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: Having beliefs or opinions that are different from what is generally accepted or traditional.

Example: His heterodox views on education sparked a lot of debate among the teachers.

Definition: A belief or opinion that differs from the accepted or traditional views, especially in religion or philosophy.

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: In many species, males are heterogametic, producing two types of sperm cells.

Definition: The process in which an individual produces gametes that have different numbers of chromosomes, typically seen in one sex of a species.

Example: In some species, heterogamety leads to the production of male and female gametes with different genetic compositions.

Definition: Describing a type of reproduction that involves different types of gametes or the presence of both male and female reproductive structures.

Example: Many plants are heterogamous, having both male and female flowers on separate parts of the same plant.
