Which taxonomic group is the smallest?
Species is the smallest and least inclusive of the taxonomic categories.
Which is the smallest taxonomic group having cranium?
Superclass Tetrapoda comprises the first four-limbed vertebrates which include amphibians, reptiles, mammals, birds and some extinct fishes. It is characterized by the cranium, vertebral column, ventral heart and pulmonary respiration. Hence, option D is correct.
Which level of classification contains all the others Kingdomdomaingenusclass?
The correct answer is option (B) domain. Life⇒Domain⇒Kingdom⇒Phylum⇒Class⇒Order ⇒Family⇒Genus⇒Species. Thus, domain is the level of classfication that includes the kigdom, class and genus.
Which characteristics are used to differentiate between the six kingdoms?
The characteristics of body type, cell type, cell structure, and nutrition are used in order to differentiate (or put in categories) between the six kingdoms.
What are the 8 Kingdoms?
Eight kingdoms model
- The first two kingdoms of life: Plantae and Animalia.
- The third kingdom: Protista.
- The fourth kingdom: Fungi.
- The fifth kingdom: Bacteria (Monera)
- The sixth kingdom: Archaebacteria.
- The seventh kingdom: Chromista.
- The eighth kingdom: Archezoa.
- Kingdom Protozoa sensu Cavalier-Smith.
What is the 3 domains of life?
According to this system, the tree of life consists of three domains: Archaea, Bacteria, and Eukarya. The first two are all prokaryotic microorganisms, or mostly single-celled organisms whose cells have no nucleus.
What is the oldest domain of life?
Archaeabacteria
What are the 7 characteristic of life?
Properties of Life. All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.

Which characteristic of life is the most important?
Sexual or Asexual Reproduction One of the most important characteristics of life is an organism’s ability to reproduce.
What are the 8 characteristics of life?
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these eight characteristics serve to define life.
What are six characteristics?
To be classified as a living thing, an object must have all six of the following characteristics:
- It responds to the environment.
- It grows and develops.
- It produces offspring.
- It maintains homeostasis.
- It has complex chemistry.
- It consists of cells.
How do you remember the 7 characteristics of life?
For example, a really common mnemonic device used in biology is “MRS GREN”. This acronym is used to help us remember the 7 characteristics of life (Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition).
What are the 5 requirements of life?
So, as far as we know, the 5 requirements for life beyond Earth include: Carbon, water, energy, time, and luck.
What are the 4 requirements of life?
It is useful to categorize the requirements for life on Earth as four items: energy, carbon, liquid water, and various other elements. These are listed in Table 1 along with the occurrence of these factors in the Solar System (2).
What are the 3 requirements for life?
Life as we know it requires biogenic elements, a source of energy, liquid water, and a suitable, reasonably stable environment for evolution to take place.
What are the essential requirements for life?
While the development of tools, plumbing systems and food preservation have enabled modern man to live life with many creature comforts, the truth remains that the requirements for human survival are quite basic. Physiological needs include air, water, food, shelter, sanitation, touch, sleep, and personal space.
What characteristics of Earth allow liquid water to exist?
The Earth’s atmospheric pressure and relatively stable temperatures make liquid water possible. Our orbit within the sun’s habitable zone prevents…
What is needed for life on another planet?
The standard definition for a habitable planet is one that can sustain life for a significant period of time. As far as researchers know, this requires a planet to have liquid water. To detect this water from space, it must be on the planet’s surface.
What is the basis of all life?
All living organisms are made up of one or more cells, which are considered the fundamental units of life. Even unicellular organisms are complex! Inside each cell, atoms make up molecules, which make up cell organelles and structures. In multicellular organisms, similar cells form tissues.
Why is a fire not alive?
The reason fire is non-living is because it does not have the eight characteristics of life. Fire does the same thing, but it has no body or has no structured cell system. People think fire is living because it moves and needs oxygen. Also, it is able to spread across the ground.
Is a rock alive?
Rocks themselves are not alive. But in a coral reef rock-like lime substance is continually produced from the skeletons of dead rock corals and the shells of mussels and other creatures which are bound together by sponges and calcareous algae.
Is water alive Yes or no?
Some examples of non-living things include rocks, water, weather, climate, and natural events such as rockfalls or earthquakes. Living things are defined by a set of characteristics including the ability to reproduce, grow, move, breathe, adapt or respond to their environment.
