Every living organism has what classification groups as its name?

Answers

Every living organism has a scientific name that is classified into several hierarchical groups, including domain, kingdom, phylum, class, order, family, genus, and species. This classification system helps scientists organize and understand the diversity of life on Earth.

1. Domain: This group represents the highest level of classification and categorizes organisms into three domains: Archaea, Bacteria, and Eukarya. Archaea and Bacteria contain prokaryotic organisms, while Eukarya includes eukaryotic organisms.

2. Kingdom: Within each domain, organisms are further classified into different kingdoms. For example, in the domain Eukarya, there are kingdoms such as Animalia, Plantae, Fungi, Protista, and more. Each kingdom includes organisms with similar characteristics and evolutionary relationships.

3. Phylum: The phylum is the next level of classification and groups organisms based on certain shared characteristics. For example, in the animal kingdom, phyla include Chordata (which includes vertebrates) and Arthropoda (which includes insects, spiders, and crustaceans).

4. Class: Within each phylum, organisms are further divided into classes based on additional shared characteristics. For example, in the class Mammalia, animals have mammary glands and give birth to live young.

5. Order: Orders are the next level of classification and further divide organisms within a class based on shared characteristics. For example, within the order Carnivora, animals have specialized teeth for eating meat.

6. Family: Families group organisms within an order based on more specific shared characteristics. For example, within the family Felidae, animals have retractable claws and are known as cats.

7. Genus: The genus is a more specific classification group that groups closely related species together. For example, the genus Panthera includes big cats such as lions, tigers, and leopards.

8. Species: The species is the most specific level of classification and refers to a group of organisms that can interbreed and produce fertile offspring. Each species has a unique scientific name, consisting of the genus and species names. For example, the scientific name for lions is Panthera leo.

Calcite will scratch gypsum. This is an example of the physical characteristics called ____. a. hardness c. fracture b. streak d. cleavage

Answers

The right answer is A. Hardness.

The hardness of a material defines the resistance of a surface of the sample to the penetration of a punch, for example a hardened steel ball (Brinell hardness) or a diamond pyramid (Vickers hardness). If it resists well, it is said hard, otherwise it is soft. The hardness is measured on different scales depending on the type of material considered.

Unlike minerals whose hardness is characterized by scratching (Mohs scale), bounce or penetration tests are usually used to characterize the hardness of metals, plastics and elastomers. These tests have the advantage of being simpler to perform and give reproducible results. There is a wide variety of possible hardness tests, they are widely used in quality control to compare or estimate the strength or stiffness of materials.

The answer to the question stated above is letter A. hardness
