A gram-positive Bacillus, which is c-hemolytic on 5% sheep blood agar, produces a wide zone of lecithinase on egg yolk agar, is nonmotile, and was isolated from the stool of a patient with abdominal pain and watery diarrhea. Because of the patient's existing immunocompromised state, the physician administered penicillin as the antibiotic therapy. The patient's condition did not improve after 7
days of treatment. Which one of the following statements explains the reason for the antibiotic failure? a. The course was too abbreviated and should be given for 14 days. b. The patient may be allergic to penicillin and its therapeutic effects. c. Penicillin is ineffective against gram-positive organisms. d. The organism produces c-lactamase, which renders the drug inactive.

Plants require energy to perform photosynthesis. Photosynthesis uses the energy, water, and carbon dioxide to make glucose, which is stored for energy. Because energy is initially required, photosynthesis is a(n) reaction.
This diagram summarizes energy transfers and molecule exchanges among plants and animals, as you will later learn we call producers and consumers.
