The lens is one of the few tissues in the human body that continues to grow throughout life. As we age, the lens becomes thicker and less flexible, which is why older adults often have difficulty focusing on near objects (a condition called presbyopia).

Despite its name, the large intestine is much shorter than the small intestine. The small intestine is approximately 20 feet long, while the large intestine is only about 5 feet in length. The term large refers to its diameter, not its length.

Unlike most tissues that stop growing after adolescence, cartilage continues to grow throughout life. This is why ears and noses appear larger in older adults - the cartilage keeps growing while other tissues have stopped.

Despite representing only about 2% of body weight, the brain consumes approximately 20% of the body's total oxygen supply. This high demand reflects the brain's intense metabolic activity and its constant need for energy to maintain neural function.

The stapes is the smallest bone in the human body, measuring approximately 3-4 millimeters. It is located in the middle ear, where it transmits sound vibrations from the incus to the inner ear. No bones are found in the human nose.

The human brain is approximately 80% water, which is essential for its proper function and shock absorption. While the brain reaches about 90% of its adult size by age 6, it completes most structural development by early adulthood (around age 18-25), though neural plasticity continues throughout life.

Each human foot contains 26 bones, for a total of 52 bones in both feet. Since the adult human body has 206 bones, the feet contain approximately 25% of all bones - exactly one-quarter, making this statement accurate.

In microgravity, the vertebral discs expand because they're not compressed by Earth's gravity. This can increase an astronaut's height by 1-2 inches. The effect is temporary - they return to normal height within days back on Earth as gravity recompresses the spine.

The answer is 10 because Java uses short-circuit evaluation for the && operator. Since y > 10 is false (y equals 10), the second condition (x++ > 10) is never evaluated, so the increment x++ doesn't execute. This means x remains 10. Option C (11) would only occur if the increment executed, and options A and D are nonsensical in this context.
