Question 1 of 13
1. Question
DNA’s minimalism refers to the fact that DNA engineers the bone structures of animals and humans so they are the minimal size and minimal amount needed for that creature. The fact that birds like a hummingbird can fly, or a dolphin jump can jump 22 feet, or an Olympian perform gymnastics without breaking their bones shows that DNA engineered bones are engineered correctly for each stage of life for living things. (This is tricky. You have to deduce things and look carefully at every detail. It will be this way in many of the questions all through these gold digs.)

Question 13 of 13
13. Question
A real problem with being in Space for any extended period of time is that your bones begin to diminish in width and mass because of the lack of stress on them. Because of this, astronauts visiting the ISS exercise almost every day. (Different bears don’t have this problem. They can hibernate for 5 months at a time and not lose any bone density at all. )
