Vertical gene transfer is the passage of genes from parent to offspring, and horizontal ( also called lateral ) gene transfer occurs when genes jump between unrelated organisms, a common phenomenon especially in prokaryotes ; a good example of this is the acquired antibiotic resistance as a result of gene exchange between various bacteria leading to multi-drug-resistant bacterial species.

Red tides in the Gulf of Mexico are a result of high concentrations of Karenia brevis, a microscopic marine algae that occurs naturally but normally in lower concentrations.

In the course of economic relations, the working class and the bourgeoisie continually engage in class struggle, wherein the capitalists exploit the workers, whilst the workers resist their economic exploitation, which occurs because the worker owns no means of production, and, to earn a living, he or she seeks employment from the bourgeois capitalist ; the worker produces goods and services that are property of the employer, who sells them for a price.
