Question

what process is shown?respirationactive transportdiffusionosmosis2 multiple choice 2 pointsmichael is designing a dna model for class. which shape should he design his dna to accurately model the structure?double helixrectanglestraightcircle

Explanation:

1. For the first question: The diagram shows particles moving from an area of higher concentration to lower concentration until evenly distributed, which matches the definition of diffusion. Respiration is energy production, active transport requires energy to move particles against a gradient, and osmosis is only the movement of water across a semipermeable membrane.
2. For the second question: The confirmed, accurate structure of DNA is a double helix, which is the standard scientific model for DNA's shape. The other options do not match DNA's actual structure.

Answer:

1. Diffusion
2. double helix
