Often, sidewalks that are 8 ft wide have a 4 ft wide ramp where they transition to a crosswalk. Explain why this is either consistent or inconsistent with the principle of universal design.
Homework Answers
It is consistent with the universal design. It is done so the differently abled people can climb up the sidewalk from crosswalk and use it. This is the reason ramp is provided at that intersection

Illustrate all the locations where the molecule 8-ethyl deca-2, 4 diene could form hydrogen bonds with water either as a hydrogen donor or as a target (receiver) of hydrogen bonds from water. Do this by drawing bent water molecules as necessary and representing hydrogen bonds between water and the molecule using dashed lines. Be sure it is clear exactly which atoms on each molecule are involved in the hydrogen bonds. If the molecule is not capable of forming hydrogen bonds...

You are considering buying some new windows for your house, where you have single paned glass windows where the glass is 1/8 " thick. You normally like to keep your house at 75 oF, even when the outside temperature is 105 oF in Tucson, AZ. You are planning on replacing a window that is 3 feet tall and 18 inches wide in your bathroom with double paned glass that is the same thickness glass on each side, but that has...

1. What is often true about the relative rates of phenotypic evolution of sexually selected traits vs most other kinds of traits? 2. In the good genes model, why does a male trait have to be costly in order for the female preference to be maintained by natural selection? 3. Explain the Fisherian (runaway)model of sexual selection –what generates correlations between female preferences and male traits. What kind of experimental observation would support the model? 4. Explain the concept of...
