an element which has valency 2
bivalent
A bivalent chemical element has the valence 2 as calcium for ex.
Because of a preliminary FMD diagnosis of both 0 and Asia, an order for a bivalent vaccine was placed.
A bivalent contains two duplicated homologous chromosomes.
A benzylidene is the bivalent radical C6H5-CH=.
The equation that represents the dissociation in solution of a salt formed at a trivalent cation and a bivalent anion is typically written as: M3X2(s) → 3M3+(aq) + 2X2-(aq) In this equation, M represents the trivalent cation and X represents the bivalent anion. The salt dissociates into three trivalent cations and two bivalent anions in the aqueous solution.
It is not ionic. It is a covalent compound.
A bivalent at the beginning of prophase I is composed of two homologous chromosomes that have already replicated into sister chromatids. Each homologous chromosome consists of two sister chromatids joined by a centromere. The bivalent forms as the homologous chromosomes pair up and undergo synapsis.
bivalent is another name for tetrad
Bivalent formation occurs during meiosis, specifically during prophase I. This is when homologous chromosomes pair up and exchange genetic material through a process called crossing over. Bivalents are formed as a result of this pairing and crossing over.
Bivalency is the quality of being bivalent - relating to a pair of homologous synapsed chromosomes which occur during meiosis.
A bivalent refers to an antibody that can bind to two identical epitopes on an antigen. This dual binding enhances the antibody's ability to neutralize antigens and promote immune responses. Bivalency is a key feature of antibodies that contribute to their effectiveness in combating infections and diseases.
