The Linnaean system added more levels onto the hierarchy of complexity that Aristotle developed.

The linnaean system of classification of taxonomy was developed by swedish naturalist named Carolus Linneaus in the mid 1700. He developed a way to organise and name species. He based his classification on physical traits of organisms and uses binomial numenclature to identify organisms. The seven major level of classification are kingdom, phylum, class, order, family,genus and species.

<h3>What is Linnaean system of classification ?</h3>

Similarities in outward physical characteristics serve as the foundation for the Linnaean system. A hierarchy of taxa, from the kingdom to the species, makes up this system. Every species has its own distinctive two-word Latin name. The most recent taxon, the domain, is more extensive and encompassing than the kingdom.

  • Because it encouraged the use of binomial nomenclature to distinguish between each species, the Linnaean system is significant. Scientists could communicate without the use of deceptive common names once the approach had been accepted.

ATP hydrolysis _______.
yaroslaw [1]

Answer:

The correct answer is to ADP and Pi is the most common mechanism for transferring free energy to drive endergonic reactions.

Explanation:

Many endergonic reactions(the free energy change of these reactions are highly positive) proceed in a thermodynamically unfavorable manner.

     To make those reactions thermodynamically favorable,these reactions are coupled with hydrolysis of high energy compound such as hydrolysis of ATP to ADP and Pi.

    As a result the free energy change of those reactions becomes negative which allow those reactions to proceed in a thermodynamically favorable manner.
