Question
Chapter 42.2, Problem 1CS
Summary Introduction
To determine: The biological functions of ion
Introduction: The electrochemical gradient is the electrocemical potential across a membrane. It consists of both chemical and electrical components. The electrical gradient is the difference in concentration of ions across the membrane whereas the chemical gradient is the difference in concentration of solute across the membrane.

Data vs. information: What is the short answer to this question?
Instruction: Propose a hypothesis for the given scenario below. Please answer here directly. Also, support your answer with scientific bases. Female silkworm moths (Bombyx mori) attract males by emitting chemical signals that spread through the air. A male hundreds of meters away can detect these molecules and fly toward their source. The sensory organs responsible for this behavior are the comb like antennae visible in the photograph shown here. Each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. Based on what you learned in this chapter, propose a hypothesis to account for the ability of the male moth to detect a specific molecule in the presence of many other molecules in the air. What predictions does your hypothesis make?
In a study published in Science, Premack and Woodruff asked: "To what extent does the chimpanzee comprehend the elements of a problem situation and potential solutions?" An adult chimpanzee (Sarah) was shown 30-second videotapes of a human actor struggling with one of several problems (for example, not able to reach bananas hanging from the ceiling, a record player not playing). Then Sarah was shown two photographs, one that depicted a solution to the problem (like stepping onto a box, plugging in the record player) and one that did not. She was then instructed to pick one of the photos and place it under the television monitor. (Sarah had been raised in captivity since age one and had extensive prior exposure to photographs and television.) The order in which the scenes were presented to Sarah was randomized, as was the left/right position of the photos presented to her. Sarah was shown eight different scenarios. For each scenario, researchers recorded whether Sarah selected the…
