Answer:
1. The correct answer would be all living and extinct species.
Scientific name refers to the formal name universally used to denote a particular organism. For example, Homo sapiens is the scientific name of human species.
2. The correct answer would be phylum.
Classification hierarchy can be written as species → genus → family → order → class → phylum → kingdom → Domain.
Thus, the classes make up a phylum.
3. The most appropriate answer would be phylum and kingdom.
Carolus Linnaeus is also known as the father of taxonomy as he provided the system for classification and naming of the organisms.
He gave 7 levels classification which consisted of species → genus → family → order → class → phylum → kingdom.
4. The correct answer would be mammals.
Mammals are vertebrates which has a unique feature of presence of mammary glands. In females, mammary glands help in milk production which helps in the nourishment of young ones. Other characteristics may include war-blood, the presence of body hairs or furs, et cetera.
1. All living as well as extinct species must be provided with a scientific name.
Further Explanation:
Every individual on earth is given a scientific name through a system called binomial nomenclature. These scientific names are important as they provide information about the organism, which can be used ambiguously all across the world. This is done through a set of rules which determine that no animal is named twice and is given a unique name for its identification. For example, the name Lepomis macrochirus has been given to bluegill sunfish and cannot be provided to any other species of animals. The scientific names also determine the relationship between different animals. These names contain two parts, one is a generic name and the other is a specific name. Lepomis is the generic name, while macrochirus is the specific name of the bluegill sunfish. The scientific names must be given to all the species whether alive or extinct to keep track of a number of species already named and also to avoid confusion of naming the same species more than once.
2. The phylum ranks third in the classification system. It involves different classes that together make up a phylum.
Further Explanation:
In the taxonomic ranking, domain and kingdom are followed by phylum. The organisms in a particular phylum share specific characteristics that differentiate them from the organisms of other phyla. The number of phyla under animal, plants, and fungi are approximately 35, 12, and 7, respectively.
3. According to the classification of Linnaeus, the organisms were divided into three groups, such as plants, animals, and minerals. These groups were termed as a kingdom. These kingdoms were separated into classes that were further partitioned into orders. Therefore, the kingdom and orders are the highest taxonomical levels in Linnaeus’s classification system.
Further Explanation:
Taxonomy involves classifying and naming organisms according to their characteristics. Carolus Linnaeus, a naturalist, developed a classification system using binomial nomenclature. He classified the species in a hierarchical manner in which the organisms follow the hierarchy, such as kingdom, class, order, genus, and species. Later certain changes were made in the hierarchy and some levels were added. For example, the highest and broadest level was named domain. The phyla were included under the kingdom, which was followed by the class. The class was further divided into order, followed by family, genus, and lastly, species.
4. The characteristics of the class Mammalia includes the presence of mammary gland for the production of milk, presence of hair in the body, middle ear bones which are three in numbers, and warm-bloodedness.
Further Explanation:
The animals in the class Mammalia are referred to as mammals. Mammals can be egg-laying called monotremes or can be placental and marsupials. It is estimated that there are approximately 5000 mammal species that are differentiated into 1200 genera and 153 families. The mammals can adapt to different environmental conditions, which are the main reason for their successful establishment so far. The evolution of mammals occurred from reptilian-like ancestors. Modern mammals evolved to produce mammary glands for milk secretion, which is absent in monotremes, who release milk from the stomach and not from the nipples. The hair in the body was also produced in the course of development. The hair provides insulation, helps in touch sensation, and provides color patterning.
