Definition: Relating to a group of marine animals that are part of the phylum Hemichordata, which includes acorn worms and pterobranchs.

Example: The hemichordate species found in the ocean exhibit unique characteristics that distinguish them from other marine life.

Definition: A type of marine animal that is similar to a worm and belongs to the phylum Hemichordata, characterized by having a simple backbone structure and gill slits.

Example: The hemichordate is an interesting creature that helps scientists understand the evolution of chordates.

Definition: A shape or structure that is half of a circle, often used in architecture or design.

Example: The amphitheater was built in a hemicycle shape to enhance the acoustics.

Definition: Describing a crystal that has only half of the faces needed for full symmetry.

Example: The hemihedral crystal structure gives the mineral a unique appearance.

Definition: A type of compound that contains water molecules in a specific ratio, where there is one water molecule for every two molecules of the main substance.

Example: Plaster of Paris is a common example of a hemihydrate used in construction and art.

Definition: Describing a type of insect development that does not include a pupal stage, where the young resemble smaller versions of the adults and grow through a series of molts.

Example: Grasshoppers are hemimetabolous insects, as they develop through several nymph stages before becoming adults.

Definition: Describing a crystal that has different shapes or structures at each end along its axis, making it asymmetrical.

Example: The mineral exhibited hemimorphic properties, with distinct forms at both ends of the crystal.

Definition: A property in crystallography where the two ends of a crystal are different from each other in their shapes or surfaces.

Example: The mineral exhibits hemimorphism, showing distinct features at both ends of the crystal.

Definition: A reddish-brown crystalline compound derived from hemoglobin, used in laboratory tests to detect blood.

Example: The scientist used hemin to test the blood sample for hemoglobin presence.

Definition: A condition where one side of the body is paralyzed, often due to brain injury or disease.

Example: After the stroke, he was diagnosed with hemiplegia, which affected his left side.

Definition: Relating to or affected by a condition that causes paralysis on one side of the body.

Example: The hemiplegic patient requires special care and rehabilitation to regain mobility.
