Off the Monterey Bay coast in California there is a kelp forest. The kelp grows talls and sways in a sea full of sunshine. It
provides a protective habitat for many maturing species. The kelp is consumed by sea urchins which are consumed by sea otters. Over fishing in the ocean reduced the food for killer whales so they came close to the coast to prey on the sea otters. The drop in sea otters caused a rise in sea urchins which greatly reduced the kelp.

In this ecosystem, the _______

4) A hypothetical bacterium swims among human intestinal contents until it finds a
suitable location on the intestinal lining. It adheres to the intestinal lining using a feature
that also protects it from phagocytes, bacteriophages, and dehydration. Fecal matter from
a human in whose intestine this bacterium lives can spread the bacterium, even after
being mixed with water and boiled. The bacterium is not susceptible to the penicillin
family of antibiotics. It contains no plasmids and relatively little peptidoglycan. The cell
also lacks F factors and F plasmids. Which of the following statements about the bacteria
is most probably accurate?
A) The bacterium cannot donate DNA through conjugation with another cell.
B) The bacterium cannot take up DNA from its external environment.
C) The bacterium cannot form an endospore.
D) The bacterium cannot reproduce.

Clues to ecological principles are given in numerous passages of the Bible. A Bible study of ecology actually opens the doors to better understanding of God's love and concern for the earth. Use a concordance to locate Bible passages associated with words concerning our stewardship of the earth. You may use a dictionary to find synonyms for these words: dominion replenish subdue judgment stewardship Find each of the passages using these words related to principles of ecology. List all passages by quote, book, chapter, and verse under each word. Use your own interpretation to rewrite what you think each verse is saying. After your discussion of each of these words, ask one other person to explain his understanding of the word and a related verse without any hints. Summarize what he tells you. A concluding paragraph for each of the words should be written noting similarities and differences between your interpretation and that of each person consulted.

A vaccine is a substance that contains all or part of a noninfectious version of a disease-causing organism. When the vaccine is administered to a person, the person's immune system attacks the noninfectious version of the organism and learns to recognize its surface proteins. The next time the immune system comes in contact with the same surface proteins, it has a defense already prepared in order to respond quickly to the invading organism. In this way, a vaccine gives people immunity to the disease-causing organism.

Vaccines can be life-saving, but there have been a few cases of people catching a disease from the administered vaccine.
