Fish poop.

Tropical white beaches get their pearly white color from the excrement of fish far off of the coast which eat coral and other things that reside on the ocean floor. When they eat they swallow some sand into their mouths as well, and process it with the food they just ate. Their stomachs can't really digest the sand, tiny minute rocks essentially, and thus turn their color white. Or the rock forming the sand can be naturally pigmented a whitish tone as well.

Motor (efferent) neurons carry information _____ the brain whereas sensory (afferent) neurons carry information ______ the brain

Norma-Jean [14]

Neurons are the building blocks of the nervous system. They are the links so that information could be processed as electrochemical signals. There are three fundamental kinds of neurons in our body:

1. Motor neurons - they carry signals from the central nervous system (CNS) to the body parts such as muscle movement
2. Sensory neurons - they carry signals from other body parts to the CNS
3. Interneurons - interlinking neurons between the brain and the spinal cord

Thus, the correct and complete statement above should be

Motor (efferent) neurons carry information from the brain whereas sensory (afferent) neurons carry information to the brain.
