Chapter 35, Problem 2TYK
What important role does the Casparian strip play in the movementof water through plants?
a. forces water to move through the cytoplasm of living endodermal cells as it makes its way from the soil to the xylem
b. causes cells to shrink, thereby increasing pressure within cells
c. loads sugars into xylem, thereby causing water to enter the xylem by osmosis
d. acts as a filter that prevents salts, heavy metals, and other pollutants from entering root hairs

Under normal conditions, this protein is confined to a particular region of the membrane due to the cortical actin cytoskeletal network. Which of the following changes is most likely to increase mobility of this protein beyond the normal restricted region of the membrane? A. Increased temperature B.

How does your team wish to delineate the domain or scale in which these objects or events operate? How does that limited domain facilitate a more feasible research project? What is your understanding of their relationships to other objects and events? Are you excluding other things from consideration which may influence the phenomena you seek to understand? Examples of such exclusions might include certain air-born pollutants; a general class of water bodies near Ottawa, or measurements recorded at other months of the year; interview participants from other organizations that are involved in the development of your central topic or issue. In what ways do your research questions follow as the most appropriate and/or most practical questions (given the circumstances) to pursue to better understand…arrow_forward
- The Esp gene encodes a protein that alters the structure of the insulin receptor on osteoblasts and interferes with the binding of insulin to the receptor. A researcher created a group of osteoblasts with an Esp mutation that prevented the production of a functional Esp product (mutant). The researcher then exposed the mutant strain and a normal strain that expresses Esp to glucose and compared the levels of insulin in the blood near the osteoblasts (Figure 2). Which of the following claims is most consistent with the data shown in Figure 2 ? A Esp expression is necessary to prevent the overproduction of insulin.

In the tomato, red fruit (O+) is dominant over orange fruit (0), and yellow flowers (W+) are dominant over white flowers (w). A cross was made between true-breeding plants with red fruit and yellow flowers, and plants with orange fruit and white flowers. The F₁ plants were then crossed to plants with orange fruit and white flowers, which produced the following results: a. b. 333 red fruit, yellow flowers 64 red fruit, white flowers 58 orange fruit, yellow flowers 350 orange fruit, white flowers Conduct a chi-square analysis to demonstrate that these two genes DO NOT assort independently.
