Often asked: Which Is Not A Commonly Used Concept Of Biological Rarity?

Which is NOT a commonly used concept of biological rarity? Rare species face many adverse possibilities. Which form of rarity is potentially the most catastrophic in the face of a disease outbreak? Which group of species is most likely to exhibit low population density?

Which kind of species do we expect to successfully colonize a new ecosystem first?

The first species to colonize an area after a major disturbance are called pioneer species; they help to form the new environment. Secondary succession occurs after a disturbance such as a forest fire, where there is still some organic matter to allow new plants to grow.

Which family of genes was responsible for the development of the multicellular body plan in all animals except sponges?

Zic family genes encode five C2H2-type zinc finger domain-containing proteins that have many roles in animal development and maintenance. Recent phylogenetic analyses showed that Zic family genes are distributed in metazoans (multicellular animals), except Porifera (sponges) and Ctenophora (comb jellies).

What biological characteristics allowed the species to colonize most parts of the world?

Organisms are able to colonize all environments that fall within the limits of habitability, i.e., conditions of low (Kappen et al. 1996) to high temperatures (up to 121°C, Kashefi and Lovley 2003), low water availability (Billi and Potts 2002), extreme acidity (Amaral Zettler et al.

What are the 4 types of animals?

Basic Types of Animals and Their Characteristics

  • Animals with a backbone are vertebrates.
  • Vertebrates belong to the phylum called Phylum Chordata.
  • Vertebrates are further broken down into five classes: amphibians, birds, fish, mammals, and reptiles.
  • Animals without a backbone are invertebrates.

What are the common characteristics among the three groups of animals?

Answer

  • All animals are multicellular organisms. Their body is made up of more than one cell.
  • Animals are eukaryotic organisms.
  • All animals are heterotrophic in nature.
  • Animals produce more number through the sexual mode of reproduction.

What are some problems with the biological species concept?

In summary, the major limitations of the biological species concept are that it is inapplicable to: (1) fossil species; (2) organisms reproducing asexually or with extensive self-fertilization; and (3) sexual organisms with open mating systems (species that freely hybridize).

Which of the following is a good example of a metapopulation?

Which of the following is a good example of a metapopulation? those in which a species goes extinction from a given area. Biodiversity hot spots often contain significant numbers of species in impending risk of extinction.

What inhibits fossilization of a dead organism? lack a backbone.
