Biology for Engineers: Unit 1 Quiz

Shinkansen Bullet Train Redesign

• The redesigned nose of the Shinkansen bullet train was inspired by the kingfisher bird. Its streamlined shape allows for reduced air resistance and noise when traveling at high speeds.

Passive Cooling in Skyscrapers

• Passive cooling techniques in skyscrapers are inspired by natural ventilation systems found in termitaries, the mounds constructed by termites. These structures maintain a stable internal temperature despite extreme external conditions.

Genetically Modified Corn

• The gene used to develop genetically modified corn is the Bacillus thuringiensis (Bt) gene. This gene allows the corn to produce a protein toxic to certain pests, enhancing crop protection and yield.

Retinal Prosthetic Approval

• The retinal prosthetic developed by scientists has been approved by the Food and Drug Administration (FDA). This device is designed to restore partial vision for people suffering from certain types of blindness.

Nanoparticle Size Range

• Nanoparticles typically range from 1 to 100 nanometers in size. This scale allows them to exhibit unique physical and chemical properties advantageous for various applications, including medicine and electronics.
