Most obviously, they differ in the fact that even unicellular protistans are more complex â not to mention eukaryotic. Protistans have membrane-bound nuclei, organelles (including chloroplasts), and endomembrane systems, as well as multiple strands of DNA with histones and other proteins attached.
Breach of contract is a legal cause of action in which a binding agreement or bargained-for exchange is not honored by one or more of the parties to the contract by non-performance or interference with the other party's performance.or example, when a contract specifies time is of the essence and one party to the contract fails to meet a contractual obligation in a timely fashion, the other party could sue for damages for a major breach.
For example, if the contract specifies the sale of a box of tennis balls and the buyer receives a box of footballs, the breach is material. When a breach is material, the nonbreaching party is no longer required to perform under the contract and has the immediate right to all remedies for breach of the entire contract.
