Definition: Relating to a structure made up of four parts or units.

Example: The tetrameric protein plays a crucial role in cellular functions.

Definition: Describing something that has four similar parts or is arranged in groups of four.

Example: The tetramerous flower has petals that are grouped in sets of four.

Definition: Referring to an organism or cell that has four sets of chromosomes instead of the usual two sets.

Example: The tetraploid plant species can produce larger fruits than its diploid relatives.

Definition: An organism or cell that has four complete sets of chromosomes, which is more than the usual two sets found in diploid organisms.

Example: The scientist studied a tetraploid plant to understand its genetic variations.

Definition: The state in which a cell has four complete sets of chromosomes instead of the usual two.

Example: Tetraploidy can occur in some plants, leading to larger cell sizes and increased vigor.

Definition: A type of chemical compound made up of four connected pyrrole rings, often found in natural pigments like chlorophyll.

Example: Chlorophyll is a tetrapyrrole that plays a crucial role in photosynthesis.

Definition: A type of chemical compound that contains a specific group of atoms known as tetrazole, often used in scientific tests to measure metabolic activity in cells.

Example: The researchers used tetrazolium to assess the viability of the cells in their experiment.

Definition: A type of vacuum tube that has four main components: an anode, a cathode, a control grid, and an extra electrode, used in electronic circuits.

Example: The radio engineer replaced the faulty tetrode to improve the signal quality.

Definition: A strong poison that affects the nervous system, commonly found in puffer fish and some newts, which prevents nerves from sending signals by blocking sodium ions.

Example: Tetrodotoxin is extremely dangerous and can cause paralysis if ingested.

Definition: A type of chemical compound that contains four oxygen atoms in its molecular structure.

Example: Ruthenium tetroxid is used in various chemical reactions due to its unique properties.

Definition: A chemical substance that has four oxygen atoms in each molecule.

Example: Dinitrogen tetroxide is a common example of a tetroxide used in rocket propellants.
