Aquatic mollusk ,like a scallop or a mussel are bivale which mean animals that consist in two hinged shells .
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.
an element which has valency 2
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
Bivalency is the quality of being bivalent - relating to a pair of homologous synapsed chromosomes which occur during meiosis.
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.
