The science of describing, naming, and classifying extant and extinct organisms is:__________
Sloan [31]

The answer is Taxonomy.

The science of describing, naming, and classifying extant and extinct organisms is <u>Taxonomy</u>.

What is taxonomy?

All of the world's plants, animals, and microorganisms are included in taxonomy, which is the science of naming, describing, and classifying species. Taxonomists identify, describe, and classify species, particularly those that are novel to science, using morphological, behavioral, genetic, and biochemical observations. Taxonomy recognizes and catalogs the elements of biological diversity, offering the fundamental information necessary for the management and application of the Convention on Biological Diversity. Unfortunately, our understanding of taxonomy is far from complete. Taxonomists have identified roughly 1.78 million species of animals, plants, and microorganisms throughout the past 250 years of study, but the true number of species is unknown and likely between 5 and 30 million.

Generally speaking, superficial categorization of living things develop according to necessity. Any crawling object, such as a snake, earthworm, intestinal parasite, or dragon, has been referred to, respectively, by the Anglo-Saxon phrases worm and fish. There are more anatomical distinctions between a shellfish and a starfish than there are between a bony fish and a man, despite the fact that the terms shellfish, crayfish, and starfish all include the term "fish." There are many different types of vernacular names. The English robin (Erithacus rubecula) is not the American robin (Turdus migratorius), for instance, while the mountain ash (Sorbus) only superficially resembles a real ash.

Each kernel of corn receives one allele from

each parent for the traits of color and texture.

Option B

<h3><u>Explanation:</u></h3>

Corn kernels are actually the seeds of corn. Corn kernels are formed because of the fertilization of both the Pollen and the ovule of the corn plants. This pollens and the ovules are formed by means of meiosis which takes different alleles of the same gene from both the parents and both the chromosomes of each parents. This is why during meiosis the events of crossing over and independent assortment leads to the variation of characters into the offspring. This is why the kernel colours of the the same ear of the corn remains same. This is how the corn plant receives the the kernel colours from both the parents and their colours remain constant for one particular ear. Also the gene of texture is achieved from both the parents by means of meiosis just like the corn colour. So there also independently assorted.
