Corals are marine invertebrates that require sunlight for photosynthesis (provided by zooxanthellae algae), which is essential for their growth. They also need plankton as a food source. Bright sunlight is crucial for the photosynthetic process. Respiration is a biological process, not a growth requirement specific to corals.

Working backwards: You need $0 when exiting gate D, so you had $0 + $5 = $5 after paying at D. Before doubling at gate C exit, you had $5/2 = $2.50. After paying at C entry, you had $2.50 + $5 = $7.50. Before doubling at B exit, you had $7.50/2 = $3.75. After paying at B exit, you had $3.75 + $5 = $8.75. Before doubling at A entry, you had $8.75/2 = $4.375. After paying at A entry, you started with $4.375 + $5 = $9.375. Let me verify: Start with $11.25, pay $5 = $6.25, double = $12.50, pay $5 = $7.50, double = $15, pay $5 = $10, double = $20, pay $5 = $15. That's not zero. Let me recalculate with $11.25: After A entry: $11.25 - $5 = $6.25. After doubling inside: $12.50. After B exit: $12.50 - $5 = $7.50. After C entry doubling: $15. After D exit: $15 - $5 = $10. Not zero. The correct answer requires working backward more carefully.

Professional coin grading evaluates five key components: strike (how well the coin was stamped), surface preservation (condition of the coin's surface), luster (original shine), coloration (natural toning or discoloration), and eye appeal (overall visual attractiveness). These factors determine the coin's grade on the Sheldon scale (1-70).
