W: Hi, Dan, you know that lab you missed? You can have my notes.
M: Thanks. I appreciate that.
W: So how are you feeling?
M: Much better now that I began taking an antibiotic. Student health gave me one, and it's really help. You know what mazes me that the human races survive before antibiotics.
W: I agree. When my father was a young boy in the 1940's, he got blood poisoning and would have died. But his doctor had heard of this new drug, called penicillin.
M: Wow, he was really lucky. And now we have lots of antibiotics that kill bacteria.
W: Well, penicillin kills bacteria, but not all antibiotics do. So are just slowing the bacteria down until our normal immune defenses can finish the job. Tetracycline works that way.
M: Wow, you are a fund of drug trivia. How do you know all these?
W: My mother used to look up all our medicines, prescription and non-prescription. There are lots of books around. It's interesting. What antibiotic are you taking?
M: I don't remember. It's on the bottle. I think I'll take a new look at the label and drop by the library to see if they have reference books on medicines. See you in lab tomorrow.

W: Hi, Bill, how is it going?
M: Oh, hi, Jan. I'm OK. How about you?
W: You can probably tell just by looking at me. I'm really busy. Hey, what are you reading?
M: A pretty interesting article. My biology professor assigned it, and I thought I just look it over. But I got really involved in it. It's about endangered species.
W: That sounds pretty interesting. I'm getting frustrated with the two research papers I'm struggling with.
M: Oh?
W: And can you believe they are both due on the same day?
M: That's tough.
W: I'll get through it. So what's this you are reading?
M: Well, it's basically about the choices conservationists are faced with. You know, these days when funding so hard to come by.
W: Wait a minute. Is the focus on biology or economies?
M: Both. Conservationists don't have enough funding to save every endangered species in the world, so they have to decide based on what would be lost if a species became extinct.
W: Can you give me an example of what you mean?
M: Take for instance, two animals, the spotted awl and the tailed toad. The article says the toad is unique. It has no relatives. But there are a lot of varieties of awls.
W: So, if that toad became extinct, we'd lose an important link in the chain of revolution, right?
M: Exactly. But that isn't so for the awl. So for conservationists, it might be clear choice of which animal to save.
W: I see. I am glad I don't have to make that kind of decision. Aren't you?
