Definition: An atom that is not carbon, found in the structure of certain chemical compounds, especially in rings.

Example: In the compound, the nitrogen acts as a heteroatom, providing different chemical properties.

Definition: Describing a type of tail fin where the upper part is bigger than the lower part, and the backbone extends into the upper part, commonly seen in sharks.

Example: Sharks have a heterocercal tail that helps them swim efficiently.

Definition: Describing something that has different colors or consists of different wavelengths.

Example: The artist used heterochromatic paints to create a vibrant and colorful mural.

Definition: A type of chromosomal material that is tightly packed and does not actively participate in gene expression, often appearing as dense areas in chromosomes.

Example: Heterochromatin plays a crucial role in maintaining the structure of chromosomes during cell division.

Definition: A type of chemical compound that contains a ring structure made up of at least one atom that is not carbon, such as nitrogen, oxygen, or sulfur.

Example: Many pharmaceuticals are based on heterocycles due to their unique properties.

Definition: Describing a type of chemical compound that has a ring structure made up of different types of atoms, not just carbon.

Example: Heterocyclic compounds are important in many pharmaceuticals and agricultural chemicals.

Definition: A large, thick-walled cell found in some cyanobacteria that helps in the process of nitrogen fixation.

Example: The heterocyst plays a crucial role in the nitrogen cycle by converting atmospheric nitrogen into a usable form for plants.

Definition: A type of nucleic acid made up of two strands that come from different parent molecules.

Example: The researchers studied the heteroduplex formed during the DNA recombination process.

Definition: Relating to a method in electronics where two different frequencies are combined to create new frequencies, often used in radio and television technology.

Example: The heterodyne receiver improved the clarity of the radio signal.

Definition: To mix a radio wave with another wave of a different frequency to create a new frequency that is the sum or difference of the two original frequencies.

Example: The engineer decided to heterodyne the signals to improve the clarity of the transmission.

Definition: Referring to organisms that complete different stages of their life cycle on different hosts, which are often not related to each other.

Example: Some species of fungi are heteroecious, requiring multiple host plants to complete their life cycle.
