Answer:
c. Each key is organized as a flowchart.
Explanation:
A dichotomous key is a device that enables users to recognise natural world objects, such as wildflowers, trees, reptiles, mammals, fish and rocks. it used for the Identification whereby groups of species are frequently divided into two categories with increasing sequential division, more information on the basic characteristics of a particular organism is released.
Dichotomous keys are represented in two ways including either as descriptive representation in which a series of paired statements arraged in a numbered sequence or as a branching flowchart (diagrammatic representation)

According to Gloger's rule, endothermic creatures should have darker hues in hot, rainy areas. The so-called complex Gloger's rule also states that animals should be more rufous in warm, dry regions.
Explains the connection between animal color variation and large-scale climate gradients. Bernhard Rensch gave it that name in 1929 to honor Constantin W.L. Gloger, who was one of the first to write about relationships between animal pigmentation and temperature in 1833.
Gloger's rule, as it is known now, states that mammals and birds should be darker in warm, humid settings than in colder, dry ones.
Gloger's rule-related color variation is mostly caused by variations in melanin pigmentation, according to this quick reference.
The most prevalent pigment in birds and mammals, melanin's are of two primary types: pheomelanin's, which produce brown, buff, and rufous colors, and eumelanin's, which produce black and different shades of grey. Both generate intermediate hues when combined.

Oxygen locks onto a molecule called hemoglobin in the red blood cells. The newly oxygenated blood leaves the lungs through the pulmonary veins and heads back to the heart. It enters the heart in the left atrium, then fills the left ventricle so it can be pumped into the systemic circulation.
