Which of the following lists represents a five-kingdom system for classifying organisms? a. plants, animals, bacteria, yeast, mammals b. amphibians, protists, monerans, reptiles, birds c. mammals, reptiles, amphibians, birds, fungi d. plants, animals, fungi, protists, monerans

D. Plants, Animals, Fungi, Protists, Monerans

Explanation:

Classifying living beings is not an easy task, and to date this challenge has not been completely solved. Although several researchers have been working since antiquity to achieve the lowest possible classification of organisms, no proposed classification is without problems.

Initially, the classification systems were simple, not least because genetic and evolutionary mechanisms were not known as they are today. Linnaeus, for example, classified living beings into only two groups: Animal Kingdom and Vegetal Kingdom. With the knowledge of microscopic organisms, it was realized that it was not possible to classify living beings only in animals and plants, so the concept of kingdoms has evolved and today we consider that the five kingdoms of living beings are: Monera Kingdom, Protista Kingdom, Kingdom Fungi, Kingdom Animalia and Kingdom Plantae.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
