"Hemimetabolism" Natural Recordings by Native Speakers
Hemimetabolism is a type of insect development in which insects undergo a series of molts, or shedding of their exoskeleton, without a distinct pupal stage. It is a characteristic of insects in the subclass Pterygota, which includes all winged insects except for Holometabola, such as butterflies and beetles. In hemimetabolous insects, the young insects, or nymphs, resemble small adults and go through a series of molts as they grow and develop, eventually reaching adulthood.
A hemihedron is a polytope that is half the size of the complete polytope it is derived from, and it is formed by deleting one vertex from a complete polytope.
Hemihepatectomy is a surgical procedure where one half of the liver is removed, known as a hemi-liver resection. It is typically performed in cases of liver cancer, liver cirrhosis, or liver trauma to remove a damaged or diseased portion of the liver and improve liver function.
Hemihypertrophy is a rare medical condition characterized by an unusual and unexplained difference in the size of bodily organs or limbs on one side of the body, compared to the other side.
Hemimandibulectomy is a surgical procedure in which half of the lower jawbone (mandible) is removed. It is typically performed to treat benign or malignant tumors, infections, or injuries that affect the mandible.
Hemimellitic refers to a type of organic compound that contains four methyl groups and has the general formula C6H6O6. This term is used in chemistry to describe the structure and properties of these compounds, which are often found in natural products and have important biological functions.
Hemimetabolic refers to a type of insect development that involves a gradual process of metamorphosis, characterized by a series of distinct larval stages, each with a different physical characteristic. In hemimetabolism, the young insect, called a nymph, resembles a small adult and goes through several molts as it grows and develops. Examples of insects that undergo hemimetabolic development include cockroaches, grasshoppers, and crickets.
Hemimetabolous refers to a type of insect developmental pattern in which the young, or nymphs, look like small versions of the adults and go through a series of molts (shedding of skin) to reach adulthood. This is in contrast to endopterygotes, which undergo a dramatic transformation, or metamorphosis, from larva to pupa to adult. Hemimetabolous insects include true flies, dragonflies, grasshoppers, and crickets. Examples of hemimetabolous insects include the common housefly, the cricket, and the dragonfly.
Hemimethylated refers to the state of a DNA molecule where only one of its two nucleotide bases has been methylated, which means a methyl group has been added to one of its nitrogen atoms. This is in contrast to fully methylated DNA where both nucleotide bases have been methylated, or demethylated DNA where neither nucleotide base has been methylated.
Hemimorphic refers to a type of crystal or mineral that has grown to form two separate parts, each with a different growth pattern, and which are connected at a midline. This term is often used to describe certain types of quartz crystals, such as smoky quartz or rose quartz, that have developed different colors or inclusions on either side of the midline.
Hemimorphism is a term used in geology and crystallography to describe a crystal structure that has a partially symmetrical lattice and partially non-symmetrical lattice. In other words, the crystal structure has a mix of symmetrical and asymmetrical features. This is in contrast to a monopoly crystal, which has a completely symmetrical lattice, or an anhedral crystal, which has no clear symmetry. Hemimorphism is often observed in minerals that have a layered or planar structure, such as mica or phyllosilicate minerals.
Hemimorphite is a species of mineral, a zinc oxide hydroxide. It is a rare earthy mineral with a usually limestone-yellow to yellow-brown color. It is a twins crystal, meaning that it forms in a specific way where two individual crystals grow together, often with their faces parallel to each other.
Hemin is a type of porphyrin, a class of organic compounds. It is also known as proto IX or hematin.
Ernest Hemingway was an American novelist, short-story writer, and journalist who is known for his distinctive writing style, which is characterized by simplicity, clarity, and a focus on concrete, descriptive details. He is often credited with developing the "iceberg principle" of writing, where much of the meaning is left unsaid and the reader is expected to infer the underlying emotions and themes.
