In the 1950s, Stanley Miller and Harold Urey designed experiments that tested Alexander Oparin's and J.B.S. Haldane's hypothesis

that conditions on the primitive Earth favored chemical reactions that synthesized more complex organic compounds from simpler organic precursors. Miller and Urey used an apparatus that recreated the conditions of what a primitive Earth was thought to consist of at the time. Methane, hydrogen, ammonia, and steam were all included to recreate conditions similar to that of a primitive Earth. Their goal was to create complex organic molecules from the simple organic molecules that were believed to be part of primitive Earth's makeup. The Miller-Urey experiment was run for a week and the samples collected were analyzed. Analysis showed that some of the carbon in the apparatus was converted to amino acids molecules. In later experiments, similar to Miller and Urey's, it has been shown that it is possible to form all 20 amino acids commonly found in organisms. Along with nucleic acids, other molecules were detected in samples. Some of these were sugars, lipids, adenine, and even ATP in certain conditions.
Based on the information in The Miller-Urey Experiment reading passage above, which of the following statements is most accurate?

The most important adaptive advantage associated with the filamentous nature of fungal mycelia is
MAVERICK [17]

Answer:

d. an extensive surface area well suited for invasive growth and absorptive nutrition.

Explanation:

Fungi have an extracellular nutrition. These means enzymes are released to environment to start degrading macromolecules which can be later be absorbed (absorptive nutrition) through cell membranes. Having multiple spots (bigger surface area) through which it can nurture speeds up the rate at which it can grow leading to a faster growth and higher competition over resources.
