emigration. 4. the biotic potential increases each year. 5. environmental resistance declines each year. 6.
