Exercise 1.2 introduced a study exploring the effect of
antibiotic treatment for acute sinusitis. Study
participants either received either a 10-day course of an
antibiotic
(treatment) or a placebo similar in appearance and taste (control). At the end
of the 10-day period, patients were asked if they experienced an
improvement in symptoms. What are the explanatory and response variables
in this study?

3. SC.912.L.14.7 An apple tree is an example of a fruiting plant. A cross-section of the apple is shown below. a. From what part of the apple does structure A develop and what is its primary function? It develops from the guard cells and its primary function is glucose storage. b. It develops from the ground tissue and its primary function is glucose storage. c. It develops from the seeds of the tree and its primary function is for reproduction. d. It develops from the flower of the tree and its primary function is for reproduction. 4. SC.912.L.14.7 Terrestrial plants have stomata on the surface of their leaves. A single stoma is surrounded by two guard cells that change shape to open or close the stoma in response to environmental factors. Which of the following best explains how the structure of the leaf is used in processes that occur in plants? a. Water enters the plant through the surface of the leaf for transpiration. b. Gases for photosynthesis are exchanged through the surface of the leaf. c. Energy for cellular reproduction is absorbed through the surface of the leaf. d. Carbon dioxide enters the plant through the surface of the leaf for cellular reproduction. 5. SC.912.L.14.7 Specialized cells often have a unique size and shape that allow them to perform a specific function in the organism. Cells of the same type are usually organized into tissues that in turn form organs. A given organ may have several different tissues and thus several specialized cell types. Which of the following tissues are matched to the correct physiological function? Ground tissues are specialized for transpiration. b. Meristematic tissues are specialized for growth. c. Dermal tissues are specialized for photosynthesis. d. Vascular tissue are specialized in reproduction. a.
