<p>1.) How might you add "Keystone species" to the concept map?&nbsp;</p> <p><em>A.) Keystone species</em>&nbsp;increase competition among all&nbsp;populations in a&nbsp;<em>community. &nbsp;</em>&nbsp;</p> <p><em>B.) Keystone species</em>&nbsp;are the most abundant members of&nbsp;<em>communities</em>.</p> <p><em>C.) Keystone species</em>&nbsp;always live with other species in&nbsp;<em>symbiosis</em>.</p> <p><em>D.) Keystone species</em>&nbsp;influence the diversity of&nbsp;<em>communities</em>.&nbsp;</p> <p>2.) What is the correct relationship between the abiotic environment and&nbsp;trophic levels? (Select all that apply.)</p> <p>The resources available in the abiotic environment limit the&nbsp;number of trophic levels in a community.</p> <p>Fat soluble chemicals that organisms at low trophic levels obtain from the abiotic environment will decrease in concentration&nbsp;in the higher trophic levels.</p> <p>Organisms at the lowest trophic level of a community&nbsp;obtain nutrients directly from&nbsp;the abiotic environment.</p> <p>Some of the energy that producers obtain from the abiotic environment is lost at each trophic level.&nbsp;</p> <p>3.) Herbivory has the same effect on species in a community as&nbsp;</p> <p>competition.</p> <p>mutualism.</p> <p>commensalism.</p> <p>parasitism.</p> <p>&nbsp;</p>

Lab Report: 14 Bacteriophage Specificity 1. What was the purpose of this exercise? 2. Complete the following table with your observations: Lysis (yes/no) Name of the bacterium S. Aureus (+) Yes Yes E. Coli (-) No Ent. Aerogenes (-) 3. How do you know if bacteriophage infected the bacteria? You can see a plaque. 4. Why didn't the bacteriophage infect all three bacteria? flest Cell specificity What is the explanation for bacteriophage specificity when it comes to infecting specific bacterium? wiceptors
