How long should a tail be for a swimming organism?

The video tutorial explores the design of an ideal swimming microorganism, focusing on the optimal head-to-tail ratio. It explains that a tail should be 12 times the length of the head for efficient swimming, regardless of the environment or organism. This ratio is validated by examining 400 microorganisms, showing that biology naturally follows this principle. The tutorial concludes with applications in designing microtransporters, emphasizing the importance of this ratio for efficiency.

What is the primary function of the tail in a swimming microorganism?

• To serve as a motor for movement

• To store genetic information

• To protect the head

• To act as a sensory organ

What is the optimal size ratio of head to tail for a swimming microorganism?

• 15

• 12

• 10

• 8

Why is the ratio of 12 significant in the design of swimming microorganisms?

• It is universally optimal across different conditions

• It minimizes energy consumption

• It maximizes speed

• It is the easiest to construct

How many microorganisms did Daniel study to confirm the optimal ratio?

• 400

• 100

• 200

• 300

What lesson can be learned from the biological evidence regarding the ratio of 12?

• The ratio is only applicable to certain species

• Microorganisms are inefficient swimmers

• Evolution has optimized organisms to exploit physics

• Biology often ignores physical laws
