The answer is the second one: a chain-link fence.

Explanation for each option:

  1. A rain coat: This option is incorrect because a raincoat is designed to be impermeable to water, providing a barrier that prevents water from passing through. The peptidoglycan cell wall of bacteria, while providing structural support, is not impermeable and allows certain substances to pass through.

  2. A chain-link fence: This option is correct. A chain-link fence provides structural support and protection while still allowing the passage of small objects and substances. Similarly, the peptidoglycan cell wall of bacteria provides structural integrity and shape to the cell while allowing the passage of nutrients, waste products, and other small molecules.

  3. A sugary candy shell: This option is incorrect because a sugary candy shell is typically a solid, impermeable layer that encases something completely. The peptidoglycan cell wall is not a solid, impermeable layer; it is a mesh-like structure that allows the passage of certain substances.

  4. An impenetrable brick wall: This option is incorrect because an impenetrable brick wall suggests a solid, non-permeable barrier that nothing can pass through. The peptidoglycan cell wall, while providing rigidity and protection, is not impenetrable and allows the passage of small molecules.

Summary: The peptidoglycan cell wall of bacteria is most analogous to a chain-link fence because it provides structural support and protection while allowing the passage of certain substances.

1920s and 1930s, Hawthorne Works was the site of some well-known industrial studies. In one of the studies, researchers investigated the impact of different working conditions on worker productivity. Prior to the start of the study, researchers secretly measured workers' productivity for several weeks. Then researchers chose two workers, who then chose their own teams. The teams were separated from the general workforce and completed their work in different experiment rooms where the researchers could observe them more easily. Over a 5-year period researchers manipulated the structure of the workday for each team (number and duration of breaks and number of hours per shift). For each of these changes in working conditions, the researchers measured the effect on productivity. For some conditions, such as frequent short breaks, workers rebelled by intentionally decreasing productivity. Why did the researchers secretly measure the workers' productivity before creating the two treatment groups? To create similar treatment groups so that a cause-and-effect relationship could be established To provide a baseline for measuring worker productivity To directly control for confounding variables
