Definition: A type of mineral that is mostly made of manganese carbonate, known for its light pink to rose-red color and shiny surface, often used as a source of manganese.

Example: The geologist collected a sample of rhodochrosite to study its properties.

Definition: A mineral that is pink to rose-red in color, made mainly of manganese silicate, and often used for decorative purposes.

Example: The jewelry was beautifully crafted from rhodonite, showcasing its vibrant pink color.

Definition: A light-sensitive pigment found in the retina of the eyes, crucial for seeing in low light conditions.

Example: Rhodopsin plays a key role in our ability to see at night.

Definition: The part of the brain located at the back of the head, which includes structures like the cerebellum and the brainstem, responsible for functions such as balance, coordination, and vital bodily processes.

Example: The doctor explained that the rhombencephalon plays a crucial role in controlling basic life functions.

Definition: Describing a shape that has three sides of equal length and angles that are not right angles.

Example: The crystal structure of the mineral is rhombohedral, giving it a unique geometric appearance.

Definition: A three-dimensional shape that has six flat surfaces, all of which are rhombuses.

Example: The architect designed a building in the shape of a rhombohedron to create a unique look.

Definition: A muscle located in the upper back that connects the spine to the shoulder blade, helping to move and stabilize the shoulder.

Example: The rhomboideus muscle plays an important role in retracting the shoulder blades during certain movements.

Definition: A type of volcanic rock that is fine-grained and similar to granite, often formed from lava and can show flow lines.

Example: The geologist collected a sample of rhyolite to study its mineral composition.

Definition: Relating to a type of volcanic rock that is light in color and has a high silica content.

Example: The geological survey revealed that the area was rich in rhyolitic formations.

Definition: A type of enzyme that helps to break down RNA molecules in the body.

Example: Ribonuclease plays a crucial role in the digestion of RNA in cells.
