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 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: Having the shape of half a sphere.

Example: The dome of the building is hemispherical, giving it a unique appearance.

Definition: A space in the body of certain animals, like arthropods and some mollusks, where blood flows and circulates around the organs.

Example: The hemocoel allows the blood to move freely between the organs of the crab.

Definition: A bluish protein that contains copper and helps carry oxygen in the blood of some animals like mollusks and arthropods.

Example: Hemocyanin is responsible for the blue color of the blood in some species of octopus.

Definition: A type of cell found in the blood, particularly in invertebrate animals, that plays a role in various bodily functions.

Example: Hemocytes are essential for the immune response in many invertebrates.
