In chickens, the frizzle gene “F” controls the appearance of the feathers. A homozygous dominant chicken for the frizzle gene shows “extreme frizzle”, that is his feathers are extremely disrupted. The normal chicken is homozygous recessive and has undisrupted feathers. When a chicken with extreme frizzle is mated with a normal chicken, all of the offspring exhibit mild frizzle.

B) Specialized organelles that perform specific functions, such as protein synthesis, directed by the nucleus. C) A cell membrane that supports structure and maintains rigidity (Note: Not all eukaryotes have a cell wall; it is primarily found in plant cells and fungi).

Ciproflaxin is a broad spectrum antibiotic that kills most normal microbial inhabitants in the human gut. Clostridium difficile is found in small numbers in the normal flora of some healthy adults however this normal inhabitant of the gut is not affected by ciproflaxin. Clostridium difficile is innately resistant to ciproflaxin. After therapy with ciproflaxin patients who normally carry Clostridium difficile often exhibit Clostridium difficile-associated diarrhea. The change in ability of Clostridium difficile to cause disease would best be explained by the statement that [choose the statement below that you would argue is the best explanation] a. Ciproflaxin interacted with Clostridium difficile in a manner to make the organism more pathogenic. b. I do not know the answer to this question. c. Ciproflaxin has killed the microbes that normally compete with Clostridium difficile in the gut allowing the microbe to grow uncontrolled. d. Ciproflaxin acted as a mutagen. Ciproflaxin induced a mutation in Clostridium difficile to make the organism more pathogenic.
